Linux Ebooks

Hi folks, in my inbox I have a new email from tips-linux.net team, sincerely it's kind of weird 'cause the whole email body says "You might find useful these books", so the list shown below is being displayed:

• Pro bash programming.
• Expert shell scripting.
• Beginning linux command line.
• Bash pocket reference.
• Linux command-line and shell-scripting bible.

Finally a big acknowledge to our friends from tips-linux.net, today there's no original source 'cause as I said, I've received it into my inbox.

I hope somebody could find this helpful.
