trial and error and creating useful projects for yourself is the best way to learn scripting.

find tasks that you tediously do everyday and try scripting them for your own use.

I have found the O'Reilly book "Unix in a Nutshell" by Daniel Gilly (ISBN 1-56592-001-5) extremely helpful when the man page confuses the hell out of me about a command.

I think since you are essentially starting from scratch that I would immediately suggest a Plan P. Rather than trying to learn shell scripting (you will absolutely, positively need some), if I were starting over, I would learn Perl. If you do there is very little reason to learn awk, grep, cut, paste, ... --- all the stuff that makes it possible to do useful things in the shell.
Don't misunderstand, it's very important that you are at least somewhat proficient in the shell but that's going to occur as a by-product of learning Perl. You will also learn regular expressions so there is really no downside to this and as an added benefit, if you learn Perl, you also have an extremely powerful scripting language for Windows as well.

In any event, O'reilly has some nice books on Perl and the Shell.

From the HP technical documentation web site, http://docs.hp.com/

you can find the HP shells user's guide, with a chapter or two on scripting, http://docs.hp.com/hpux/pdf/B2355-90046.pdf

HP education has a good course on shell scripting. I've seen the material, but never took the course.

If you have the budget, its a good idea.

Having only been into *nix for about 4 years now, I'll pass on the a great piece of advice I was once given. "Buy an old UNIX book". Sounds a bit bassackwards, but the older books contain more nifty features and forgotten shell tricks than most any new book on the shelves these days. My personal favorite is "A Practical Guide to UNIX System V 2nd. Ed" published 1991. If you have a PC Recycler in the area, they get these things in all the time. I once even scored an entire box full of circa 1992 official HP books for $1.

I second Mr. Stephenson. Learn Perl, granted there are things that perl is overkill for. But I find myself mostly programming perl whenever I need a script for something.

Plus they are things that you just can't accomplish easily with a shell language. So you will be looking for another solution.

I've been thinking about your concern...

If you want to learn scripting from the shell language, then search itrc.hp.com for sample-scripts. try them and make changes.

once you make a change you own the code, yes, learn from the best, and apply your own changes (sort of your own personal touch, if you like.)

you learn from other script programmers, then you become a better one yourself...

hope this gives you some focus in becoming a better script writer..

best of luck

I found the best book for scripting and all unix admin is "Unix Power Tools".

Hi SM,

the classical book "The Unix programming environment" (Kernighan and Pike) is a must read reference, there are 3 chapters very interesting about shell programing and filters.

Hello,

Whatever book you pick, look for one that comes with numerous and explaned exemples. Shell scripting is pretty readble right away, but script languages that uses regular expression or implicit behaviour can be tricky ! Practice is the best teacher of all ;)

Cheers

TLDP.ORG has a free guide called the Advanced Bash Scripting Guide. Granted, it's primarily for linux, but it can be really helpful in tight spots.

hi SM,

What you have to do is start using scripts which are already there. start with shell scripts they are very easy to use and learn also. Then after some time you can start writing simple scripts.

When you keep on writing scripts only you can become an expert. Belive me its not tough to become an expert if you start writing now.

Check this link these are sys admin scritps posted in ITRC. Some of them are complicated and tough just look at them

I am doing the same thing .

hello

thanks for the replies

I will look into Perl for sure!

Thanks.
