NAME
"pfm" - Personal File Manager for Linux/Unix

SYNOPSIS
"pfm [" directory "] [" "-s, --swap "directory "]" " [" "-c, --colorset
"string "]" " [" "-l, --layout "number "] [" "--login" "]" " [" "-o,
--sort "mode "]"

"pfm { --help | --usage | --version }"

DESCRIPTION
"pfm" is a terminal-based file manager, based on PFM.COM for MS-DOS.

All "pfm" commands are accessible through one or two keystrokes, and a
few are accessible with the mouse. Most command keys are case-
insensitive. "pfm" can operate in single-file mode or multiple-file
mode. In single-file mode, the command corresponding to the keystroke
will be performed on the current (highlighted) file only. In multiple-
file mode, the command will apply to a selection of files.

Note that throughout this manual page, file can mean any type of file,
not just plain regular files. These will be referred to as regular
files.

This manual pertains to pfm version 2.12.3.

OPTIONS
Most of "pfm"'s configuration is read from a config file. The default
location for this file is $HOME/.pfm/.pfmrc, but an alternative
location may be specified using the environment variable PFMRC. If
there is no config file present at startup, one will be created. The
file contains many comments on the available options, and is therefore
supposed to be self-explanatory. "pfm" will issue a warning if the
version number of an existing config file is less than the version of
"pfm" you are running, and will offer to update it to its own version.
Alternatively, you could let "pfm" create a new default config file and
compare the changes with your own settings, so that you can configure
the new options right away. See also the Config command under "MORE
COMMANDS" below, and "DIAGNOSIS".

There are two commandline options that specify starting directories.
The CDPATH environment variable is taken into account when "pfm" tries
to find these directories.

directory
The directory that "pfm" should initially use as its main
directory. If unspecified, the current directory is used.

--help
Print extended usage information, then exit.

-c, --colorset string
Start "pfm" using the specified colorset (as defined in the
.pfmrc).

-l, --layout number
Start "pfm" using the specified column layout (as defined in the
.pfmrc).

--login
Start "pfm" as a login shell. "pfm" will change its name to "-pfm"
and start a new session using setsid().

-o, --sort mode
Start "pfm" using the specified sort mode (as shown by the F6
command).

-s, --swap directory
The directory that "pfm" should initially use as swap directory.
(See also below, under the F7 command).

There would be no point in setting the swap directory and
subsequently returning to the main directory if 'persistentswap' is
turned off in your config file. Therefore, "pfm" will swap back to
the main directory only if 'persistentswap' is turned on.

--usage
Print concise usage information, then exit.

--version
Print current version, then exit.

NAVIGATION
Navigation through directories is essentially done using the arrow keys
and the vi(1) cursor keys (hjkl). The following additional navigation
keys are available:

Movement inside a directory:

─────────────────────┬───────────────────────────────────────────
up arrow, down arrow │ move the cursor by one line
k, j │ move the cursor by one line
-, + │ move the cursor by ten lines
CTRL-E, CTRL-Y │ scroll the screen by one line
CTRL-U, CTRL-D │ move the cursor by half a page
CTRL-B, CTRL-F │ move the cursor by a full page
PgUp, PgDn │ move the cursor by a full page
HOME, END │ move the cursor to the top or bottom line
SPACE │ mark the current file, then move the
│ cursor one line down
─────────────────────┴───────────────────────────────────────────

Movement between directories:

─────────────────────┬───────────────────────────────────────────
l, right arrow │ chdir() to a subdirectory
h, left arrow │ chdir() to the parent directory
ENTER │ chdir() to a subdirectory
ESC, BS │ chdir() to the parent directory
─────────────────────┴───────────────────────────────────────────

If the option 'chdirautocmd' has been specified in the .pfmrc file, pfm
will execute that command after every chdir(). This can be used e.g. to
set the title of an xterm window.

Note: the l and ENTER keys function differently when the cursor is on a
non-directory file (see below under Link and "LAUNCHING FILES"
respectively).

COMMANDS
Attribute
Changes the mode of the file if you are the owner. The mode may be
specified either symbolically or numerically, see chmod(1) for more
details.

