Rename file script.

This might come in handy for some of you Unix/Linux people out there. It adds a string to the name of a file before the file extension. Great for renaming tons of files in a similar manner. There is probably a better way to do it but this works well for me.

echo "Enter Name Addition: "
read newadd

for file in *
do
filename=`echo $file | awk 'BEGIN {RS="."} {print $0}'`
filename2=`echo $filename | awk '{print $1}'`
newname=`echo $file | sed -e 's/'"$filename2"'/'"$filename2-$newadd"'/g'`
mv $file $newname
done
