Is there a method to pass a shell assigned variable to perl?
For ex:
ABC=xyc
perl -ne 'print $ABC'
In awk you could use ENVIRON["varname"], is there something compatible in perl.
You can do the same in perl with the special hash named %ENV. for instance: print $ENV{'SHELL'}
or you can use the env module: perldoc -f env
perl is case sensitive so that should be Env not env.
