=== Check welche Shell benutzt wird ===
<code>
[[ $- == *i* ]] && echo 'Interactive' || echo 'Not interactive'

shopt -q login_shell && echo 'Login shell' || echo 'Not login shell'
</code>

Direkt an Console anmelden und X11 starten --> interactive, non-login shell\\
Per ssh an melden --> interactive, login shell
