can any one suggest that how to use shell script with perl?

My first reaction as a Perl instructor is "don't." Unless you are pressed for time and the script is overly complex (bad idea in the first place) you should try translating the script's functionality to Perl.

What you've failed to communicate is what kind of script it is. Is it a Winbloze ".BAT" file? Is it a *nix shell script? (I've heard winbloze admins refer to BAT files as shell scripts.)

If you are talking about *nix shell scripts then most of the functionality you can obtain within a Bash, KSH, CSH or whatever script is available within Perl plus some that isn't.
