DESCRIPTION
Xcmd is a front-end for starting programs under X11. You can tell xcmd
to look for a window with a specific class, resource name, or title
string (using the --find-property options); if it finds one or more,
xcmd will `raise' them, otherwise it will run the command you specify.
You can tell xcmd to run commands that create their own windows (using
--xcmd), or to run commands inside a terminal window (using --cmd) with
various options.
OPTIONS-h or --help
Display version information and a summary of command syntax.
-d or --display display
This option allows you to specify the server to connect to; see
X(3x).
-c or --cmd command
Run command in a terminal window (see Terminal Window Options
below). If you use one of the --find-property options, xcmd
only runs command if it can't find a window with that property.
-x or --xcmd command
Run command, with the expectation that it will create its own
window. If you use one of the --find-property options, xcmd
only runs command if it can't find a window with that property.
Find Options
The following options tell xcmd to search the display for a window that
has the specified property. If xcmd finds one or more such windows, it
raises them to the top of the display. These options are mutually
exclusive.
-fc or --find-class window-class
Find windows whose class matches window-class exactly.
-fr or --find-resource window-resource
Find windows whose resource name matches window-resource
exactly.
-fs or --find-substr title-substring
Find windows whose title contains the string title-substring.
-ft or --find-title window-title
Find windows whose title matches window-title exactly.
-ir or --iconify-and-raise
When xcmd finds a window, first iconify it, then raise it; this
`flashes' a little, but it works reliably under FVWM with dif‐
ferent X server loads. It doesn't work reliably with Window‐
Maker.
-or or --only-raise
When xcmd finds a window, just raise it. This doesn't `flash',
but it also doesn't always work with FVWM. It does work reli‐
ably with WindowMaker, as long as the window is in the current
workspace. This is the default.
Terminal Window Options
The following options control the appearance of the terminal window
created when you run a command with --cmd. Xcmd gives an error if you
use any of these options without using --cmd.
-t or --title window-title
The title to give the terminal window. If you don't specify
this option, the title reverts to the resource name (see --name)
if one is specified, otherwise it reverts to command.
-i or --icon icon-title
The title to give to the terminal window when it's iconified.
If you don't specify this option, the icon title reverts to the
window title.
-n or --name window-resource
The resource name to give the terminal window. If you don't
specify this option, it reverts to the default resource name for
the terminal program (e.g., `xterm' for xterm(1x)).
-g or --geometry window-geometry
The geometry to use for the terminal window. If you don't spec‐
ify this option, it reverts to the default for the terminal pro‐
gram.
-o or --opt additional-options
Additional options to pass to the terminal program; additional-
options should be one argument---you may need to quote it using
your favorite shell's regular syntax.
-s/+s or --scroll/+scroll
Use (--scroll) or don't use (+scroll) a scrollbar in the termi‐
nal window. If you don't specify either of these options,
whether the terminal uses a scrollbar depends on its defaults
and its X resource settings.
-rt/-xt or --rxvt/--xterm
Use rxvt(1x) or xterm(1x) as the terminal program to run command
in. Normally, xcmd uses the terminal program specified in the
XCMD_TERM environment variable (see ENVIRONMENT below), or
xterm(1x) if that variable is not set. These options override
the default setting.
EXAMPLES
Here are some examples of how to use xcmd:
xcmd--cmd vi
Run vi in a terminal window.
xcmd--cmd 'vi ~/.Xdefaults'
Run vi in a terminal window and edit ~/.Xdefaults.
xcmd--find-resource 'Navigator' --xcmd netscape
Look for a Netscape window, or start one if none found.
xcmd--find-title 'Network Configurator' --xcmd 'sudo netcfg'
Look for a window titled Network Configurator; if none found,
use sudo to start netcfg.
xcmd--find-title Mail --cmd pine --title Mail --name xMail +scroll
Look for a window titled Mail; if none found, start pine in a
terminal window titled Mail, with a resource name of xMail and
no scrollbar. If the X resource `*xMail*vt100.geometry: 80x40'
is set, for instance, the resulting window will be 80 columns
wide by 40 lines high.
NOTES
Xcmd uses an execl(3) call to run /bin/sh -c exec command, so that com‐
mand inherits xcmd's process ID. Xcmd runs in the foreground by
default; use your favorite shell's regular syntax to start xcmd in the
background (e.g., `xcmd --find-title vi --cmd vi &' for Bourne-compati‐
ble shells).
ENVIRONMENT
DISPLAY
To get the default host and display number.
XCMD_TERM
To set the default terminal program to use with --cmd. Overrid‐
den by the command line.
XCMD_ICONIFY
If set to `0', `no', or `false', act as if the command-line
option --only-raise was specified (this is the default if not
set). If set to `1', `yes', or `true', act as if the command-
line option --iconify-and-raise was specified. Any other value
produces an error message. XCMD_ICONIFY is overridden by the
command line.

Xcmd is very loosely derived from portions of xwit by Mark Martin and
David DiGiacomo and xwininfo by Mark Lillibridge. Almost none of the
original code remains.
