Re: [inlimbo] remove whitespace

lets look at what you have:
The quick brown
fox jumped over
the lazy
dog
with the hidden characters exposed it can be simulated like this:
The\squick\sbrown\n
fox\sjumped\sover\n
the\slazy\n
dog"
\s is a space
\n is a newline
what you want to do is replace the newlines with a space, which can be done like this:
$line =~ s/\n/\s/g;
The "g" option tells perl to replace all occurances of the pattern in the string.
if its a windows file you may need to use:
$line =~ s/\r\n/\s/g;
or to cover both Unix and Windows style newlines:
$line =~ s/\r?\n/\s/g;
