Create a file ~/.login and put your commands (in sh syntax,
not csh) there. This file will only be executed at interactive
logins. See "man csh", section FILES for details.

I'm sure the login shell has to be defined by the system,
usually by the /etc/passwd file, field "shell"; therefore
see "man 5 passwd".

I don't think so, but it should work fine when you move
the commands out of the shell configuration file (which
is also read by script shells AND interactive shells) to
the login startup file (which is only executed if the
shell is an interactive login shell).
