There are two files that concern (t)csh:

/etc/csh.cshrc
and
/etc/csh.login

This is where you set up global stuff.

In each directoy, there are files like

.login

and one more ...?

OBS: Syntax for setting PATH is somewhat different:

setenv PATH "${PATH}:/moreppaths:/even/more/paths"

Also, syntax for loops and tests are different from BASH:

if ( test here ) then
....

foreach i ( spec here )
...
end
endif

More OBS: Do NOT let that put you off!

PS {
Good to know that people still enquire about csh.
It really is a good and simple shell for scripting.
