How can you recognize a shell (C / Korn / Bourne) just by looking at the prompt?

C shell - @
Bourne - %
Ksh - $

Hi gopi
Thanks for your response
I know the answer which u have mentioned here but we can also change the command prompt using the chsh command ,at this point, again this becomes a question?

Hi



If we type any not existed command then the shell tell you that the command is not existed along with the shell name

Ex:
$ hello
then it says
bash:command not found
means that you are working with bash shell

echo $SHELL will give you the shell name as well as the path.

I dont think so just by looking at the prompt one can recognize the shell [inputs pls, if otherwise], however you can run small commands to get the shell that you are using
    ps -p $$

should be your answer.

There is no such way just by looking at the prompt as this is changable.
