Neither iwconfig nor iwlist seem to be able to do this for me.

Run nm-tool | grep \*. That should show just the line with the SSID you are connected to.

Thanks that's exactly what I needed. To get just the name:nm-tool |grep --only-matching '*[^ ][^:]*' |sed 's/^*//' –  John Baber Mar 29 '12 at 16:09

nmcli -t -f active,ssid dev wifi is easier to parse. The ssid is unfortunately encapsulated in some useless quotes though. –  geirha Mar 29 '12 at 16:48

Or: nmcli -t -f active,ssid dev wifi | egrep '^yes' | cut -d\' -f2 (which will work as long as the SSID doesn't contain any ' characters) –  Scott Severance Mar 30 '12 at 7:43

Although the question has already been answered, the iwconfig tool does display the ESSID of the currently connected Wifi network. Perhaps it does not work with connections managed through NetworkManager but it works with interfaces managed through ifup/ifdown:

iwconfig | grep wlan0

lists:

wlan0     IEEE 802.11bgn  ESSID:"ahoi"

Typing iwconfig only can do the purpose too :-) thanks for sharing this command :-) –  Suhaib Mar 30 '13 at 18:22

iwgetid provides the ssid

iwgetid -r gives just the name.

In a Bash script try something like myssid=$(iwgetid -r) to put it in a variable

Thanks! Looks much better than the commonly recommended iw/iwlan+sed/grep solutions. –  Rob W Mar 19 at 12:37
