On a Unix/Linux platform, you can remove all the CRs from a script
(or any file, really) with the following:

perl -pi.bak -e 's/\cM//g' script.pl

This removes all the CRs from the file named "script.pl", converting
all CRLFs to just LFs. (A copy of the original file will be saved as
"script.pl.bak".)

Also, how are you uploading the file to servers A and B? If you're
using ftp, I recommend using "ascii" mode before "send"ing or
"put"ting. This will convert your Windows line endings to Unix line
endings (so that you won't have to do it yourself later).

Another thing you might try is to call the script with "perl" in
the command line, like this:

perl script.pl

instead of just:

./script.pl

Not using "perl" in the command line will call whatever's specified in
the shebang line, and if the shebang line ends with a CR, like this:

#!/usr/bin/perl^M

the "perl^M" interpreter will be called, which can cause unexpected
things to happen.

(To confuse matters, some text editors will automatically hide the
"^M" characters, making you think they don't exist when in fact they
do.)

Calling your script with "perl" in front of it avoids several other
problems as well (like ones related to executable permissions and
$PATH issues), so I usually recommend that people run Perl scripts as
"perl script.pl" instead of just "script.pl".

So if you aren't already, call your script with "perl" before it
and see if that makes any difference.

I hope this helps, John.

Hi

Problem solved. The clue was 'ascii mode'. Server B uses vsftpd as the ftp
program.
Once I added ascii_enabled_download=YES and ascii_enabled_upload=YES all was
well.
Many thanks for pointing me in that direction.

.... or you could use dos2unix which is on most unix platforms. It
converts CRLFs to LFs.
