How do I find all files that are *not* group writeable?
Assuming that the linked question would run on your system, you can invert the match with !
:
find ! -perm -g=w
Also, you can read the documentation for find
by looking into the manpages:
man find
On BSD derived Unix system (macOS, FreeBSD, ...) you need to add a path to find
. So for a more compatible version add .
to search in the current directory and !
to invert the match:
find . ! -perm -g=w
