NAME

syncer - periodically sync for ﬁle system integrity

SYNOPSIS

/usr/sbin/syncer

[ seconds ][-s][-d directory ... ]

DESCRIPTION

syncer is a program that periodically executes

sync() at an interval determined by the input argu-

ment seconds (see sync(2)). If seconds is not speciﬁed, the default interval is every 30 seconds. This

ensures that the ﬁle system is fairly up-to-date in case of a crash. This command should not be executed

directly, but should be executed at system boot time via startup script

/sbin/init.d/syncer

syncer also updates the /etc/mnttab ﬁle if it does not match current kernel mount information.

Options

syncer recognizes the following options:

-s Cause syncer to not update the /etc/mnttab

ﬁle. Use of this option is provided for

special cases of backward compatilibity only, and is strongly discouraged. This option

may be removed in a future release.

-d Open directories for cache beneﬁt. All directories must be speciﬁed by their full path

name. If the -d option is not used, no directories are opened.
