NAME    [Toc]    [Back]

       sync  -  Flush  file  system metadata and data from memory
       buffers to disk.

SYNOPSIS    [Toc]    [Back]

       /sbin/sync

DESCRIPTION    [Toc]    [Back]

       The sync utility runs the  sync  function,  which  flushes
       (writes)  system metadata and data from all unwritten memory
 buffers  to  disk.   For  example,  the  data  flushed
       includes,  for UFS, modified inodes and delayed block I/O.

       Other commands that bring the system  down,  such  as  the
       shutdown command, issue their own sync functions.

       Use  this  sync  utility  to  ensure file system integrity
       should you need to stop the system under  unusual  circumstances.


       Note  that the writing of buffers to disk, although scheduled,
 may not be complete when the utility exits.
