NAME
sync - Updates the inode table and writes buffered files to the disk
SYNOPSIS
sync
DESCRIPTION
The sync command runs the sync system primitive. sync writes all un-
written system buffers to disk. This includes modified inodes and de-
layed block I/O.
Commands that bring the system down, such as the shutdown command, is-
sue their own sync calls. Use the sync command if the system must be
stopped under unusual circumstances, to ensure file system integrity.
Note that the writing of unwritten buffers, although scheduled, is not
necessarily complete upon return from sync. In some circumstances it
may be appropriate to issue consecutive sync commands.