Note 1: the mode on a symbolic link cannot be set. See chmod(1) for
more details.

Note 2: the name Attribute for this command is a reminiscence of
the DOS version.

Copy
Copy current file. You will be prompted for the destination
filename. Directories will be copied recursively with all
underlying files.

In multiple-file mode, it is not allowed to specify a single non-
directory filename as a destination. Instead, the destination name
must be a directory or a name containing a =1 or =2 escape (see
below under cOmmand).

If clobber mode is off (see below under the ! command), existing
files will not be overwritten unless the action is confirmed by the
user.

Whether Copy follows symlinks or copies them is OS-specific; you
can change the default behavior by setting the 'copyoptions' option
in your .pfmrc. See cp(1).

Delete
Delete a file or directory. You must confirm this command with Y to
actually delete the file. If the current file is a directory which
contains files, and you want to delete it recursively, you must
respond with Affirmative to the additional prompt. Lost files
(files on the screen but not actually present on disk) can be
deleted from the screen listing without confirmation. Whiteouts
cannot be deleted; use unWhiteout for this purpose.

Edit
Edit a file with your external editor. You can specify an editor
with the environment variable VISUAL or EDITOR or with the 'editor'
option in the .pfmrc file. Otherwise vi(1) is used.

If a capital E is pressed, the foreground editor is used
('fg_editor').

Find
If the current sort mode is by filename, you are prompted for a
(partial) filename. While you type, the cursor is positioned on the
best match. Type ENTER to end typing.

If the current sort mode is not by filename, then you are prompted
for a filename. The cursor is then positioned on that file.

tarGet
Allows you to change the target that a symbolic link points to. You
must have permission to remove the current symbolic link.

The new name may use the =0 escape to modify the existing target
(see below under cOmmand).

Include
Allows you to mark a group of files which meet a certain criterion:

After / Before
files newer/older than a specified date and time

Every file
all files, including dotfiles (but not the . and .. entries)

Files only
regular files of which the filenames match a specified regular
expression (not a glob pattern!)

Directories only
all directories (but not the . and .. entries)

Greater / Smaller
files that are bigger or smaller than the provided size in
bytes.

Newmarks
files which were created during a previous multiple command and
are now denoted with a newmark (~)

Oldmarks
files which were marked (*) before a previous multiple command
and are now denoted with an oldmark (.)

User
files owned by the current user

. all dotfiles (but not the . and .. entries).

Oldmarks and newmarks may be used to perform more than one command
on the same group of files.

Note that the . and .. entries will never automatically become
marked.

There is also the option:

Invert
Inverts the selection, except for the . and .. entries, which
become unmarked.

Link
Prompts to create either:

an Absolute symlink
This will create a symlink containing an absolute path to the
target, irrespective of whether you enter a relative or an
absolute symlink name.

Example: when the cursor is on the file
/home/rene/incoming/.plan, and you request an absolute symlink
to be made with either the name ../.plan or /home/rene/.plan,
the actual symlink will become:

/home/rene/.plan -> /home/rene/incoming/.plan

a Hard link
This will create an additional hard link to the current file
with the specified name, which must be on the same filesystem
(see ln(1)).

a Relative symlink
This will create a symlink containing a relative path to the
target, irrespective of whether you enter a relative or an
absolute symlink name.

Example: when the cursor is on the file
/home/rene/incoming/.plan, and you request a relative symlink
to be made with either the name ../.plan or /home/rene/.plan,
the actual symlink will become:

/home/rene/.plan -> incoming/.plan

If a directory is specified, "pfm" will follow the behavior of
ln(1), which is to create the new link inside that directory.

In multiple-file mode, it is not allowed to specify a single non-
directory filename as a new name. Instead, the new name must be a
directory or a name containing a =1 or =2 escape (see below under
cOmmand).

If clobber mode is off (see below under the ! command), existing
files will not be overwritten.

Note that if the current file is a directory, the l key, being one
of the vi(1) cursor keys, will chdir() you into the directory. The
capital L command will always try to make a link.

