sync — Update the Superblock
Synopsis
sync
Description
The sync command executes the sync system primitive. If the system is to be stopped, sync must be called to ensure file system integrity. It flushes all previously unwritten system buffers out to disk, thus assuring that all file modifications up to that point are saved. See sync(2) for details.
Note
If you have done a write to a file on a remote machine in a Remote File Sharing environment, you cannot use sync to force buffers to be written out to disk on the remote machine. sync writes only local buffers to local disks.
