hiii friend

i am confused which shell scripting i chose to learn!!!!!!!
different type of shell are available like bash,perl,python, ,csh,tcsh,kron etc.

i wanted to learn shell script that is mostly used by network administrator to configuer network.because i am a beginner of linux network admin..

pls give me a proper suggestion to choose about Shell Script.

thanks in advance

Most Shell scripting is done in a Bash shell these days.
Perl and Python (and Ruby and ..) are scripting languages but not shell scripting. Shell scripting refers to writing a script with the tools / language available in the shell itself. Python and Perl are external languages that exist independent from the shell.

A Linux admin can and will use any and all scripts that fit the job. Bash, Python, Perl and Ruby are obvious starting points to learn scripting.

Technically, Perl and Python are not shell scripts.

I wouldn't waste time for csh, tcsh and I have no idea what “kron” is. Did you mean ksh? In that case I wouldn't waste time for it either.

It seems that many people no longer look at Perl favourably, so some folks may look at you weird if you tell them you are learning Perl. I personally have put Perl and Python in pretty much the same category.

But with what we're left, Perl, Python and Bash, the last one is something completely different then the first two. Bash is shell after all, and to be honest, you should know both shell scripting and Perl/Python, so I'd recommend learning (Bash and Perl) or (Bash and Python).

Having said that, I would actually recommend to keep it pure POSIX shell. You can find description of POSIX shell at http://pubs.opengroup.org/onlinepubs...idx/shell.html (the site uses frames and http://pubs.opengroup.org/onlinepubs/000095399/ gets you to the main page). For Bash there's Advanced Bash-Scripting Guide).

For Python see http://python.org/doc/ and finally for Perl there's a list of some books. Learning Perl is a good read.

some pepple tell me perl is the best choice..because perl is easy and as similar as c++ language.because i hav no more time to learn both bash and perl...
what would u say about perl..

Perl is good, there is a large community and a lot of free online information.
Perl is however not similar to C++. And I mean really, really not similar.

So, to learn scripting / programming Perl is a good a choice.

If you want to be a Linux Network Admin Shell scripting is mandatory imho. It is the quick and dirty way to make things happen when you're in a hurry.

So if that is your goal: take the time to learn both - it will help a great deal to land a job.

Generally, when you write a script, and start it with #!/bin/sh you cannot tell what shell will actually interpret it: ksh, bash, dash or other. So test it with dash: it is a minimalist shell with minimal flexibility and no extensions.

Absolutely you have to learn bash/ksh scripting.
After, if you want/can, perl too.

Spell out your words, please. And you don't have to learn anything in any particular order...learn bash first, or perl, or any other language...just pick one. Go to Google, and look up any of the many thousands of easily-found tutorials/documents, and read them. Do some exercises, write scripts, and figure things out. That's how you learn. There is a link to bash scripting tutorials in my posting signature, and many more you can find with a quick Google search.
No...we are not going to email you tutorials. This is a community forum, not the place to come for personalized, one-on-one email support/training.