More
Presents you with a choice of operations not related to the current
file. Use this e.g. to configure "pfm", edit a new file, make a new
directory, show a different directory, or write the history files
to disk. See below under "MORE COMMANDS". Pressing ESC or ENTER
will take you back to the main menu.

Name
Shows the complete long filename. For a symbolic link, this command
will also show the complete target of the symbolic link. This is
useful in case the terminal is not wide enough to display the
entire name, or if the name contains non-printable characters. Non-
ASCII characters and control characters will be displayed as their
octal, decimal (html entity-like) or hexadecimal equivalents like
the examples in the following table.

The 'defaultradix' config file option specifies the radix that will
initially be used. The 'defaulttranslatespace' config file option
controls whether spaces will initially be converted as well.

When the name is shown in its converted form, pressing N will
change the radix, and pressing SPACE will toggle the translation of
spaces. Any other key will exit the N command.

Examples:

────────────────┬──────────────────────────────────────
│ representation in radix
character ├──────────────────────────────────────
│ octal hexadecimal decimal
────────────────┼──────────────────────────────────────
CTRL-A │ \001 \0x01
space │ \040 \0x20
c cedilla (ç) │ \347 \0xe7 ç
backslash (\) │ \\ \\ \\
────────────────┴──────────────────────────────────────

cOmmand
Allows execution of a shell command. After the command completes,
"pfm" will resume. If the command is "cd", "pfm" itself will change
to that directory.

On the commandline, you may use several special abbreviations,
which "pfm" will replace with the current filename, directoryname
etc. (see below). These abbreviations start with an escape
character. This escape character is defined with the option
'escapechar' in your .pfmrc file. By default it is =. (Previous
versions of "pfm" used \, but this was deemed too confusing because
backslashes are parsed by the shell as well. This manual page (and
the default config file) will assume you are using = as
'escapechar').

The following abbreviations are available:

=1 the current filename without extension (see below)

=2 the current filename, complete

=3 the full current directory path

=4 the mountpoint of the current filesystem

=5 the full swap directory path (see F7 command)

=6 the basename of the current directory

=7 the extension of the current filename (see below)

=8 a space-separated list of all marked filenames. If the =8
escape takes the form prefix=8suffix, then the prefix and
suffix strings are applied to each of the names.

=9 the full previous directory path (see F2 command)

=0 the symlink target if the current file is a symlink; otherwise
an empty string

== a single literal =

=e the editor specified with the 'editor' option in the config
file

=E the 'foreground' editor, specified with the 'fg_editor' option
in the config file. This is expected to be defined as an editor
that does not fork into the background. "pfm" uses this editor
in a few cases so that it can wait for its results.

=p the pager specified with the 'pager' option in the config file

=v the image viewer specified with the 'viewer' option in the
config file

The extension of the filename is defined as follows:

If the filename does not contain a period at all (e.g. hosts) or
only has an initial period (e.g. .profile), then the file has no
extension (=7 is empty) and its whole name is regarded as =1.

If the filename does contain a non-initial period (e.g. mail.log or
.profile.old), the extension =7 is defined as the final part of the
filename, starting at the last period in the name. The filename =1
is the part before the last period.

In all cases, the concatenation of =1 and =7 is equal to =2.

Examples:

─────────────┬──────────────────
=2 │ =1 =7
─────────────┼──────────────────
track01.wav │ track01 .wav
garden.jpg │ garden .jpg
end. │ end .
hosts │ hosts empty
.profile │ .profile empty
.profile.old │ .profile .old
─────────────┴──────────────────

See also below under "ESCAPE MODIFIERS" and "QUOTING RULES".

Print
Will prompt for a print command (default "lpr -P$PRINTER =2", or
"lpr =2" if PRINTER is unset) and will run it. No formatting is
done. You may specify a print command with the 'printcmd' option in
the .pfmrc file.

Quit
Exit "pfm". The option 'confirmquit' in the .pfmrc file specifies
whether "pfm" should ask for confirmation. Note that by pressing a
capital Q (quick quit), you will never be asked for confirmation.

Rename
Change the name of the file and/or move it into another directory.
You will be prompted for the new filename. Depending on your Unix
implementation, a pathname on another filesystem may or may not be
allowed.

