in reply to -w more than a warning?

Your file has a bunch of binary carriage returns in it. Looks like you did not correctly transfer the file from a non-Unix OS to Unix (or vice-versa) in ASCII form. The problem occurs because *with* the -w flag, the carriage return can be safely ignored by Perl, however, without it, your line looks something like this: 
#!/usr/bin/perl^M

Since the carriage return has to be treated as if it were a normal ASCII byte, it's looking for the binary perl^M to execute your script, not perl. Thus, you get "not found".

The fix: Transfer the file again correctly, dropping the carriage returns. Alternatively, you can use the search/replace feature in, say, vi, to strip them out: :%s/^V^M//g (where the ^V is a control-V (quote the next character) and the ^M is a control-M), or use something similar in a Perl one-liner.

    You can also do the following, which is a little easier, IMHO. 
    vi nastyDOSfile.pl
:set ff=unix
:wq

    'ff' is a synonym for 'fileformat'. I imagine there's some useful little command line utility that could process all the files in a directory, but I'm not THAT much of a Unix hack.

      You mean Perl? (: 

      perl -pi.dos -e 's/\r//'

      Doing this under DOS is harder since you have to get the calls to binmode thrown in at the right places. I think you can check the FAQ for more info.

        Or, my favorite, just because it looks kind of magical:

        perl -015 -pi.dos -e 'chomp' filename

    yes, that does appear to be it....

    this script was written by a co-worker who does his editing on win32...I've never seen this before...very interesting. Anyway, i've had him set his editor up to output in UNIX format so all should be well.
