Try this one out..:) It works converting LF's to CR's and CR's to LF's...

--- Cut here and save as 'utoa' ---

# atou / utoa  (AppleToUnix & UnixToApple)
# December 15, 1990 - Evan Ron Aussenberg
#                     erast1@unix.cis.pitt.edu
#                     IN%"erast1@pittunix"
#
# Discription:
#   An Apple-to-Unix and Unix-to-Apple text file converter.  This is
#   a Unix shell script.  If you don't use Unix then you don't need
#   this (Well... maybe you do, but you can't use it).
#
# Disclaimer:
#   You're mileage may differ.  Also, this is just a little
#   nicer than making a t/csh alias... and it'll run from any shell
#   as long as you leave the ':' in the 1st line.  Okay?  Okay.
#
# To run this shell script you need :
#   1:  The unix command "basename"     | Just make sure these programs can
#   2:  The unix command "tr"           | be found in your $PATH environ.
#   3:  Save this program as "utoa"
#   4:  Type "chmod a+x utoa"
#   5:  Type "ln utoa atou"             | If you don't have the command
#                                       | "ln" or "link" then use "cp"
#
# Syntax:
#   atou [-v | V] file1 files2...
#   utoa [-v | V] file1 files2...
#
# Options (specifiy only one):
#   -v  Give terse output.  Normally no output is given.
#   -V  Give verbose output
