Proving which start-up file runs when

Answer

% grep echo ~/.cshrc ~/.login /home/ada/.cshrc:echo "cshrc ran" /home/ada/.login:echo "login ran" % csh cshrc ran % exit

The sub-shell reported `.cshrc` and stayed silent about `.login`. That is the whole rule: `.cshrc` for every shell, `.login` once at login. Aliases go in the first, `setenv` and `umask` in the second.
