Chmod files to recursively give group same permissions as user

Chmod files to recursively give group same permissions as user Is there a unix command to give the group the same permissions as the user currently has on a file-by-file basis recursively for a directory tree? I.e. if a file is user writeable it should become group writeable, otherwise it should not be group writeable and so on.

"I can't think of an easy way to do that with existing commands. Maybe a script like this would help :

#!/bin/bash

DIR=""$1""

find ""$DIR"" -ls | while read a b perm c d e f g h i file; do
uperm=${perm:1:3}
uperm=$(echo ""$uperm"" | tr -d '-')
chmod g=$uperm ""$file""
done

Also, keep in mind that some perms for users might not apply to groups, and vice versa."
