Xless(1)Xless(1)NAMExless - File browsing program for the X Window System.
SYNOPSISxless [-f] [-toolkitoption ...] [filename ...]
DESCRIPTION
Xless pops up a window on the display specified, containing the file
specified on the command line or piped in from stdin. This file may
easily be viewed using the scrollbar to the left of the window. Xless
also takes input from the standard input. Extra function are available
on the toolbox to the right of the window:
- Pop up a help window.
- Search a specified pattern
- Search the next occurance of the above specified pattern
- Open a session of the editor (specified in the environment variable
EDITOR) on the current file
- Reload the current file
- Change file in the current window
- Open a new xless window to display the specified file
- Print the current file
- Close the current window
For further information on using xless please read the online help
information. The rest of this manual page will discuss customization
of xless to suit the needs of a particular user.
OPTIONS
Xless is build upon the X Toolkit (Xt) and as such understands all the
normal command line options (as described in X(1). It also supports:
-follow
Continually check the file for new input (so that xless behaves
like tail -f).
-f Alias for -f.
-help Print a list of valid options. -version Print the version num‐
ber of this xless executable.
WIDGET AND RESOURCE NAMES
In addition to the usual widget resources, Xless has the following
application resources:
standardFont
The default font to be used if any of the specified fonts are
available.
textFont The fonts to use for the text.
labelFont The fonts to use for labels in dialog boxes.
buttonFont
The fonts to use for labels on buttons.
standardCur
The cursors to use in the main button window with the Quit
and Help commands.
dialogCur The cursors to use in the toolbox and dialog box windows.
helpFile Name of a file to use instead of the system default helpfile.
editor Name of editor to invoke (if neither VISUAL nor EDITOR envi‐
ronment variable is set)
editorDoesWindows
Set to TRUE if your editor brings up its own window (xedit or
GNU emacs, for example.)
printCommand
Command string used to print the current file. The name of
the file is simply appended to this string. (enscript -G is
nice, if you've got it.)
maxWindows
Maximum number of windows which xless will display at one
time. Set this to zero if you don't want a limit. (This is
a good thing to set if you tend to run xless * in direc‐
tories with lots of files.)
quitButton
Set to TRUE if you want a Quit button on every window which,
when clicked, will quit every window started from this copy
of xless. The default is FALSE.
sizeToFit Set to TRUE if you want text windows to be only as big as
they need to be, up to the maximum size specified by 'geome‐
try'.
removePath
Set to TRUE if you want the directory portion of the file
path removed. For example, a path like
/usr/src/X11/xless/main.c would be shortened to main.c. The
default is TRUE.
defaultSearchType
Default method used to search the text (invoked from the
Search button). Possible values are ExactMatch (which is the
default), CaseInsensitive and RegularExpression.
monitorFile
Set to TRUE if you want the file to be continually checked
for new input (so that xless behaves like tail -f). The
default is FALSE.
COLOR RESOURCES
If you have a color display and you're running at least X11R5, you may
want to add a line like:
#ifdef COLOR
*customization: -color
#endif
to your personal resources file. This will allow you to get the color-
related resources for not only xless, but for every program which sets
up its own color resources.
Versions of X earlier than X11R5 don't support the customization
resource. If you're on one of those, you'll have to include the color
resources in your personal resources file.
