I dug up the two Perl scripts I got quite a while ago from somewhere -
probably this list. If they don't do exactly what you want, they're
easy to modify.
#!/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).
#!/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//\032/ if (eof); # DOS ^Z at end of file.
