default bash PS1

[neylitalo]

I need to know the default bash PS1 variable, usually set in /etc/bashrc or /etc/bash/bashrc, could someone post the relevant lines here? If you don't feel like digging, the entire file will do just as well.

 

If you don't have GNU/Linux or some other Unix derivative, then you don't have what I need, but thanks anyway.

Hm... it seems that Gentoo is the odd man out when it comes to setting PS1 in the bashrc file. Ah, well. Thanks for the rc's, Steve.