If clobber mode is off (see below under the ! command), existing
files will not be overwritten unless the action is confirmed by the
user.

Show
Displays the contents of the current file or directory on screen.
You can choose which pager to use for file viewing with the
environment variable PAGER, or with the 'pager' option in the
.pfmrc file.

Time
Changes mtime (modification date/time) of the file. The time may be
entered either with or without clarifying interpunction (e.g.
2008-12-04 08:42.12). Enter . to set the mtime to the current date
and time. If the current file does not exist in the directory
(lost file or whiteout), it is touch(1)ed first.

User
Changes ownership of a file. Note that many Unix variants do not
allow normal (non-"root") users to change ownership. Symbolic links
will be followed.

Version
Updates the current file with status information of the applicable
versioning system. "pfm" will examine the current directory to
figure out which versioning system is used. Supported versioning
systems are: Subversion, CVS, Bazaar and Git. See also More -
reVision.

unWhiteout
(Only on platforms that support whiteout files). Provides the
option to remove the whiteout entry in the top layer of a
stacked/overlay filesystem, thereby restoring access to the
corresponding file in the lower layer.

eXclude
Allows you to erase marks on a group of files which meet a certain
criterion. See Include for details.

Your command
Like cOmmand (see above), except that it uses preconfigured
commands from the .pfmrc file. These commands are identified by a
single letter (case-sensitive) or digit.

Your command definitions may use =0 up to =9 and =e, =E, =p and =v
escapes just as in cOmmand, e.g.:

your[A]:svn add =8
your[c]:tar cvf - =2 | gzip > =2.tar.gz
your[t]:tar tvf =2 | =p
your[1]:vimdiff =2*

Navigation through the available commands works in the same way as
for directories (see above under "NAVIGATION"), except that ENTER
selects the highlighted command, and j and k select their own
command (as do the other letters and digits).

siZe
For directories, reports the grand total (in bytes) of the
directory and its contents.

For other file types, reports the total number of bytes in
allocated data blocks. For regular files, this is often more than
the reported file size. For special files and fast symbolic links,
the number is zero, as no data blocks are allocated for these file
types.

If the screen layout (selected with F9) does not contain the 'grand
total' column, then the 'filesize' column will temporarily be used
instead. A 'grand total' column in the layout will never be filled
in when entering the directory.

Note: since du(1) commands are not portable, "pfm" guesses how it
can calculate the size according to the Unix variant that it runs
on. If "pfm" makes an incorrect guess, please notify the author of
any corrections that should be made.

MORE COMMANDS
These commands are accessible through the main screen More command.

Acl Edit the Access Control List for this file. Note: This feature has
not yet been implemented for all Un*x variants.

WARNING: This feature has not been well tested on all Unices. Use
it at your own risk.

Any help getting the commands right would be appreciated by the
author.

Bookmark
Lists all the available bookmarks and asks the user in which slot
the current directory should be bookmarked. If the input is valid,
a new bookmark is created in the bookmark list.

Navigation through the bookmark list works in the same way as for
directories (see above under "NAVIGATION"), except that ENTER
selects the highlighted slot, and j and k select their own slot (as
do the other letters and digits).

Config pfm
This command will open the .pfmrc config file with the configured
editor. The file will be re-read by "pfm" after you exit your
editor. Options that are only modifiable through the config file
(like 'columnlayouts') will be reinitialized immediately, options
that affect settings modifiable by key commands (like
'defaultsortmode') will not.

Edit any file
You will be prompted for a filename, then your editor will be
spawned.

If a capital E is pressed, the foreground editor is used
('fg_editor').

make Fifo
Prompts for a name, then creates a FIFO file (named pipe) with that
name. See also fifo(4) and mkfifo(1).

Go to bookmark
Lists all the available bookmarks and asks the user which bookmark
should be loaded to the current directory (and file). If the input
is valid, the bookmark is loaded and a chdir() is done to the
directory.

Navigation through the bookmark list works as noted above, under
Bookmark.

sHell
Spawns your default login shell. When you exit from it, "pfm" will
resume.

foLlow
If the current file is a symlink, it is followed and the cursor
positioned at the target file.

