If I use setgid (chmod g+s) on a file (not a directory), it turns a dark yellow in the file list (of the particular Linux variant I'm using, anyway). But as far as I know, setgid doesn't actually do anything when applied to non-executable files.
Does it?
And, does anyone have a find command to find all non-directories and remove their setgid bit?
Best Answer
As you suggest, setgid only applies to executable files and directories.
You can
Just don't do this in /usr/bin!
