An application launcher with fuzzy search via fzy (fzf would also work)

fuzzy_run

#!/usr/bin/env bash

# Requirements: bash, coreutils, fzy, xdotool, xterm.
#
# Position and decorations can be set in i3 with something like:
# for_window [class="^FuzzyRun"] floating enable border none move position center
#
# Either `-fullscreen', or `-geometry' should be used. With both in place,
# `-fullscreen' takes precedence.

xdotool search --class FuzzyRun windowactivate ||
exec xterm -class FuzzyRun \
    -fullscreen -geometry "50x45+-9+0" -fa "TerminessTTF Nerd Font Mono" \
    -bg black -bd black -fg gray -bw 0 -b 0 +sb -ls -title "" \
    -e bash -c 'exec nohup "$(compgen -c|sort -u|fzy -p "run >> " -l 100)" </dev/null >/dev/null' &

Brilliant; thank you.
