To convert a file from DOS format to unix format, you can use the following script. Note that on recent unix systems this script comes built-in....
#! /bin/sh
if [ ! "$1" ] ; then
echo `basename $0` file ...
echo ' convert' filenames from dos to unix
exit 1
fi
while [ "$1" ] ; do
TMP=$1.$$
if tr -d '\r' <"$1" >"$TMP" ; then
cp -f "$TMP" "$1"
fi
rm -f "$TMP"
shift
done
