NAME¶
ntp-wait - Wait for ntpd to stabilize the system clock
SYNOPSIS¶
ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]]
All arguments must be options.
DESCRIPTION¶
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.
OPTIONS¶
- -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.
EXIT STATUS¶
One of the following exit values will be returned:
- 0 (EXIT_SUCCESS)
-
Successful program execution. - 1 (EXIT_FAILURE)
-
The operation failed or the command syntax was not valid. - 70 (EX_SOFTWARE)
-
libopts had an internal operational error. Please report it to autogen-users@lists.sourceforge.net. Thank you.
