As a normal login shell, bash 'sources' system-wide file /etc/profile, whrer the system environment and path can be set for bash users. However, it is not run when the system interprets the shell as non-interactive. The most important case would be single user mode, where csh is executed on the machine. The /etc/profile is not run and the path is inherited from the csh daemon. bash receives command line arguments -login and -i that can be used to set as a login shell or interactive shell respectively. The user can overwrite values set in /etc/profile by creating a file ~/.bash_profile, ~/bash_login or ~/.profile. Note that just the first one of these is executed thus differing of the logic of csh initialization. ~/bash_login is not executed specially for login shells and if .bash_profile exists, it is not executed at all! If bash is used with name sh instead of the name bash, it emulates original Bourne shell initialization: it sources just files /etc/profile and ~/.profile and just for login shells. As a login shell tcsh executes the following files in this order: /etc/csh.cshrc /etc/csh.login ~/.tschrc ~/.cshrc (if .tschrc is not found) ~/.history ~/.login ~/.cshdirs tsch can be compiled to execute login scripts before cshrc scripts. Beware! Non-interactive shells execute just the "cshrc scripts" login scripts can be used to set the path just once in the login. Hope this helps.
