My thin wrapper for emerge(1)

I’ve recently written a thin wrapper over emerge that I use in my development environment. It does the following:

1. set tmux pane title to the first package argument (so you can roughly see what’s emerging on every pane)
2. beep meaningfully when emerge finishes (two beeps for success, three for failure),
3. run pip check after successful run to check for mismatched Python dependencies.

Here’s the code:

#!/bin/sh

for arg; do
	case ${arg} in
		-*)
			;;
		*)
			tmux rename-window "${arg}"
			break
			;;
	esac
done

/usr/bin/emerge "${@}"
ret=${?}

if [ "${ret}" -eq 0 ]; then
	python3.11 -m pip check | grep -v certifi
else
	tput bel
	sleep 0.1
fi

tput bel
sleep 0.1
tput bel

exit "${ret}"
