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

SYNOPSIS
       /sbin/sync

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

       Other commands that bring the system down, such as  the	shutdown  com‐
       mand, 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.
