Exactly! `^G1195874` is certainly not a number. Perl is loosely typed but it doesn't mean it should be used in strange ways, like expecting alpha-numeric characters to be treated like numbers. You might like to re-consider the two (rather) 'strings' you're trying to compare!	[reply] [d/l]

I understand your point, but when I print it with [] around the variables, it prints without the leading ^G: `print "[$version_on_disk]\t version on disk\n"; print "[$version_dns]\t version dns\n";` [download] gives me: `[1195874] version on disk [1195874] version dns` [download] So how does that ^G get in front of my variable :?

The other thing to realize is that a control-G is probably not a printable character. After all, it's supposed to ring a bell (on a teletype) or make some kind of beep noise (on a terminal).	[reply]

Try piping your output through `od`.	[reply] [d/l]
