swaybg(1)
# NAME
swaybg - Background for Wayland
# SYNOPSIS
*swaybg* [options...]
Displays a background image on all outputs of your Wayland session.
Without an output specified, appearance options apply to all outputs.
Per-output appearance options can be set by passing _-o, --output_ followed by
these options.
# OPTIONS
*-c, --color* <rrggbb[aa]>
Set the background color.
*-h, --help*
Show help message and quit.
*-i, --image* <path>
Set the background image.
*-m, --mode* <mode>
Scaling mode for images: _stretch_, _fill_, _fit_, _center_, or _tile_. Use
the additional mode _solid\_color_ to display only the background color,
even if a background image is specified.
*-o, --output* <name>
Select an output to configure. Subsequent appearance options will only
apply to this output. The special value _\*_ selects all outputs.
*-v, --version*
Show the version number and quit.
