QUESTION: How to find shell that I am currently running

ANSWER: to check and see, all you have to do is send this command on your terminal console in linux


SHELL COMMAND:
sh --version


OUTPUT:
GNU bash, version 3.2.33(1)-release (i386-redhat-linux-gnu)

as you can tell from my output, it shows i am using the bash shell when i sent the sh command. so showing you what version of shell you are using is easy with this simple linux command.
