Name
       sticky - executable files with persistent text

Description
       The  sticky  bit	 (file	mode  bit  01000), is used to indicate special
       treatment for certain executable files and directories.

       While the sticky bit, mode 01000 is set on a sharable executable	 file,
       the  text  of  that file will not be removed from the system swap area.
       Thus the file does not have to be fetched from  the  file  system  upon
       each execution.	As long as a copy remains in the swap area, the origi‐
       nal text cannot be overwritten in the file system, nor can the file  be
       deleted.	 Directory entries can be removed so long as one link remains.

       Sharable files are made by the -n and -z options of

       To  replace a sticky file that has been used, clear the sticky bit with
       and execute the old program to flush the swapped	 copy.	 This  can  be
       done  safely  even  if others are using it.  Overwrite the sticky file.
       If the file is being executed by any  process,  writing	will  be  pre‐
       vented.	 It  suffices  to  simply remove the file and then rewrite it,
       being careful to reset the owner and mode with and Set the  sticky  bit
       again.

       A  directory  whose sticky bit is set becomes an append-only directory,
       or, more accurately, 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 superuser.  This feature is usefully applied to directories such as
       which  must  be	publicly writable but should deny users the license to
       arbitrarily delete or rename each others' files.

Restrictions
       Only the superuser can set the sticky bit.

       Is largely unnecessary on the VAX.  It matters only for large  programs
       that  will  page heavily to start, since text pages are normally cached
       incore as long as possible after all instances of a text image exit.
