bsetbg(1) v2.0 bsetbg(1)NAMEbsetbg - utility to manipulate the appearance of the X11
desktop's root window.
SYNOPSISbsetbg [options] image
DESCRIPTIONbsetbg is intended to provide a standard method for the
Blackbox window manager to alter the background of the
root window (although it will work with any other window
manager as well). bsetbg acts as a wrapper both to bset_
root and to a flexible variety of third-party applications
that it uses when handling images files.
OPTIONS-f, -full image
image is stretched to fill the entire desktop.
-t, -tile image
image is tiled on the desktop.
-c, -center image
image is centered on the desktop.
-e, -exec program options fallback-arg image
This option tells bsetbg to run a separate command
by executing program with options, where options
are arguments to program.
If a fallback-arg is supplied (-full, -tile, or
-center as described above), bsetbg will assume
that the last argument is a filename. In the case
that program exits non-zero or isn't available on
the target system, bsetbg will try to handle the
file with the fallback argument.
See the EXAMPLES section for more information on
-exec.
-p, -post list
Specifies a list of arguments to pass to the
$POST_COMMAND.
-d, -debug
Debugging mode. bsetbg will print commands without
executing them.
-g, -generate list
Output a list of default configuration values,
suitable for redirecting into ~/.bsetbgrc. Any
arguments that are supplied will be considered
applications to search for in the system path,
overriding bsetbg's internal defaults.
-app imageApp
Use this flag to specify which image application to
use. This application may be one of the pre-defined
list or any application capable of displaying an
image on the root window. This flag may be used in
conjunction with passing application specific
parameters to the application, in which case they
should be enclosed in double quotes.
-v, -version
Output version number.
-h, -help
Output a brief usage message.
OTHER OPTIONSbsetbg will also accept all of the arguments for bsetroot.
Consult the bsetroot(1) man page for further information.
CONFIGURATIONbsetbg will read its configuration values from the file
~/.bsetbgrc if it exists. Otherwise, it will scan the sys
tem path for a pre-defined list of image applications to
use (currently this list consists of qiv, xli, xv,
wmsetbg, Esetroot, display, and xsetbg).
~/.bsetbgrc should contain the following variables:
CENTER="string"
Application and arguments to be used to center an
image on the root window when the -center argument
is specified.
FULL="string"
Application and arguments to be used to stretch an
image to fill the root window when the -full argu
ment is specified.
TILE="string"
Application and arguments to be used to tile an
image on the root window when the -tile argument is
specified.
DEFAULT="string"
Action to take place by default if none of the
above have been specified.
The following variables are optional:
NO_EXEC="boolean"
If this variable is set, bsetbg will never modify
the root window.
POST_COMMAND="string"
This variable specifies a command that bsetbg will
run after every successful modification of the root
window.
LOG_LAST_CMD="boolean"
If this variable is set, bsetbg will keep a logfile
of the last two successful commands.
LOGFILE="string"
This variable can specify the logfile to be used
when $LOG_LAST_CMD is defined. The default is
~/.bsetbg_last_cmd .
As mentioned above, bsetbg will function perfectly for the
majority of users without having a configuration file.
Power users who want more control over bsetbg's behavior
should run bsetbg-g and use the output to create a
~/.bsetbgrc which may then be tweaked by hand.
EXAMPLES
In this example, bsetbg will set the image in centered
mode:
bsetbg-center foo.png
An example of the -exec argument:
bsetbg-exec xv -root -quit -rmode 5 -rbg rgb:2/2/2 \
-center foo.png
An example in which bsetbg creates a configuration file
using xv and qiv:
bsetbg-g xv qiv > ~/.bsetbgrc
An example of the use of the -app argument:
bsetbg-app qiv "-o rgb:d6/c5/a2 -x" -c foo.png
