Iam new to shell scripts.
Can anybody tell what are all the shell types(bash,Ksh,Csh...) does the
following OS supports?

Unix-?
Linux-?
Solaris-?

And also when to use which shells?
Advantage/Disadvantage of shells compared to other shell types?

Thanks and Regards,
Vasanth.

Pretty much any shell can be used on any os.

Most shell scripts are written using Bourne shell (sh/bash/ksh/etc.)
syntax, but this is by no means universally true. Your choice of
interactive shell will be largely dictated by personal preference.

For interactive use, many people like to use Bourne-shell variants like
bash, ksh, etc., because these are frequently used for writing batch
scripts. This means the syntax for your interactive use is the same
syntax you use for writing scripts.

On the other hand, many people (poor, misguided souls :) ) prefer to use
csh variants.

Shells such as bash, zsh, or tcsh have real advantages for interactive
use (such as better history handling, flexible key bindings, flexible
command line completion) over their ancestors (sh/csh/etc.).

All current OSs (Unix-type) will have a POSIX shell. It is a
superset (more or less) of the Bourne shell.

That shell may be bash, ksh or ash (or something else), but if you
stick to POSIX syntax, your scripts will run on all those systems.

Of the more than 100 scripts in my book, all except 6 are
POSIX-compliant. The rest require bash.
