Unix/NT file conversion problems

	Here are 2 shell scripts that come with IRIX.  to_dos works fine on
both IRIX and AIX. I haven't tried to_unix yet.

	to_dos:

	#! /bin/sh -e
	# convert a UNIX ASCII file to a DOS ASCII file by appending ^M at
the
	# end of each line and ^Z at the end of the file
	TMPFILE=/tmp/to_dos$$
	if [ $# -gt 2 ]
	then
	        echo "usage: to_dos [<unix_file> [<dos_file>]]"
	        exit 1
	fi
	if [ $# -gt 0 ]
	then
	        nawk '{printf("%s\r\n", $0);}' "$1" > $TMPFILE
	else
	        nawk '{printf("%s\r\n", $0);}' > $TMPFILE
	fi
	# Stick on the EOF character
	echo '^Z\c' >> $TMPFILE
	if [ $# -eq 2 ]
	then
	        mv -f $TMPFILE "$2"
	else
	        cat $TMPFILE
	        rm $TMPFILE
	fi

	to_unix:
	#! /bin/sh -e
	# convert a DOS ASCII file to a UNIX ASCII file by removing trailing
^M at the
	# end of each line and ^Z at the end of the file
	TMPFILE=/tmp/to_unix$$
	if [ $# -gt 2 ]
	then
	        echo "usage: to_unix [<dos_file> [<unix_file>]]"
	        exit 1
	fi
	# First strip out all carriage-return and ctrl-Z's
	if [ $# -gt 0 ]
	then
	        tr -d '\015\032' < "$1" > $TMPFILE
	else
	        tr -d '\015\032' > $TMPFILE
	fi
	if [ $# -eq 2 ]
	then
	        mv -f $TMPFILE "$2"
	else
	        cat $TMPFILE
	        rm $TMPFILE
	fi
