Greetings fellow newbies,
I was trying to learn more about ~/.bashrc, ~/.bash_profile, and /etc/bashrc this morning when I ran across a link to "Beyond Linux From Scratch." It covers much more than the bash shell, and I have a feeling I'm going to learn a lot from it.
If anyone else is interested, head on over to http://www.linuxfromscratch.org/blfs/
, choose the mirror closest to you, then from the left navigation menu, choose to either download it or read it online.
