Looking for a way to rename lots of files at once
for file in *; do
    new=${file//-/ - };
    new=${new//+/ };
    if [ "$file" != "$new" ]; then
        mv "$file" "$new";
    fi;
done

for a in * ; do
    mv $a $(echo $a | sed -s 's/-/ - /' -e 's/+/ /')
done

for f in `ls` ; do
    mv $f $(echo $f | sed -s 's/-/ - /' | tr '+' ' ')
done

for f in `ls` ; do
    n=$(echo $f | tr -s 's/-/ - /' | tr '+' ' ')
    if [ $f != $n ]; then
        mv $f $n
    fi
done

for FILE in `find . -maxdepth 1 -type f`; do mv "$FILE" "`echo "$FILE" | sed -e 's/-/ - /g' -e 's/+/ /g'`"; done;

printf "%sn" * |
sed 'h;y/+/ /;s/-/ - /g;x;G;/(.*)n(1)/d;s/(.*)n(.*)/mv -v '''1''' '''2'''/' |
sh

for file in *
do
  newFile=${file//+/ }
  newFile=${newFile//-/ - }
  mv "$file" "$newFile"
done
