<H2>DESCRIPTION</H2>
|
|
|
|
<B>iwgetid</B>
|
|
|
|
is used to find out the NWID, ESSID or AP/Cell Address of the wireless
|
|
network that is currently used. The information reported is the same
|
|
as the one shown by
|
|
<B>iwconfig</B>, but <B>iwgetid</B>
|
|
|
|
is easier to integrate in various scripts.
|
|
<BR>
|
|
|
|
By default,
|
|
<B>iwgetid</B>
|
|
|
|
will print the
|
|
<I>ESSID</I>
|
|
|
|
of the device, and if the device doesn't have any ESSID it will print
|
|
its
|
|
<I>NWID</I>.
|
|
|
|
<BR>
|
|
|
|
The default formatting output is pretty-print.

<H2>OPTIONS</H2>
|
|
|
|
<DL COMPACT>
|
|
<DT id="1"><B>--raw</B>
|
|
|
|
<DD>
|
|
This option disables pretty-printing of the information. This option
|
|
is orthogonal to the other options (except
|
|
<B>--scheme</B>),
|
|
|
|
so with the appropriate combination of options you can print the raw
|
|
ESSID, AP Address or Mode.
|
|
<BR>
|
|
|
|
This format is ideal when storing the result of iwgetid as a
|
|
variable in
|
|
<I>Shell</I>
|
|
|
|
or
|
|
<I>Perl</I>
|
|
|
|
scripts or to pass the result as an argument on the command line of
|
|
<B>iwconfig</B>.
|
|
|
|
<DT id="2"><B>--scheme</B>
|
|
|
|
<DD>
|
|
This option is similar to the previous one, it disables
|
|
pretty-printing of the information and removes all characters that are
|
|
not alphanumerics (like space, punctuation and control characters).
|
|
<BR>
|
|
|
|
The resulting output is a valid Pcmcia scheme identifier (that may be
|
|
used as an argument of the command
|
|
<B>cardctl scheme</B>).
|
|
|
|
This format is also ideal when using the result of iwgetid as a
|
|
selector in
|
|
<I>Shell</I>
|
|
|
|
or
|
|
<I>Perl</I>
|
|
|
|
scripts, or as a file name.
|
|
<DT id="3"><B>--ap</B>
|
|
|
|
<DD>
|
|
Display the MAC address of the Wireless
|
|
<I>Access Point</I>
|
|
|
|
or the
|
|
<I>Cell</I>.
|
|
|
|
<DT id="4"><B>--freq</B>
|
|
|
|
<DD>
|
|
Display the current
|
|
<I>frequency</I>
|
|
|
|
or
|
|
<I>channel</I>
|
|
|
|
used by the interface.
|
|
<DT id="5"><B>--channel</B>
|
|
|
|
<DD>
|
|
Display the current
|
|
<I>channel</I>
|
|
|
|
used by the interface. The channel is determined using the current
|
|
frequency and the frequency list provided by the interface.
|
|
<DT id="6"><B>--mode</B>
|
|
|
|
<DD>
|
|
Display the current
|
|
<I>mode</I>
|
|
|
|
of the interface.
|
|
<DT id="7"><B>--protocol</B>
|
|
|
|
<DD>
|
|
Display the
|
|
<I>protocol name</I>
|
|
|
|
of the interface. This allows to identify all the cards that are
|
|
compatible with each other and accept the same type of configuration.
|
|
<BR>
|
|
|
|
This can also be used to
|
|
<I>check Wireless Extension support</I>
|
|
|
|
on the interface, as this is the only attribute that all drivers
|
|
supporting Wireless Extension are mandated to support.
