Re: Replacing multiple spaces into one character?

Er, it works for me. To wit:

$str= "   perlmonks   is   the   coolest";
$str =~ s/\s+/_/g;
print $str;
[download]

prints: _perlmonks_is_the_coolest

(I left out the i modifier because space is the same in capital or lower-case. I don't think that would change the behavior, though!)

Agreed, it works exactly as r.joseph presented it. However you may want to think about using `$str =~ s/ +/_/g;` [download] instead, since it doesn't mess with your newline characters. That is, with your version "perl\n" becomes "perl_". - Boldra	[reply] [d/l]
