My mind is blocked, and need your help.
I need to use an external filter command to further process
my Perl expression calculation, all within an Perl expression. How can I do
Let me illustrate with an example,
I need to calculate 12+34, then pipe this expression result through an
external shell filter command, say 'rev'.
ultimately, I'm going to use the whole expression in the second part of
string replace 's/.../.../eg' operation.
