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. AUTHORS
