Import a path defined in bashrc to perl script

I've defined a path (say, $MYPAT) in .bashrc file and I would like to use it in perl scripts, so that inside the script I just can write open(IN, "<$MYPAT/dir1/... How can I import this variable to directly use it in my script?

I guess is the same problem posted here How to use aliases defined in .bashrc in shell script but applied to perl.

Thank you!

There are so many modules for every work to make it possible. I think this module in CPAN would be helpful for you, just go through a little documentation.

Assuming $MYPAT is an environment variable defined in your .bashrc, you can access it using the special %ENV hash in perl, which contains all the environment variables for your process. See %ENV in perlvar.

my $path = $ENV{MYPAT};

Also, as a stylistic note:

  1. You should use lexical filehandles instead of globals
  2. You should use the three-argument form of open.

So instead of

open(IN, "<$path/dir1/...")

make that

open my $fh, '<', "$path/dir1/..." or die "yadda yadda";
