Yu Watanabe	0dc0bf4caf	profile: replace default bash prompt with more informative one ... The default bash PS1 provides mostly no information. Let's replace it. Before: ``` [watanabe@thinkpad-x280:~] $ run0 🦸 bash-5.2# echo $PS1 🦸 \s-\v\$ ``` After: ``` [watanabe@thinkpad-x280:~] $ run0 🦸 [root@thinkpad-x280 watanabe]# echo $PS1 🦸 [\u@\h \W]\$ ``` Fixes #38494.	2025-08-06 14:24:19 +01:00
Tobias Klauser	12e33d332b	profile.d: don't bail if $SHELL_* variables are unset ... If - for whatever reason - a script uses set -u (nounset) and includes /etc/profile.d/70-systemd-shell-extra.sh (e.g. transitively via /etc/profile) the script would fail with: /etc/profile.d/70-systemd-shell-extra.sh: line 15: SHELL_PROMPT_PREFIX: unbound variable For example: $ cat > foo.sh <<EOF #!/bin/sh set -u source /etc/profile EOF $ chmod 700 foo.sh $ ./foo.sh /etc/profile.d/70-systemd-shell-extra.sh: line 15: SHELL_PROMPT_PREFIX: unbound variable Fix this by using shell parameter substitution[^1] (which is a POSIX shell concept) to set the $SHELL_* variables to the empty string if undefined.
