iwgetid - Report ESSID, NWID or AP/Cell Address of wireless network
iwgetid [interface] [--raw] [--scheme] [--ap] [--freq]
[--mode] [--protocol] [--channel]
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 iwconfig
, but iwgetid
is easier to integrate
in various scripts.
By default, iwgetid
will print the ESSID
of the device, and if the
device doesn't have any ESSID it will print its NWID
The default formatting output is pretty-print.
- This option disables pretty-printing of the information.
This option is orthogonal to the other options (except --scheme),
so with the appropriate combination of options you can print the raw
ESSID, AP Address or Mode.
This format is ideal when storing the result of iwgetid as a variable in
Shell or Perl scripts or to pass the result as an argument
on the command line of iwconfig.
- 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).
The resulting output is a valid Pcmcia scheme identifier (that may be used
as an argument of the command cardctl scheme). This format is also
ideal when using the result of iwgetid as a selector in Shell or
Perl scripts, or as a file name.
- Display the MAC address of the Wireless Access Point
or the Cell.
- Display the current frequency or channel used
by the interface.
- Display the current channel used by the interface.
The channel is determined using the current frequency and the frequency
list provided by the interface.
- Display the current mode of the interface.
- Display the protocol name of the interface. This
allows to identify all the cards that are compatible with each other and
accept the same type of configuration.
This can also be used to check Wireless Extension support on the
interface, as this is the only attribute that all drivers supporting
Wireless Extension are mandated to support.
