RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
