Package: bash
Version: 4.2-2
Severity: wishlist

As described at http://yeupou.wordpress.com/2012/05/29/having-homemade-aliases-functions-and-such-available-to-every-interactive-shells/ I find frustrating to be unable by default to add local shell aliases/functions to be automatically sourced for any interactive bash shell.

This mechanism exists for *login* interactive shells (/etc/profile.d) and is actually even used by bash-completion. I found no conclusive reason not to provide similar possibility for non-login shells that are probably the most common on a X session through xterms.

Reading bug #275623, I doubt that any change in this regard will occurs on base-files.

I think it would be really nice to be forced to edit by hand /etc/bash.bashrc to achieve the simple addition of local functions/aliases/etc.
It's a no-go to edit /etc/skel/, as far I understand that won't make for site-wide functions/aliases but copied-once files that will easily get outdated.
It's also a no-go to botch /etc/profile supposed behavior (run-once at login only) to get it called by /etc/bash.bashrc.

thanks

This is required for fixing http://bugs.debian.org/678174
“bash-completion: /etc/profile.d/bash_completion.sh does not work for
non-login shells (e.g., screen, xterm)”.

It’s also something we needed in the MIT Debathena project. We currently
work around this by ‘dpkg-divert’ing /etc/bash.bashrc, which is horrible.

Hello,

More and more packages are adding files to /etc/profile.d/ but nothing
is sourcing them by default in debian.

$ apt-file search /etc/profile.d/|wc -l
23

Other distributions (RH-like) are sourcing files put in that directory
for years now (but not /etc/profile itself)

From /etc/bashrc:

# Only display echos from profile.d scripts if we are no login shell
# and interactive - otherwise just process them to set envvars
for i in /etc/profile.d/*.sh; do
if [ -r "$i" ]; then
if [ "$PS1" ]; then
. "$i"
else
. "$i" >/dev/null
fi
fi
done

Wouldn't it make sense to follow what RH and already some packages in
the archive are doing and source .sh files from /etc/profile.d/ in
non-login shell as well?

Kind regards,

Laurent Bigonville

I just had to resort to modifying /etc/bash.bashrc which is really ugly IMHO.

Is there anything I can do to make this functionality sane in Debian?

Kind regards,

Hey.

Anything new on this? :D

It's probably not that important anymore nowadays... VTE works without
it's shell file being sourced[0], but still:

Most files in /etc/profile.d/ seems to actually rather belong to bash
and interactive shells (and thus rather the .bashrc family than the
.profile family).

I also don't think anything will come forward from LSB or freedesktop
side - and to me, it also doesn't seem to be their business.

.bashrc-like files are quite clearly bash's domain (unlike .profile
which is shared by several sh-like shells), so if at all it would be
bash's duty to "standardise" this.


So are there still any technical reasons against shipping a
/etc/bash.bashrc.d/ (and inviting other packages to use that)?

Perhaps I wouldn't even source it from /etc/bash.bashrc but leave that
up to the user's .bashrc.

But at least it would be a better place for these shell snippets than
/etc/profile.d.



Cheers,
Chris.


[0] Well the behaviour is actually still a bit different, cause the
shell script uses the terminal's OSC 7 command (which IMO has anyway
some minor/subtle security issue), e.g. it would pick up the path for
sub-shells/screens/etc. running in the terminal.
