The `/^$+` part makes no sense. If you you just want to test for the presence of digits then a simple `/[0-9]/` will work splendidly.	[reply] [d/l] [select]

Continuing hippo's advice, you should continue to the grep part next. Cheers, Sören (hooked on the Perl Programming language)	[reply]

but since /0-9/ can be anywhere in the word , not necessarily in beginning or end	[reply]

Precisely. eg. `$ perl -e 'print "Matched.\n" if "foo8baz" =~ /[0-9]/;' Matched. $ perl -e 'print "Matched.\n" if "foobaz" =~ /[0-9]/;'` [download]	[reply] [d/l]

" ... what i tried doing is that some $ before num and some $ after it " Do you, by any chance, mean you tried to deal with data that included a "$" sign... such as: `abc12$` or `$98abc` or `$$zyx5abc` or something similar? If so, you'll have to escape the "$" sign (with a preceding backslash, "\") in your regex. `perl -E "my $s='$abc123'; if ($s =~ /\$/ ) { say 'Found a dollar-sign';}` which outputs: `Found a dollar-sign` Otherwise, (slightly oversimplified), the regex engine uses the "$" sign is only to mark an EOL. Updated by quoting a possibly mis-understood part of OP's latest question. If you didn't program your executable by toggling in binary, it wasn't really programming!	[reply] [d/l] [select]
