Выдержка из man chmod:
The letters `rwxXstugo' select the new permissions for the
affected users: read (r), write (w), execute (or access
for directories) (x), execute only if the file is a direc-
tory or already has execute permission for some user (X),
set user or group ID on execution (s), sticky bit (t), the
permissions that the user who owns the file currently has
for it (u), the permissions that other users in the file's
group have for it (g), and the permissions that other
users not in the file's group have for it (o). (Thus,
`chmod g-s file' removes the set-group-ID (sgid) bit,
`chmod ug+s file' sets both the suid and sgid bits, while
`chmod o+s file' does nothing.)
The `sticky bit' is not described by POSIX. The name
derives from the original meaning: keep program text on
swap device. These days, when set for a directory, it
means that only the owner of the file and the owner of
that directory may remove the file from that directory.
(This is commonly used on directories like /tmp that have
general write permission.)
