Eliminate from dmenu the programs that cannot be launched

Question

I use i3 with dmenu. Is it possible to prevent from showing up the programs that cannot be launched via dmenu? (e.g. top, ps, ls etc...)

Answer 1

You can modify dmenu_run to exclude an application from appearing in dmenu. For example, to exclude a2x, add an additional process to the pipeline:

From:

#!/bin/sh
dmenu_path | dmenu "$@" | ${SHELL:-"/bin/sh"} &

To:

#!/bin/sh
dmenu_path | awk '!/a2x/' | dmenu "$@" | ${SHELL:-"/bin/sh"} &

If you wanted to exclude more than one application, you could use an excludes file:

dmenu_path | grep -v -f /path/to/dmenu_excludes | dmenu "$@" | ${SHELL:-"/bin/sh"} &
