Re^3: Regex String

You're welcome! And in that case, I'd change those checks to the following:

die "Not a valid file, Check output!" if $dumpbuf =~ m/[^0-9A-F]/; #ma
+tch one
die "File contains only zeros, Check output!" if $dumpbuf !~ m/[1-9A-F
+]/; #match two

(In particular, note that the second regex should include A-F, since otherwise some valid files will be rejected.)

You could also try the following, as an alternative solution: `die "Invalid file, check output!" unless $dumpbuf =~ /^(?!0*$)[0-9A-F]+$/; # Ensure file contains a hex string other than all 0`	[reply] [d/l]
