Just some further info...
if you were to do a hex dump ("hd") of the text file, you would see at the
end of each line an "0d 0a", that's an ASCII 13 followed by an ASCII 10,
aka CRLF.
BTW, two simple perl scripts which were posted on this list a long time ago
(sometime before Oct. 5, 1997) take care of CRLF conversions for you:
---unix2dos---
#!/usr/bin/perl -pi
#
# Convert Unix text file to DOS file format. Conversion is done in-place.
#
# Usage: unix2dos unixfile ...
print STDERR "Converting \"$ARGV\" ...\n" if (eof || ($. == 0));
s/$/\015/; # tack on ^M
s/\n/\n\032/ if (eof); # DOS ^Z at end of file.
---dos2unix---
#!/usr/bin/perl -pi
#
# Convert DOS text file to Unix file format. Conversion is done in-place.
#
# Usage: dos2unix dosfile ...
print STDERR "Converting \"$ARGV\" ...\n" if (eof || ($. == 0));
s/\015$//; # strip ^M from end of line.
s/\032$//; # strip ^Z if we see it (which'll be at EOF).
