Is the shell available in Linux same as UNIX. In other words someone let me know what are the shells available in Linux?

The shells available in linux are
ash shell
bash shell - which is the default Linux shell
kron shell
Z-shell called as zsh
But I think someone shells are available. I hope someone would put their knowledge on that.

The shells available in linux are:
bash - Bourne-again shell
csh - C shell
jsh - Job control shell
ksh - Korn shell
rc - Plan 9 shell
rsh - Remote shell
sh - Bourne shell
tcsh - Popular extension of the C shell
zsh - Popular extension of the Korn shell

Of these generally Linux use bash shell as the default shell.

Hope to learn some more information about Linux shells in this discussion.
