Wait for ntpd to stabilize the system clock


ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]]

All arguments must be options.


ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not yet produced a synchronized and stable system clock.

ntp-wait will do this quietly, unless the -v flag is provided. This can be useful at boot time, to delay the boot sequence until after ntpd -g has set the time.


-n number, --tries=number

Number of times to check ntpd. This option takes an integer number as its argument. The default number for this option is:


       The maximum number of times we will check ntpd to see if
       it has been able to synchronize and stabilize the system clock.

-s secs-between-tries, --sleep=secs-between-tries

How long to sleep between tries. This option takes an integer number as its argument. The default secs-between-tries for this option is:


       We will sleep for secs-between-tries after each query
       of ntpd that returns "the time is not yet stable".

-v, --verbose

Be verbose.

       By default, ntp-wait is silent.
       With this option, ntp-wait will provide status information.

-?, --help

Display usage information and exit.

-!, --more-help

Pass the extended usage information through a pager.

-v [{v|c|n --version [{v|c|n}]}]

Output version of program and exit.  The default mode is `v', a simple version.  The `c' mode will print copyright information and `n' will print the full copyright notice.

Exit Status

One of the following exit values will be returned:


Successful program execution.


The operation failed or the command syntax was not valid.


libopts had an internal operational error.  Please report it to autogen-users@lists.sourceforge.net.  Thank you.
