Description Ameya Patil 2021-03-31 19:21:59 UTC

Description of problem:

Anyone using (t)csh as a login shell has the variable p set to "/usr/sbin".

This can lead to unexpected consequences, e.g. when typing "cd p" (where directory p does not exist in the current working directory), example:

[user@host ~]$ /bin/tcsh -l
host_user% echo $p
/usr/sbin
host_user% pwd
/tmp
host_user% cd p
host_user% pwd
/usr/sbin

There is a foreach in /etc/csh.login that adds sbin directories to the path using the variable p. There should be an "unset p" after the foreach to clear the variable.



Version-Release number of selected component (if applicable):
Tested with the latest RHEL 8.3 - setup-2.12.2-6.el8.noarch.
And also on RHEL 7 with - setup-2.8.71-11.el7.noarch

How reproducible:
Everytime

Steps to Reproduce:
1. Install tcsh
2. Set its as the user shell or login using "tcsh -l"
3. Check that the variable p is set as /usr/sbin "echo $p"

Actual results:

Tcsh set variable p to /usr/sbin

Expected results:

Tcsh should clear variable p 

Additional info:

This also applies to Red Hat Enterprise Linux 7 so cloning this bug.
