NAME
       syncer - periodically sync for file system integrity

SYNOPSIS
       [seconds] directory ...]

DESCRIPTION
       is  a  program  that periodically executes 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

       also updates the file if it does not match current kernel mount	infor‐
       mation.

   Options
       recognizes the following options:

	      Cause	to  not	 update	 the file.  Use of this option is pro‐
			vided for  special  cases  of  backward	 compatilibity
			only, and is strongly discouraged.  This option may be
			removed in a future release.

	      Open directories for cache benefit.
			All directories must be specified by their  full  path
			name.	If  the option is not used, no directories are
			opened.

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