since it looks like my job lately is having a lot of scripting and I am pretty novice to it
I was searching for some books to learn command and to build scripts (if - case - and so on)
I found 3 books
Beginning the Linux Command Line
Pro Bash Programming: Scripting the GNU/Linux Shell
Beginning Portable Shell Scripting: From Novice to Professional
which one do you recommend me? have you read them? are they any good? any other book or resource?
thanks a lot
