Re: Downloaded Perl Scripts

["Alan Mead" <admead insightbb com>]

Is the file format dos or unix?  An easy way using vi (you may be deluged
with alternatives) is to edit the file (e.g., 'vi scriptname.pl'), then type
':set fileformat=unix', then enter, then write the file (':wq' or 'ZZ' will
write and quit).  I have found that newline differences can confuse perl (or
maybe bash) and 'dos' style newlines are common.
