If you want to classify a set of files into several groups based on different criteria, you can use the comma operator to perform multiple independent tests on the files. Here is an example:
find / -type d \( -perm -o=w -fprint allwrite , \
-perm -o=x -fprint allexec \)
echo "Directories that can be written to by everyone:"
cat allwrite
echo ""
echo "Directories with search permissions for everyone:"
cat allexec
find has only to make one scan through the directory tree (which
is one of the most time consuming parts of its work).
