You can make lots of things in linux - people commonly use it for web/file/email server. Where I work we use it for a pbx as well. There are all sorts of interpreters and compilers available for linux so you can write your own program to do whatever you want.
As for perl, its a scripting language that can run on linux - I don't know how many details you want to know about perl but there is a lot of documentation for it if you google for it.
Please give me a specific example on what exactly I can make as a beginner...
I have just learned how to use some of the basic commands at the command prompt in Linux such as grep, ls, rm, ps, etc.......
I have also heard of shell scripts....On what subject can I make a Linux shell script which is not too basic and not too advanced for me....
This minor project of mine is for 100 marks and I have to make my project accordingly.......
Plzz reply..........
Thanks...
