probably make another post explaining what a sticky bit is and how it’s used, but for now i’m giving you just the code (great for web server directories). find /var/www -type d -print0 | xargs -0 chmod g+s

find . -maxdepth 99 -mindepth 1 -type d -printf %p\\n ls -1l | grep ‘^d’ | awk ‘{print $8}’ find ./ -type d find . -maxdepth 99 -mindepth 1 -type d -print0 -printf %p\\n | xargs -0 ls -d ls -hl | grep ‘^d’
