Importing environment variables to Perl

Question

I\'m not sure if importing is the right word to use. I\'m a beginner in both Perl and Bash. I have set a variable on Bash, so when I do:

echo $PRDIR
         


        

Answer 1

If you want Bash to export a variable into the environment so it's accessible to programs, you can use the export builtin:

export PRDIR

Inside Perl, you would then access it using the %ENV hash:

my $varex = $ENV{"PRDIR"};
print "\$varex is: $varex\n";
