.bashrc

Revision as of 20:38, 5 August 2012

.bashrc is a script located in a user's home directory which will be executed when the bash shell starts. an example .bashrc is below. note that this is a bashrc from a linux system which I commented out a bunch of stuff that isn't supported over ssh/terminal sessions.
