Customizing /etc/csh.login
The /etc/csh.login file is used for setting environment variables such as TERM and is only read by tcsh when it is a login shell.
Important: Because /etc/csh.login is
the tcsh equivalent to /etc/profile for sh,
you need to keep system-wide information for both sets of users in
synch. Any customization that you have done for /etc/profile (such
as setting environment variables) must be duplicated in tcsh syntax
in /etc/csh.login. Future changes to /etc/profile also
need to be made to /etc/csh.login. If you maintain
a non-z/OS UNIX system, you
could consider porting /etc/csh.cshrc and /etc/csh.login from
that system to z/OS and
merging them with the z/OS samples.
