.SH NAME
\f\*[B-Font]ntp-wait\fP
\- Wait for ntpd to stabilize the system clock
.SH SYNOPSIS
\f\*[B-Font]ntp-wait\fP
.\" Mixture of short (flag) options and long options
[\f\*[B-Font]\-flags\f[]]
[\f\*[B-Font]\-flag\f[] [\f\*[I-Font]value\f[]]]
[\f\*[B-Font]\-\-option-name\f[][[=| ]\f\*[I-Font]value\f[]]]
.sp \n(Ppu
.ne 2
All arguments must be options.
.sp \n(Ppu
.ne 2
.SH DESCRIPTION
\f\*[B-Font]ntp-wait\fP
will send at most
\f\*[I-Font]num-tries\f[]
queries to
\fCntpd\f[]\fR(8)\f[],
sleeping for
\f\*[I-Font]secs-between-tries\f[]
after each status return that says
\fCntpd\f[]\fR(8)\f[]
has not yet produced a synchronized and stable system clock.
.sp \n(Ppu
.ne 2
\f\*[B-Font]ntp-wait\fP
will do this quietly, unless the
\f\*[B-Font]\-v\f[]
flag is provided.
This can be useful at boot time, to delay the boot sequence until after
\f\*[I-Font]ntpd\f[] \f\*[I-Font]\-g\f[]
has set the time.
.SH "OPTIONS"
.TP
.NOP \f\*[B-Font]\-n\f[] \f\*[I-Font]number\f[], \f\*[B-Font]\-\-tries\f[]=\f\*[I-Font]number\f[]
Number of times to check ntpd.
This option takes an integer number as its argument.
The default
\f\*[I-Font]number\f[]
for this option is:
.ti +4
100
.sp
The maximum number of times we will check \fBntpd\fP to see if
it has been able to synchronize and stabilize the system clock.
.TP
.NOP \f\*[B-Font]\-s\f[] \f\*[I-Font]secs\-between\-tries\f[], \f\*[B-Font]\-\-sleep\f[]=\f\*[I-Font]secs\-between\-tries\f[]
How long to sleep between tries.
This option takes an integer number as its argument.
The default
\f\*[I-Font]secs\-between\-tries\f[]
for this option is:
.ti +4
6
.sp
We will sleep for \fIsecs-between-tries\fP after each query
of \fBntpd\fP that returns "the time is not yet stable".
.TP
.NOP \f\*[B-Font]\-v\f[], \f\*[B-Font]\-\-verbose\f[]
Be verbose.
.sp
By default, \fBntp-wait\fP is silent.
With this option, \fBntp-wait\fP will provide status information.
.TP
.NOP \f\*[B-Font]\-\&?\f[], \f\*[B-Font]\-\-help\f[]
Display usage information and exit.
.TP
.NOP \f\*[B-Font]\-\&!\f[], \f\*[B-Font]\-\-more-help\f[]
Pass the extended usage information through a pager.
.TP
.NOP \f\*[B-Font]\-v\f[] [{\f\*[I-Font]v|c|n\f[] \f\*[B-Font]\-\-version\f[] [{\f\*[I-Font]v|c|n\f[]}]}]
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.
.PP
.SH "EXIT STATUS"
One of the following exit values will be returned:
.TP
.NOP 0 " (EXIT_SUCCESS)"
Successful program execution.
.TP
.NOP 1 " (EXIT_FAILURE)"
The operation failed or the command syntax was not valid.
.TP
.NOP 70 " (EX_SOFTWARE)"
libopts had an internal operational error. Please report
it to autogen-users@lists.sourceforge.net. Thank you.
