bsetbg(1)                            v2.0                            bsetbg(1)

NAME
       bsetbg - utility to manipulate the appearance of the X11 desktop's root
       window.

SYNOPSIS
       bsetbg [options] image

DESCRIPTION
       bsetbg 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 bsetroot 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 OPTIONS
       bsetbg will also accept all of the arguments for bsetroot.  Consult the
       bsetroot(1) man page for further information.

CONFIGURATION
       bsetbg will read its configuration values from the file ~/.bsetbgrc if
       it exists. Otherwise, it will scan the system 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 argument 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
