Hi,

I would like to know which one is best suited in which tasks. How does one compare with another. I have experince with bash scripting and c programming. I am system administrator by profession which would you recommend.

with regards,
ashwin

Throw us some specific examples to discuss.

All 3 of them can do almost the same thing.
PHP was traditionally used for the web, however there is no stopping you to use it as a system admin tool if you want. PHP has extensive OS functions and modules to help in system admin tasks as well.
Python and Perl are 2 commonly used general purpose languages people use, not just for system admin, but for general programming as well.
They both can do the same thing, so my only recommendation to you is, to try and learn both. In fact, try to learn all 3 of them. Not only for learning purpose, but in the future, your knowledge of all 3 of them may come in handy.
