OSXFAQ Daily Unix Tricks
Week 66 - Bash Tricks (8 December 2003)
by
Adrian Mayo - Senior Editor for Mac OS X Unix
Tuesday - Bash Startup Files
Create a file called '.bash_profile' in the root of your home directory. This file is executed when bash is invoked as a login shell (when you start a new Terminal session with Terminal.app). In here place all settings that are passed to sub-shells - i.e. set environment variables like PS1 (see Monday's tip) and the search PATH.
Also add the line:
. .bashrc
This will execute the second startup file.
Create a second file called '.bashrc' in the root of your home directory. This file is executed when bash is invoked as a non-login shell (when you type 'bash' to start a sub-shell). If you have added the line '. .bashrc' to '.bash_profile', '.bashrc' will then be executed for all (login and non-login) interactive shells. Place all other setting in '.bashrc'.
