You're welcome...
try the following:
a) put
use strict;
use warnings;
at the beginning of the script
b) look at the warnings and then declare the vars with my, see
perldoc -f my
c)
read the documentation
perldoc -f grep
to see why grep is not appropriate in the if clause
d) check the documentation
perldoc -f perlre
and the others mentioned at the bottom to see why
/^Options/ won't ever match a string beginning with '*' and why your script
doesn't print anything
e) hint:
don't use if, only use a regex to extract the parts you like, and extract them
directly into an array by catching the parts you like
.... and post the new code then :-)
