Manual page for SYNC(8)
sync - update the super block
SYNOPSIS
/bin/sync
DESCRIPTION
Sync
executes the
sync
system primitive.
Sync
can be called to insure that all disk writes have been completed before the
processor is halted in a way not suitably done by
reboot.8
or
halt.8
Generally, it is preferable to use
reboot
or
halt
to shut down the system,
as they may perform additional actions
such as resynchronizing the hardware clock
and flushing internal caches before performing a final
sync.
See
sync.2
for details on the system primitive.
SEE ALSO
sync(2), fsync(2), halt(8), reboot(8), update(8)
