how to find which shells i have in my linux determining the available shells which

we can ask your current shell to locate the various shell programs available on your system in the diretories listed in your path.

enter:

which sh

if the path to the executable displayed is for sh, the sh Bourne shell is available on your sytem. enter either of these commands:

which cs
which tcsh
which bash
which ksh

if you dot not have a ksh on your sytem and you are runing linux, you can install it. on most linux distributions, the korn shell is called pdksh for public domain ksh in the rpm packages. the most current instructions fo adding pdksh are availabe at the www.muster.com web site.

i have reb hat on my system so this is what i see with the which sh command

/bin/sh
