.bashrc_afs

# Great Practical Ideas for Computer Scientists
# Sample .bashrc file

# We provide a few (useful) aliases and scripts for you to get started:

### afsperms <arguments to fs sa> -- Recursively runs fs sa on a directory
### cc <arguments to gcc> -- Invokes gcc with the flags you will usually use
### valgrind-leak <arguments to valgrind> -- Invokes valgrind in the mode to show all leaks
### hidden <arguments to ls> -- Displays ONLY the hidden files
### killz <program name> -- Kills all programs with the given program name
### shell -- Displays the name of the shell being used
### get_cs_afs_access -- Sets up cross-realm authentication with CS.CMU.EDU so you can access files stored there.

# More features may be added later as thought of or requested.
