SYNC(1) SysV SYNC(1)
NAME
sync - forces write to disk
SYNOPSIS
sync
DESCRIPTION
The sync command executes the sync system primitive. It flushes all
previously unwritten system buffers out to disk, thus assuring that all
file modifications up to that point are saved.
The sync operation is not actually necessary on DOMAIN hardware, because
the system buffers are automatically written to disk at shutdown.
Nevertheless, we provide it in the interest of ensuring compatibility.
