.TH AMQ 8 "25 April 1989"
.SH NAME
amq \- automounter query tool
.SH SYNOPSIS
.B amq
[
.BI \-fmpsuvwHTU
] [
.BI \-h " hostname"
] [
.BI \-l " log_file"
] [
.BI \-x " log_options"
] [
.BI \-D " debug_options"
] [
.BI \-M " mountmap entry"
] [
.BI \-P " program_number"
] [
.I directory
] .\|.\|.
.SH DESCRIPTION
.B Amq
provides a simple way of determining the current state of
.B amd
program.
Communication is by
.SM RPC.
Three modes of operation are supported by the current protocol.  By default
a list of mount points and auto-mounted filesystems is output.  An
alternative host can be specified using the
.I \-h
option.
.LP
If
.I directory
names are given, as output by default, then per-filesystem
information is displayed.
.SH OPTIONS

.TP
.B \-f
Ask the automounter to flush the internal caches.

.TP
.BI \-h " hostname"
Specify an alternate host to query.  By default the local host is used.  In
an
.SM HP-UX
cluster, the root server is queried by default, since that is the system on
which the automounter is normally run.

.TP
.BI \-l " log_file"
Tell amd to use
.I log_file
as the log file name.  For security reasons, this must be the same log file
which amd used when started.  This option is therefore only useful to
refresh amd's open file handle on the log file, so that it can be rotated
and compressed via daily cron jobs.

.TP
.B \-m
Ask the automounter to provide a list of mounted filesystems, including the
number of references to each filesystem and any error which occurred while
mounting.

.TP
.B \-p
Return the process ID of the remote or locally running amd.  Useful when you
need to send a signal to the local amd process, and would rather not have to
search through the process table.  This option is used in the
.I ctl-amd
script.

.TP
.B \-s
Ask the automounter to provide system-wide mount statistics.

.TP
.B \-u
Ask the automounter to unmount the filesystems named in
.I directory
instead of providing
information about them.  Unmounts are requested, not forced.  They merely
cause the mounted filesystem to timeout, which will be picked up by
.BR amd 's
main scheduler thus causing the normal timeout action to be taken.

.TP
.B \-v
Ask the automounter for its version information.  This is a subset of the
information output by
.BR amd 's
.I -v
option.

.TP
.B \-w
Translate a full pathname as returned by
.IR getpwd (3)
into a short
.B Amd
pathname that goes through its mount points.   This option requires that
.B Amd
is running.

.TP
.BI \-x " log_options"
Ask the automounter to use the logging options specified in
.I log_options
from now on.

.TP
.BI \-D " log_options"
Ask the automounter to use the debugging options specified in
.I debug_options
from now on.

.TP
.B \-H
Display short usage message.

.TP
.BI \-M " map_ent"
Pass a mount map entry to
.B amd
and wait for it to be evaluated, possible causing a mount.  This option is
highly insecure.  By default, amd and amq do not support it.  You have to
configure am-utils with
.I \-\-enable\-amq\-mount
to enable this option.

.TP
.BI \-P " program_number"
Contact an alternate running amd that had registered itself on a different
RPC
.I program_number
and apply all other operations to that instance of the automounter.  This is
useful when you run multiple copies of amd, and need to manage each
one separately.  If not specified, amq will use the default program number
for amd, 300019.  For security reasons, the only alternate program numbers
amd can use range from 300019 to 300029, inclusive.

.TP
.B \-T
Contact
.B amd
using the TCP transport only.  Normally
.B amq
will try TCP, and if that failed, will try UDP.

.TP
.B \-U
Contact
.B amd
using UDP (connectionless) transport only.  Normally
.B amq
will try TCP, and if that failed, will try UDP.

be in the /etc/rpc database.
