 syncer(1M)                                                       syncer(1M)

 NAME    [Toc]    [Back]
      syncer - periodically sync for file system integrity

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/syncer [seconds] [-s] [-d directory ...]

 DESCRIPTION    [Toc]    [Back]
      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    [Toc]    [Back]
      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

           -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    [Toc]    [Back]
      syncer was developed by the University of California, Berkeley and HP.
