ksh vs bash
Hi,

I've a general question regarding shell. I 've seen that every where i worked in production environment people are using ksh .. but i like to use .. bash .. is there any particular reason why hardcore sysadmins use ksh ?

My answer: because ksh is (1) installed by default on more systems, and (2) is generally available no matter what boot mode (ie, single-user), and (3) older admins don't know/care about 3rd party (ie, GNU) tools. Also, (4) because of (1), you can write shell scripts that are more "portable".

In terms of capabilities, I doubt there are many differences between bash and ksh. But there are subtle differences that can and will break shell scripts.

ksh supports co-processes. It also compiles scripts and runs the compiled code and this makes it very fast. But if you like bash go ahead and use it... it's not a terrible shell.
