Hi Johnno--
You can use '+' in a regex to mean 'one-or-more', so
s/\|+/|/ would mean "replace one or more pipe with
a single pipe" (you don't need to escape the pipe
in the replacement string).
As a style matter, you can enclose the pipe in a
chacter class with []s to make it easier to read:
Hi John,
You forgot at least a backslash,
$string =~ s/\|+/\|/g;
Should do the job.
