C Shell
The C shell executes the file /etc/csh.login when you log on to HP-UX. It then looks for the file .login in your home directory. If it exists, it is executed. Next, the C shell executes the file .cshrc in your home directory (also executed any time you invoke a new copy of /bin/csh). If you use SAM to add new users, the files /etc/d.login and /etc/d.cshrc are automatically copied to the home group of the new user. If you want to make global changes to the commands executed at login time, you should change these files:
/etc/csh.login {always executed at login}
/etc/d.login {default .login for new users}
/etc/d.cshrc {default .cshrc for new users}
