QCMD(1) QCMD(1)
NAME
qmv, qcp - Rename or copy files quickly, editing the file names in a
text editor
SYNOPSIS
qcp [OPTION]... [FILE]...
qmv [OPTION]... [FILE]...
qcmd --command=COMMAND [OPTION]... [FILE]...
DESCRIPTION
This manual page document describes the qcp, qmv and qcmd commands.
The qmv program allows files to be renamed by editing their names in
any text editor. By changing a letter in a text document, a letter in a
filename can be changed. Since the files are listed after each other,
common changes can be made more quickly.
The qcp program works like qmv, but copies files instead of moving
them.
The qmv program was built with safety in mind - bogus renames caused by
human error are avoided by performing as many checks as possible.
Because of this, qmv supports an interactive mode where each step in
the rename procedure can be executed manually. The default is to start
qmv in non-interactive mode. However, when there is a conflict or
error, qmv will drop to interactive mode (instead of losing all user-
made changes). For more information on the renaming process and inter‐
active mode, see below. This also applies to qcp.
The qcmd program works just like qmv and qcp but allows you to specify
which command to execute.
The ls(1) program is used to list files to rename or copy. Therefore
qmv, qcp, and qcmd accepts some ls options.
RENAMING/COPYING PROCESS
The process of renaming or copying files consists of many steps. They
are:
List files
Generate a list files to rename from command-line arguments by
using ls(1).
Create an editable text file
The edit format creates an editable text file with the file
names.
Start the editor
Start the text editor and wait until the user has finished edit‐
ing it.
Read the edited text file
The edit format reads the edited text file now with updated file
names.
Check rename and reorder to resolve conflicts (qmv only)
This is a complicated step which involves the following tasks:
Tag renames where the destination file already exists, renames
where the old file is now missing or inaccessible, and renames
renames where the new name was not changed. Perform a topologic
sort on the renames, so that renaming b->c, a->b is possible.
Resolve cross references by renaming into temporary names, so
that renaming e->f, f->e (or e->f, f->g, g->e and so on) is pos‐
sible.
This step results in a plan of renames.
Display the plan.
Display the plan to the user.
Apply the plan.
Apply the plan by actually renaming or copying files (unless
--dummy was specified).
If an error occurs during any of the above steps (except the first),
qmv/qcp drops the user into the interactive mode. This way no changes
should be lost, and errors can be corrected manually before continuing.
See below for a description of the interactive mode.
OPTIONS
These programs follow the usual GNU command line syntax, with long
options starting with two dashes (`-').
-a, --all
(Passed to ls.) Do not hide entries starting with `.'.
-A, --almost-all
(Passed to ls.) Do not list implied `.' and `..'.
-B, --ignore-backups
(Passed to ls.) Do not list implied entries ending with `~'.
-c (Passed to ls.) Sort by ctime (time of last modification).
--command=COMMAND
Execute COMMAND instead of mv or cp.
-d, --directory
(Passed to ls.) List directory entires instead of contents.
-r, --reverse
(Passed to ls.) Reverse order while sorting.
-R, --recursive
(Passed to ls.) List subdirectories recursively.
-S (Passed to ls.) Sort by file size.
--sort=WORD
(Passed to ls.) Sort by extension (-X), none (-U), size (-S),
time (-t), version (-v), status (-c), time (-t), atime (-u), or
access (-u).
--time=WORD
(Passed to ls.) If sorting is done by time (--sort=time), sort
by atime, access, use, ctime or status time.
-t (Passed to ls.) Sort by modification time.
-u (Passed to ls.) Sort by access time.
-U (Passed to ls.) Do not sort; list entries in directory order.
-X (Passed to ls.) Sort alphabetically by entry extension.
-f, --format=FORMAT
Change edit format of text file. See below for possible values.
-o, --options=OPTIONS
Pass options to the selected edit format. OPTIONS is in the for‐
mat
OPTION[=VALUE][,OPTION[=VALUE]...]
For a list of available options for each format, use
--options=help or see below.
-i, --interactive
Start in command mode (see below for information on this mode).
-e, --editor=PROGRAM
Specify program to edit text file with. The default program is
determined by looking at the VISUAL environment variable, or if
that is not set, the EDITOR environment variable. If that is not
set either, use the program called editor.
--ls=PROGRAM
Specify path of the ls program. If you omit the directory, the
executable will be searched for in the directories specified by
the PATH environment variable.
-v, --verbose
Be more verbose about what is being done.
--dummy
Do everything as usually, except actually renaming any files
("dummy" mode).
