 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 argument 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.

 AUTHOR
      syncer was developed by the University of California, Berkeley and HP.
