sync(ADM)


sync -- write all changes to disk

Syntax

sync [ file ... ]

Description

Without arguments, sync executes the sync system primitive to write all changes to the storage medium. If the system is to be stopped, sync must be called to ensure filesystem integrity. Note that shutdown(ADM) automatically calls sync before shutting down the system.

If you specify the filenames (file ...) of regular files or block devices for which you have write permission, sync executes the fsync system primitive to write out changes associated with just those files or devices.

The usage of sync with filename arguments is not part of any currently supported standard; it is an extension of AT&T System V provided by the Santa Cruz Operation, Inc.
