sticky
STICKY(7) BSD Miscellaneous Information Manual STICKY(7)
NAME
sticky -- Description of the `sticky' (S_ISVTX) bit functionality
DESCRIPTION
A special file mode, called the sticky bit (mode S_ISVTX), is used to indicate special treatment for directories. See chmod(2) or the file
/usr/include/sys/stat.h
Sticky files
For regular files, the use of mode S_ISVTX is reserved and can be set only by the super-user. NetBSD does not currently treat regular files
that have the sticky bit set specially, but this behavior might change in the future.
Sticky directories
A directory whose ``sticky bit'' is set becomes a directory in which the deletion of files is restricted. A file in a sticky directory may
only be removed or renamed by a user if the user has write permission for the directory and the user is the owner of the file, the owner of
the directory, or the super-user. This feature is usefully applied to directories such as /tmp which must be publicly writable but should
deny users the license to arbitrarily delete or rename each others' files.
Any user may create a sticky directory. See chmod(1) for details about modifying file modes.
HISTORY
The sticky bit first appeared in V7, and this manual page appeared in section 8. Its initial use was to mark sharable executables that were
frequently used so that they would stay in swap after the process exited. Sharable executables were compiled in a special way so their text
and read-only data could be shared amongst processes. vi(1) and sh(1) were such executables. This is where the term ``sticky'' comes from -
the program would stick around in swap, and it would not have to be fetched again from the file system. Of course as long as there was a
copy in the swap area, the file was marked busy so it could not be overwritten. On V7 this meant that the file could not be removed either,
because busy executables could not be removed, but this restriction was lifted in BSD releases.
To replace such executables was a cumbersome process. One had first to remove the sticky bit, then execute the binary so that the copy from
swap was flushed, overwrite the executable, and finally reset the sticky bit.
Later, on SunOS 4, the sticky bit got an additional meaning for files that had the bit set and were not executable: read and write operations
from and to those files would go directly to the disk and bypass the buffer cache. This was typically used on swap files for NFS clients on
an NFS server, so that swap I/O generated by the clients on the servers would not evict useful data from the server's buffer cache.
BUGS
Neither open(2) nor mkdir(2) will create a file with the sticky bit set.
