It's just a warning (the code works) that you're using $fh1 untested. This
doesn't complain

That's a good one, too - note, you do want to use an absolute path in there
(and elsewhere) if you're writing this in a script. Something folks often
misunderstand is that the script is run re

But if you have to use a regex, I suggest using the /x modifier to make it
easier to read an maintain the regex:
#!/usr/bin/perl
use strict;
use warnings;
for my $s (qw/binutils-2.23.52.0.1-12.el7.x86_64
compat-libcap1-1.10-3.el7.x86_64 compat-libstdc++-33-3.2.3-71.el7.i686/) {
my ($name, $vers
I would suggest you change your approach and user the query mode of RPM to get
your information instead of build up a regexp:
rpm -qa --queryformat "%{NAME}\n"

Subject: regex to get the rpm name
I don't think a regex is the simplest and most maintainable way to get this
information. I think it is probably better to take advantage of the
structure of the string to discard and find information:
#!/usr/bin/perl
use strict;
use warnings;
for my $s (qw/binutils-2.23.52.0.1-12.el7.x86_64

Hi All ,
I want to get a regex to actually get the rpm name and version for
comparison :
binutils-2.23.52.0.1-12.el7.x86_64",
compat-libcap1-1.10-3.el7.x86_64"
compat-libstdc++-33-3.2.3-71.el7.i686
(^[a-zA-Z0-9\-]*)\-\d'
First part of the regular expression is ^[a-zA-Z0-9\-]
which me