Make new directory
Specify a new directory name and "pfm" will create it for you.
Furthermore, if you don't have any files marked, your current
directory will be set to the newly created directory.

Open window
Opens a new (file manager) window on the current directory, as
configured with 'windowtype' and 'windowcmd' in the .pfmrc. Some
examples:

If 'windowtype' is "pfm" and 'windowcmd' is something like
"xterm -e", then a new terminal window running "pfm" will be
opened.

If 'windowtype' is "standalone" and 'windowcmd' is something like
"nautilus", then a new "nautilus" window will be opened.

Physical path
Shows the physical pathname of the current directory until a key is
pressed.

Read history/bookmarks
Offers the user the choice to read the input history and/or
bookmarks from disk.

The input history is the history of Unix commands, pathnames,
regular expressions, modification times, and file modes that the
user enters. "pfm" uses the readline library to manage these.

The input history is also read in when "pfm" starts, from
individual files in $HOME/.pfm/.

The bookmarks are also read in when "pfm" starts, from
$HOME/.pfm/bookmarks.

See also More-Read history/bookmarks.

F2 Redescend
If the previous directory was a descendant of the current
directory, return one level down. e.g. if the previous directory
was /home/rene/projects/pfm and the current directory is /home,
this command will subsequently descend into /home/rene,
/home/rene/projects and /home/rene/projects/pfm.

F4 Color
Like F4, but cycles backward.

F5 Smart refresh
Refreshes the directory like F5 (remove lost files from the
listing, read the current directory again etc.) but keeps the
marks.

F6 Multilevel sort
Allows the user to enter a string of sort mode characters which
will be applied sequentially. Example: a string of sN will sort by
size ascending followed by name descending; the string tn will sort
directories before files, each sorted alphabetically.

F9 Layout
Like F9, but cycles backward.

@ Starts a perl shell in the context of "pfm". Primarily used for
debugging.

MISCELLANEOUS and FUNCTION KEYS
ENTER
If the current file is a directory, "pfm" will chdir() to that
directory. Otherwise, "pfm" will attempt to launch the file. See
below under "LAUNCHING FILES".

DEL Identical to the Delete command (see above).

! Toggle clobber mode. This controls whether a file should be
overwritten when its name is reused in Copy, Link or Rename.

" Toggle pathname handling. In physical mode, the current directory
path will always be transformed to its canonical form (the simplest
form, with symbolic names resolved). In logical mode, all symbolic
link components in the current directory path will be preserved.

% Toggle show/hide whiteout files.

. Toggle show/hide dot files.

/ Identical to Find (see above).

; Toggle show/hide svn ignored files.

< Pan the menu and footer, in order to view all available commands.

= Cycle through displaying identity information: username, hostname,
and/or ttyname.

> Pan the menu and footer, in order to view all available commands.

? Display help. Identical to F1.

@ Allows the user to enter a perl command to be executed in the
context of "pfm". Primarily used for debugging, but may for example
be used for setting environment variables, e.g.:

$ENV{LC_ALL} = 'C'

F1 Help
Display help, version number and license information.

F2 Previous
chdir() back to the previous directory. In shell commands, the
previous directory path may be referred to as =9.

F3 Redraw
Fit the file list into the current window and refresh the display.

F4 Color
Change the current colorset. Multiple colorsets may be defined, see
the .pfmrc file itself for details.

F5 Refresh
Current directory will be reread. Use this when the contents of the
directory have changed. This command will erase all marks.

F6 Sort
Allows you to re-sort the directory listing. You will be presented
a number of sort modes.

F7 Swap
Alternates the display between two directories. When switching for
the first time, you are prompted for a directory path to show. When
you switch back by pressing F7 again, the contents of the alternate
directory are displayed unchanged. Menu text changes color when in
swap screen. In shell commands, the directory path from the
alternate screen may be referred to as =5. If the 'persistentswap'
option has been set in the config file, then leaving the swap mode
will store the main directory path as swap path again.

F8 In/Exclude
Toggles the mark (include flag) on an individual file.

F9 Layout
Toggle the column layout. Layouts are defined in your .pfmrc, in
the 'defaultlayout' and 'columnlayouts' options. See the config
file itself for information on changing the column layout.

