Configuring The User's Environment

Configuring The User's Environment

A user's environment is determined by certain shell startup files. For C shell users, these are the files /etc/cshrc and, in their home directories, .cshrc and .login. For Korn Shell users, these are the /etc/profile file and the .profile file in their home directories. For Bourne shell users, these are the files /etc/profile and, in their home directories, .profile.

Shell startup files configure a user's login environment and control aspects of sub-shells created during a login session.
