Complex .bashrc file for Linux or UNIX
Very good and very complex .bashrc file for a Linux or UNIX system. I used this one ages ago and it is great to use. I have tried this on FreeBSD and Open Solaris and it works on either.

The .bash_logout file. This is executed when you logout of a session. On a virtual terminal, this will clear the screen.