Note that a 'grand total' column in the layout will only be filled
when the siZe command is issued, not when reading the directory
contents.

F10 Multiple
Switch between single-file and multiple-file mode.

F11 Restat
Refresh (using lstat(2)) the displayed file data for the current
file (or files, in multiple mode).

F12 Mouse
Toggle mouse use. See below under "MOUSE COMMANDS".

ESCAPE MODIFIERS
The above mentioned escapes =0 to =9 and =e, =E, =p and =v can make use
of the following modifiers:

={escape#prefix}
={escape##prefix}
prefix is a word which may use * characters as a wildcard. If the
prefix matches the beginning of the value of the escape, then the
result of the expansion is the expanded value of escape with the
shortest (#) or longest (##) matching string deleted.

={escape%suffix}
={escape%%suffix}
suffix is a word which may use * characters as a wildcard. If the
suffix matches a trailing portion of the value of the escape, then
the result of the expansion is the expanded value of escape with
the shortest (%) or longest (%%) matching string deleted.

={escape/string/replacement}
={escape//string/replacement}
Find occurrences of string in the expanded value of escape and
replace them with replacement. For /, replace only the first
occurrence; for //, replace all occurrences.

={escape^letters}
={escape^^letters}
={escape,letters}
={escape,,letters}
This expansion modifies the case of alphabetic characters in
escape. The ^ operator converts letters in letters to uppercase;
the , operator converts letters in letters to lowercase. The ^^
and ,, expansions convert each matched character in the expanded
value; the ^ and , expansions match and convert only the first
character in the expanded value. If letters is omitted, it is
treated like a ?, which matches every letter.

If a modification is done on =8, it is done on each of the expanded
values.

Examples:

──────────────────────────────────────────────────
escape result
──────────────────────────────────────────────────
=2 ActivateDebtor.php
={2} ActivateDebtor.php
={2#Activate} Debtor.php
={2#t} ActivateDebtor.php
={2#*t} ivateDebtor.php
={2##*t} or.php
={2%hp} ActivateDebtor.p
={2%t} ActivateDebtor.php
={2%t*} ActivateDeb
={2%%t*} Ac
={2,d} Activatedebtor.php

={2^ph} ActivateDebtor.Php
={2^^ph} ActivateDebtor.PHP
={2,,t} ActivateDebtor.php
={2^^t} AcTivaTeDebTor.php

={8#User}.bak Id.php.bak Name.php.bak
Local={8/.php/} LocalUserId LocalUserName
──────────────────────────────────────────────────

LAUNCHING FILES
The ENTER key, when used on a non-directory file, will make "pfm"
attempt to launch the file.

"pfm" can be configured to use any combination of four methods for
determining the appropriate command. These methods are:

extension
The filename extension will be translated to a file type
(preferably a MIME type) using the 'extension[*.extension]' options
in the config file.

Example:

extension[*.gif]: image/gif
extension[*.pdf]: application/pdf

Launch commands for every file type may be defined using the
'launch[filetype]' options.

Example:

launch[image/gif] : =v =2 &
launch[application/pdf]: acroread =2 &

magic
The file(1) command will be run on the current file. Its output
will be translated to a file type using the 'magic[regular
expression]' options in the config file.

Example:

magic[GIF image data]: image/gif
magic[PDF document] : application/pdf

The file type will then be used to look up a launch command as
described above.

xbit
The executable bits in the file permissions will be checked (after
symbolic links have been followed). If the current file is
executable, "pfm" will attempt to start the file as an executable
command.

name
Some filenames have their own unique way of launching them. These
can be configured using the 'launchname' config option:

launchname[Makefile] : make
launchname[Imakefile] : xmkmf
launchname[Makefile.PL]: perl =2

To select which method or methods (extension, magic, xbit, and/or name)
should be used for determining the file type, you should specify these
using the 'launchby' option (separated by commas if there is more than
one).

Example:

launchby:name,xbit,extension

"pfm" will try these methods in succession until one succeeds, or all
fail.

If the file type cannot be determined, the current file will be
displayed using your pager.

