What are rcfiles?
There are several files in your home directory that specify configuration settings for your login sessions. At login time, during a session, and at logout, those files set up your environment and specify actions to be taken. They are normally referred to as rcfiles, and are hidden (their names start with a '.' character).
You can modify your rcfiles and reconfigure your environment in any way you like, as long as you still comply with the Undergraduate Conditions of Use. You must, however, keep in mind that the Help Desk does not support modified rcfiles.
Support for rcfiles
We provide a default set of rcfiles, which the Help Desk does support. Occasionally, we modify and enhance those files, especially following some reconfigurations or upgrades.
If you modifed your rcfiles, it is your responsibility to obtain the most up-to-date rcfiles.
Where are the default rcfiles located?
The default rcfiles are located in:
You can copy any of those files to your home directory, changing their names appropriately. You can also use a script that is able to do all that, as well as make backups of your existing rcfiles, for you automatically. The command to execute the script is:
/usr/local/bin/copyrcfiles -u CSID /cshome/CSID
