Re: perl reading ^M on text mounts


Have you tried setting the environment variable PERLIO? I'm not a heavy PERL user, but I tend to have

PERLIO=crlf

if I'm likely to see CRLFs.

Dave.

Considering the usual speed of answers in this group and the persistent
silence on this one may I ask again? Perl doesn't seem to deal well with CRLF
text files as demonstrated below. Is that a known problem, any fix coming or
am I missing something?


Thanks for any insight,
Michael

If I execute this perl script

  de010597> cat x.pl
  #!/usr/bin/perl
  use strict;

  open( HO, "<x.txt" );
  while (<HO>) { print "$_"; }

on a text mount with an input file that has CRLF line endings perl
should treat this as a text file and strip the CR.  Only if I use
binmode HO should I see the CR.  But it doesn't:

de010597> ./x.pl | cat -A
bla^M$
de010597> cat -A x.txt
bla^M$

What am I missing here?
