update(8)update(8)NAMEupdate - Periodically updates the file system
SYNOPSIS
/sbin/update
DESCRIPTION
The update command flushes data from memory to disk every 30 seconds.
This ensures that the file system is up to date in the event of a sys‐
tem crash. This command is provided as a statically-linked executable
in the /sbin directory.
The setting of the smoothsync_age attribute of the vm kernel subsystem
overrides the default timing of the update command. See sys_attrs_vm(5)
for more information about this attribute. Refer to the System Configu‐
ration and Tuning and System Administration manuals for general infor‐
mation about configuring and tuning the system.
