Even easier. Same as above, but the regex simplifies to: `s/<([0-9A-F]+)>/hex($1)/eg;` [download]	[reply] [d/l]

Ah, you're using an ancient perl. Simply leave out the `use feature qw/say/;` line, and replace `say;` in the loop body with a `print` statement: `while(<DATA>) { chomp; s/<([0-9A-F]+)>/hex($1)/eg; print "$_\n"; }` [download] Actually, you could probably also get away with not `chomp`ing your input in the first place here: `while(<DATA>) { s/<([0-9A-F]+)>/hex($1)/eg; print; }` [download] And at this point, assuming you merely want to output the results and do nothing further with them in this particular script, the whole script can be turned into a oneliner you can directly enter on the command line. Using perl's `-p` switch (see perlrun): `$ perl -pe 's/<([0-9A-F]+)>/hex($1)/eg' /home/stummala/a JDW-HP 1MVWV93V7j2Hxsa0Ag6 24:00:00 SUBJECT_EXACT _Did you160serve our +160country? -New VA Home.Loan Program_ JDW-HP 1MVWV98Ddd4fLsa0Ag6 24:00:00 SUBJECT_EXACT Did.you.serve_our co +untry?
