xless - File browsing program for the X Window System.
SYNOPSIS
xless [-f] [-toolkitoption ...] [filename ...]

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 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

normal command line options (as described in X(1). It also supports:

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 number
of this xless executable.

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
environment 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
directories 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
'geometry'.
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.
