ntp-wait - 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: 100

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: 6

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.

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 Thank you.
