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.
+++ This bug was initially created as a clone of Bug #671003 +++
Description of problem:
Here's the content of the csh profile /etc/profile.d/cvs.csh:
# change default from rsh to ssh for cvs command
setenv CVS_RSH "${CVS_RSH-ssh}"
This is not valid tcsh syntax. This kind of variable substitution
is only valid in POSIX shells.
Right now, this bug does not result in an error when starting tcsh, but
only because current tcsh versions ignore that line for the simple reason
that it's missing a newline. However, the upcoming tcsh 6.18.00 will NOT
ignore that last line anymore and a syntax error will occur.
The correct syntax for csh and tcsh is
if ( "$?CVS_RSH" == 0 ) setenv CVS_RSH
I hope this can be fixed soon. And, please add a newline since otherwise
the line will never be executed with the current tcsh 6.17.00.
Thanks,
Corinna

Oops, I missed to set CVS_RSH to ssh. So, here the *corrected*
correct syntax for csh and tcsh:
if ( "$?CVS_RSH" == 0 ) setenv CVS_RSH ssh

cvs-1.11.23-11.el6_0.1.x86_64 in RHEL-6.1 is affected too. The CVS_RSH variable is not set on log-in into csh because missing new line causes silent ignorance of the command.
As we are adding CSH support into RHEL-5 (bug #571559), we should make sure RHEL-6 provides the same experience.