The ENTER key will always behave as if "pfm" runs in single-file mode.
It will not launch multiple files. Use Your or cOmmand to launch
multiple files.

QUOTING RULES
"pfm" adds an extra layer of parsing to filenames and shell commands.
It is therefore important to take notice of the rules that "pfm" uses.

In versions prior to 1.93.1, the default escape character was \. Since
this causes confusing results, this is no longer the default, and you
are discouraged from using it.

The following six types of input can be distinguished:

a regular expression (only the Include and eXclude commands)
The input is parsed as a regular expression.

a time (e.g. the Time or Include - Before commands)
Characters not in the set "[0-9.]" are removed from the input.

a literal pattern (only the Find command)
The input is taken literally.

not a filename or shell command (e.g. in Attribute or User)
The input is taken literally.

a filename (e.g. in Copy or tarGet).
First of all, tilde expansion is performed.

Next, any "=[0-9eEpv]" character sequence is expanded to the
corresponding value.

At the same time, any "=[^0-9eEpv]" character sequence is just
replaced with the character itself.

Finally, if the filename is to be processed by "pfm", it is taken
literally; if it is to be handed over to a shell, all
metacharacters are replaced escaped.

a shell command (e.g. in cOmmand or Print)
First of all, tilde expansion is performed.

Next, any "=[0-9eEpv]" character sequence is expanded to the
corresponding value, with shell metacharacters escaped.

At the same time, any "=[^0-9eEpv]" character sequence is just
replaced with the character itself.

In short:

· "pfm" always escapes shell metacharacters in expanded =2 etc.
constructs.

· In filenames entered, shell metacharacters are taken literally.

· In shell commands entered, metacharacters that you want to be taken
literally must be escaped one extra time.

Examples:

──────────────────┬─────────────────────────────────────────
char(s) wanted in │ char(s) to type in char(s) to type in
filename │ filename shell command
──────────────────┼─────────────────────────────────────────
any non-metachar │ that char that char
\ │ \ \\ or '\'
" │ " \" or '"'
= │ == ==
space │ space \space or 'space'
filename │ =2 =2
\2 │ \2 \\2 or '\2'
=2 │ ==2 ==2
──────────────────┴─────────────────────────────────────────

MOUSE COMMANDS
When "pfm" is run in an xterm or other terminal (or emulator) that
supports the use of a mouse, turning on mouse mode (either initially
with the 'defaultmousemode' option in the .pfmrc file, or while running
using the F12 key) will give mouse access to the following commands:

─────┬──────────────────────────────────────────────────────────────────
│ location clicked
btn ├──────────────────────────────────────────────────────────────────
│ pathline menu/ heading file- file- dirname
│ footer line name
─────┼──────────────────────────────────────────────────────────────────
1 │ chdir() pfm-cmd sort F8 Show Show
2 │ cOmmand pfm-cmd sort rev Show ENTER More - Open win
3 │ cOmmand pfm-cmd sort rev Show ENTER More - Open win
─────┼──────────────────────────────────────────────────────────────────
up │ five lines up
down │ five lines down
─────┴──────────────────────────────────────────────────────────────────

If the config option 'mouse_moves_cursor' has been set to 'yes', a
mouse click on a non-directory will move the cursor to that file.
Otherwise, the cursor will only move when a directory is clicked or the
mouse wheel is used.

The mouse wheel moves the cursor five lines per notch by default, or
one line if shift is pressed. The actual number of lines can be
configured in your .pfmrc using 'mousewheeljumpsize'.

Clicking button 1 on the current directory path will chdir() up to the
clicked ancestor directory. If the current directory was clicked, or
the device name, it will act like a More - Show command.

Clicking button 2 on a directory name will open a new window like More
- Open window.

Clicking on the column headings will sort the directory contents by
that heading. Clicking again will sort the directory in reverse order.

Clicking on "Sort" in the footer will cycle through a number of
preconfigured sort modes as defined in the config option 'sortcycle'.

Clicking on the menu or footer will execute the command that was
clicked.

Clicking on one of the identity lines in the info column will toggle
the display like the = command does.

Mouse use will be turned off during the execution of commands.

