hello,please is there anyone who has an easier formular(if there is)for learning shell scripting.Am new in linux enviroment.

At tldp, I would start with the Bash Guide for Beginners, then "ABS" later.

Easier than what?? We have no point of reference as to what you know already, and how you are trying to learn.

I'll tell you what I think is the ONLY formula: Open a terminal and start typing commands. If you don't know what command to use, type "man -k <keyword>" After playing around for a while, then sit down with a book (such as the one above)

I think "Linux Shells by Example" by Ellie Quigley was very well done. The book covers bash and tcsh, sed, grep and awk with clear, well presented examples.

More advanced is "Wicked Cool Shell Scripts" by Dave Taylor. Some of the examples sghown are things you just wouldn't think of doing in the shell, but that's what makes it interesting.

"Shell Scripting Recipes: A Problem-Solution Approach" by Chris F. A, Johnson is a wonderful compilation of shell scripting functions and recipes, from the basic to amazingly complex and powerful.

My reviews of these can be found at:

I also recommend http://rute.2038bug.com/index.html.gz.
As above, the only 'formula' is to read those links and TRY THEM OUT. There's no substitute for getting your hands dirty, believe me.

there is this also.
