Not to mention .cshrc (csh) or .tcshrc (tcsh) in a networking environment,
where .login (csh && tcsh) is not sourced when logging in remote. And 
/etc/cshrc the csh equivalent to the systemwide /etc/profile in the Bourne
Shell, supported by some csh's.

V7, System III, and BSD derived systems have a minimal PATH set by the
login program, while System V derived systems have no builtin PATH from
login, they get the PATH from the places mentioned by Doug above and the
ones given by me.
