SYNC 8 ""
C 4 NAME
sync - update the super block
SYNOPSIS
/etc/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.
