Bash Version: 4.1
Patch Level: 5
Release Status: release
Description:
Debian's bash (compiled with -DSYS_BASHRC) documentation says
"--rcfile file: Execute commands from file instead of the system wide
initialization
file /etc/bash.bashrc and the standard personal initialization file
~/.bashrc
if the shell is interactive."
But testing shows that /etc/bash.bashrc is being executed even when
--rcfile is used.
So the only way for the user to disable the system-wide rc is to use
the --norc option,
which also disables both ~/.bashrc and any custom rc specified in
--rcfile
User should be able to prevent system rc and selecting a custom rc by
using the --rcfile option,
as per the documentation.
Repeat-By:
from any terminal:
$ sudo echo "echo systemrc" > /etc/bash.bashrc
$ echo "echo customrc" > ~/customrc
$ echo "echo bashrc" > ~/.bashrc
$ bash
systemrc
bashrc
$ bash --rcfile ~/customrc --norc
$
Current behavior:
$ bash --rcfile ~/customrc
systemrc
customrc
$
Expected behavior:
$ bash --rcfile ~/customrc
customrc
$
Fix:
To fix the behavior so it matches the documentation, SYS_BASHRC should
only
be executed if --rcfile is NOT used.
Also, documentation should be updated to clarify that --norc option
disables
--rcfile option.
Last but not least, -DSYS_BASHRC compile option should be properly
documented,
or at least included in configure options (as in
--enable-system-bashrc)
The attached files are:
0000-xxx.patch: enables SYS_BASHRC so bug can be reproduced and the fix
can be tested
0001-xxx.patch: Fixes the bug. This is the ONLY patch meant for merge.
They were succesfully tested on git "master" branch (4.2 patchlevel 20)
