The "Sticky" Flag
Originally written by
- The "sticky" flag, is mostly meaningful when set for a File containing
an executable program, or for a Directory.
- When set for a File, it means that the File should be copied into
the swap device, rather than loaded from its original location. This
could make the File load faster.
- When set for a Directory, it means that users cannot rename or delete
Files in this Directory, unless they own these Files.
- This flag is normally set for Directory all users can create Files in,
such as "/tmp" or "/var/spool/mail".
