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