NAME¶
xless - File browsing program for the X Window System.
SYNOPSIS¶
xless [-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 number of this xless executable.
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 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.
