Dear monks

I am running a perl script Depends upon the shell I have to add some feature to my script.

If my login shell is csh from the command line I can change to korn shell by giving 'ksh'. same way I can change to any shell I want ( 'bash','csh','sh').

From the command line if I execute echo $0, I will be able to find the shell name. How can I find this inside a script whithout using `echo $0`. I think there is no use of this command inside a perl script.

My code would be similar like this

$shell_name = find_the_shell if ( $shell_name eq 'bash' ) { # Blah .. Blahhh } elsif ( $shell_name eq 'ksh' ) { # Blah .. Blahhh } elsif ( $shell_name eq 'csh' ) { # Blah .. Blahhh }
