3. SYNOPSIS
ntpwait [-vV] [-n number] [-s secs]
4. DESCRIPTION
The ntpwait program blocks until ntpd is in synchronized state. This
can be useful at boot time, to delay the boot sequence until after "ntpd
-g" has set the time.
ntpwait will send at most number queries to ntpd(8), sleeping
for secs seconds after each status return that says ntpd(8) has not
yet produced a synchronized and stable system clock.
ntpwait will do this quietly, unless the -v flag is provided.
5. OPTIONS
-nnumber,--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.
-ssecs-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,
ntpwaitis silent. With this option,ntpwaitwill provide status information, including time to synchronization in seconds. -V,--version-
Print the version string and exit.