WORKING DIRECTORY INHERITANCE
Upon exit, "pfm" will save its current working directory in the file
$HOME/.pfm/cwd, and its swap directory, if any, in $HOME/.pfm/swd.
This enables the user to have the calling process (shell) "inherit"
"pfm"'s current working directory, and to reinstate the swap directory
upon the next invocation. To achieve this, you may call "pfm" using a
function or alias like the following:

Example for ksh(1), bash(1) and zsh(1):

pfm() {
if [ -s ~/.pfm/swd ]; then
swd=-s"`cat ~/.pfm/swd`"
fi
# providing $swd is optional
env pfm $swd "$@"
if [ -s ~/.pfm/cwd ]; then
cd "`cat ~/.pfm/cwd`"
rm -f ~/.pfm/cwd
fi
}

Example for csh(1) and tcsh(1):

alias pfm ': \
if (-s ~/.pfm/swd) then \
set swd=-s"`cat ~/.pfm/swd`" \
endif \
: providing $swd is optional \
env pfm $swd \!* \
if (-s ~/.pfm/cwd) then \
cd "`cat ~/.pfm/cwd`" \
rm -f ~/.pfm/cwd \
endif'

ENVIRONMENT
ANSI_COLORS_DISABLED
Detected as an indication that ANSI coloring escape sequences
should not be used.

CDPATH
A colon-separated list of directories specifying the search path
when changing directories. There is always an implicit . entry at
the start of this search path.

DISPLAY
The X display on which the 'windowcmd' will be opened.

EDITOR
The editor to be used for the Edit command. Overridden by VISUAL.

LC_ALL
LC_COLLATE
LC_CTYPE
LC_MESSAGES
LC_NUMERIC
LC_TIME
LANG
Determine locale settings, most notably for collation sequence,
messages and date/time format. See locale(7).

PAGER
Identifies the pager with which to view text files. Defaults to
less(1) for Linux systems or more(1) for Unix systems.

PERL_RL
Indicate whether and how the readline prompts should be
highlighted. See Term::ReadLine(3pm). If unset, a good guess is
made based on your config file 'framecolors[]' setting.

PFMRC
Specify a location of an alternate .pfmrc file. If unset, the
default location $HOME/.pfm/.pfmrc is used. The cwd- and history-
files cannot be displaced in this manner, and will always be
located in the directory $HOME/.pfm/.

PRINTER
May be used to specify a printer to print to using the Print
command.

SHELL
Your default login shell, spawned by More - sHell.

VISUAL
The editor to be used for the Edit command. Overrides EDITOR.

FILES
The directory $HOME/.pfm/ and files therein. A number of input
histories and the current working directory on exit are saved to this
directory.

The default location for the config file is $HOME/.pfm/.pfmrc.

EXIT STATUS
0 Success (could also be a user requested exit, e.g. after --help or
--version).

1 Invalid commandline option.

2 No valid layout found in the .pfmrc file.

DIAGNOSIS
If "pfm" reports that your config file might be outdated, you might be
missing some of the newer configuration options (or default values for
these). The best way to solve this is by having "pfm" generate a new
config file, e.g. by running the following command and comparing the
new config file with your original one:

env PFMRC=~/.pfm/.pfmrc-new pfm

Alternatively, you may reply with y when "pfm" offers to update the
config file for you.

If a function key like F1 or F10 is intercepted by your windowing
system or OS, and it is not feasible to change that mapping, then you
can define an alternative key mapping (like Shift-F1, Shift-F10) in
your .pfmrc, e.g.:

keydef[*]:k1=\eO1;2P:k10=\e[21;2~:

Or for a specific value of TERM:

keydef[xterm]:k1=\eO1;2P:k10=\e[21;2~:

BUGS and WARNINGS
The smallest terminal size supported is 80x24. The display will be
messed up if you resize your terminal window to a smaller size, unless
you specify 'force_minimum_size' in the config file and the terminal
supports resizing; in that case "pfm" will resize the terminal to at
least 80 columns and/or 24 rows.

The author once almost pressed ENTER when logged in as root and with
the cursor on the file /sbin/reboot. You have been warned.