--help Show summary of options.
--version
Output version information and exit.
EDIT FORMATS
An edit format is responsible for generating a text file for editing,
and parsing it once it has been edited. The default format is dual-col‐
umn, but there are other formats as well.
Not all edit formats take the same options. Therefore, it is necessary
to specify them using the --options (-o) option. This option takes a
list of "suboptions" similar to the -o option in mount(8).
Available edit formats are `single-column' (or `sc'), `dual-column' (or
`dc'), and `destination-only' (or `do'). The default format is dual-
column.
DUAL-COLUMN FORMAT
The dual-column format (`dual-column' or `dc') displays files in two
columns. This is the default and recommended format. The leftmost col‐
umn is usually the source file name (which should not be edited), and
the rightmost column the destination file name.
Supported options:
swap Swap location of old and new names when editing. I.e. the left‐
most column is now the destination file name, and the rightmost
the source file name.
separate
Put a blank line between all renames.
tabsize=SIZE
By default, tab characters of size 8 are used to separate the
columns. With this option the width of these tab characters can
be changed.
spaces Use space characters instead of tab characters when indenting.
width=WIDTH
This option specifies the character position (horizontally)
which the second file name starts at.
autowidth
Normally, if the source file name is longer than width charac‐
ters, the destination name is printed on the next line instead.
With this option enabled however, qmv/qcp will adjust the width
so that source and destination file names can be displayed on
one line.
If a width has been specified with width prior to autowidth,
that width will be used as a minimum width.
Example: Assume that width=10,autowidth is specified. Even if
all source file names are shorter than five characters, the
split width would be 10. If there had been one file name longer
than 10 characters, the final width would have been more than 10
characters.
This option is enabled by default.
indicator1=TEXT
Text to put before the first file name (column).
indicator2=TEXT
Text to put before the second file name (column).
help Show summary of edit format options.
SINGLE-COLUMN FORMAT
The single-column format (`single-column' or `sc') displays files in a
single column - first source file name and on the next line the desti‐
nation file name.
Supported options:
swap Swap location of old and new names when editing. I.e. the first
line will contain the destination file name, and the next line
the source file name.
separate
Put a blank line between all renames.
indicator1=TEXT
Text to put before the first file name.
indicator2=TEXT
Text to put before the second file name.
help Show summary of edit format options.
DESTINATION-ONLY FORMAT
The destination-only format (`destination-only' or `do') displays files
only the destination file name, one on each line. This format is gener‐
ally not recommended, since the only way to identify source file name
is by looking at the line number. But it may be useful with some text
editors.
Supported options:
separate
Put a blank line between all renames (file names).
INTERACTIVE MODE
In interactive mode qmv/qcp reads commands from the keyboard, parses
them, and executes them. This is done using GNU readline.
The following commands are available:
ls, list [OPTIONS].. [FILES]..
Select files to rename. If no files are specified, select all
files in current directory. The accepted options are those which
are passed to ls(1). Use `help ls' to display a list of these.
import FILE
Read files to rename from a text file. Each line should corre‐
spond to an existing file to rename.
ed, edit
Edit renames in a text editor. If this command has been run
before, and not `all' is specified, only edit renames with
errors.
plan Display the current rename-plan. (This plan is created after
`edit'.)
apply Apply the current plan, i.e. rename files. Only those files
marked as OK in the plan will be renamed.
retry If some rename failed earlier during `apply', this command will
try those renames again.
show Display the value of the specified configuration variable, or
all variables if none specified. See below for a list of config‐
uration variables.
set VARIABLE VALUE
Set the value of a configuration variable.
exit, quit
Exit the program. If there are unapplied changes, the user will
be notified so, and it will be necessary to run this command an
extra time to exit the program.
help [ls|usage]
If `ls' is specified, display list options. If `usage' is speci‐
fied, display accepted command line options. Otherwise display
help on commands in interactive mode.
version
Display version information.
VARIABLES
The following variables are available in interactive mode:
dummy BOOLEAN
editor STRING
format STRING
options STRING
These variables corresponds to the options with the same name.
tempfile STRING
This variable contains the name of the temporary file which is
edited with `edit'. It cannot be set; only be read with `show'.
A boolean value is specified as `0', `false', `no', `off' or `1',
`true', `yes', and `on'. Strings are specified without quotes.
EXAMPLES
Edit names of files in current directory.
qmv
Edit names of files with extension `.c'. Sort files by modification
time.
qmv -t *.c
Edit names of files using the nedit editor and with column width 100.
qmv -enedit -owidth=100
