Package: bash Version: 5.2.15-2+b1 Severity: normal Tags: patch Dear Maintainer,
When running the man-pages linters with 2>&1 | less, I got a wall of
/etc/bash.bashrc: line 7: PS1: unbound variable
It uses
SHELL := /usr/bin/env bash -Eeuo pipefail
and, /etc/bash.bashrc says, ll. 7,8:
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
I've fixed this by making that expansion ${PS1-} instead;
this is what debian_chroot does below, for presumably the same reason.
I've preventatively done the same thing to the rest of the variables,
but just the PS1 thing was enough to run the tests.
I'm attaching a diff of the unpacked source
(incl. a $(cat => $(<; this a free optimisation in bash-specific code);
this would be much easier if the VCS pointed at anything (#1024158).
Best,
наб
