This is totally wrong, thats not what the switches mean. -e is for
expression (do'h) and -n loops over the input (I think, not sure still) and
-l is hard for me to understand let alone explain so here is the text:


enables automatic line-ending processing. It has two separate effects.
First, it automatically chomps $/ (the input record separator) when used
with *-n* or *-p*. Second, it assigns $\ (the output record separator) to
have the value of *octnum* so that any print statements will have that
separator added back on. If *octnum* is omitted, sets $\ to the current
value of $/
 . For instance, to trim lines to 80 columns:

I will try something out if it works will send you the regex.
