Package: bash-completion
Version: 1:2.1-4
Severity: normal
Dear Maintainer,
For my root .bashrc i have the following introduction block that is designed to
help ensure i don't inherit bad/unexpected values from somewhere else (sshd,
/etc/profile.d/, etc...) and the root interactive bash environment is as close
to pristine/expected and built on from there.
\unset -f unalias ; \unalias -a ; \unset -f command
\unset LD_LIBRARY_PATH LD_PRELOAD SHELLOPTS CDPATH HISTFILE HOSTFILE
INPUTRC 2>/dev/null
confpath="$(command -p getconf PATH 2>/dev/null)"
export PATH="/opt/sbin:/opt/bin:/sbin:/usr/sbin:${confpath:-/bin:/usr/bin}"
\type typeset >/dev/null && \unset -f $(\typeset -f | \grep '()' | \cut -d'
' -f1)
However, because the bash completions package defines a bunch of functions
(that i'm removing above), i would like to be able to subsequently re-evaluate
the bash completions later on in the .bashrc after this block.
but, /etc/profile.d/bash_completions.sh has the following conditional:
# Check for interactive bash and that we haven't already been sourced.
if [ -n "$BASH_VERSION" -a -n "$PS1" -a -z "$BASH_COMPLETION_COMPAT_DIR" ];
then
Since
/usr/share/bash-completion/bash_completion
establishes BASH_COMPLETION_COMPAT_DIR as a readonly variable, i can not unset
it in the shell, and thus can not re-source this script.
I presume it's readonly for security reasons (so it couldn't be hijacked to run
random code in another location?)
So, with that in mind, could the conditional be changed instead to something
like:
if [ -n "$BASH_VERSION" -a -n "$PS1" -a \( -z
"$BASH_COMPLETION_COMPAT_DIR" -o \( "$1" = "force" \) \) ]; then
so that it could be forcibly re-evaluated? (this way i don't have to duplicate
its code in my .bashrc and hope it doesn't change on package updates)
Alternative solutions welcome.
thanks,
