NAME

sync − update the super block

SYNOPSIS

sync

DESCRIPTION

Sync executes the sync system primitive.  If the system is to be stopped, sync must be called to insure file system integrity.  It will flush all previously unwritten system buffers out to disk, thus assuring that all file modifications up to that point will be saved.  See sync(2) for details.

EXAMPLE

sync

should be typed to flush all internal disk buffers, before bringing down the system.
