How can I know how many shells my system support(..is there any specific command ) ???

Almost all distros can support any number of shells. To see what shells you do have installed check your /etc/shells file.

Normal shells installed are
tcsh
csh
bash
dash (Ubuntu based distros)
sh (bourne shell) normall a sym link to bash
ksh

That command does not work on all distributions. That is why it is better to look through your shells file as that is standard on almost all version of Linux, and even on AIX, and hp-ux

I completely agree with you jstephens84.

But I replied by looking at the distros ubuntu and backtrack in the profile.

That is interesting. Have you tried it in Ubuntu. I just tried it on my mint laptop and the command does not work. I wonder if mint took out that option or if all debian based distros took that out?

I dont't have Ubuntu machine available right now with me. But I quickly went through man page of chsh in ubuntu, interestingly Ubuntu doesn't provied -l option with chsh.

http://manpages.ubuntu.com/manpages/...n1/chsh.1.html

But chsh -l works very well under Redhat based distros..
