To use the programs, download them and make them executable:

chmod a+x downloaded-file

To use multiple programs, create a shell script, e.g. ~/.cmus/status_display_program.sh, that starts all wanted programs:

#!/bin/sh
program1 "$@" &
program2 "$@" &

Then in cmus, set the display_status_program variable to the path of the program or wrapper script:

:set status_display_program=/home/user/.cmus/status_display_program.sh
