Usage:

• gnome-bg-changer [options] [background.xml file]

gnome-bg-changer is a utility to automatically change the GNOME desktop backgrounds.

The default delay is 5 minutes. If both MINUTES and SECONDS are specified, they are added together.

gnome-bg-changer uses ~/.gnome2/backgrounds.xml as the default background.xml file. This is the file used by the GNOME Appearance Properties, so you can continue to use that to configure your backgrounds. gnome-bg-changer will detect when the file changed and will re-parse it.

Options:

• --version: show program's version number and exit
• -h, --help: show this help message and exit
• -m MINUTES, --minutes=MINUTES: Minutes between background change
• -s SECONDS, --seconds=SECONDS: Seconds between background change
• -r, --random: Change backgrounds randomly
• -v, --verbose: Print extra information
