Hello sumitanshutiwari, and welcome to the Monastery!

One way is to store the shell script’s variable in the local environment, then access it from within Perl via the special %ENV hash. For example (in Windows):

13:29 >set FOO=bar

13:29 >perl -wE "say $ENV{FOO};"
bar

13:30 >

See perlvar#General-Variables.

Or, store the shell script variable(s) in a file, and access the file from within Perl in the normal way.

Hope that helps,
