Re^2: Argument isn't numeric in numeric ge

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]
