I want to find the password for the wireless network that I am currently connected to (and I entered the password when connecting to the network). How can I do this in Ubuntu?

I went to "connection information" and didn't find the password. – Anderson Green Jun 27 '12 at 20:18

left click the connections icon at the top right. Choose edit connections and then choose edit on the connection you need and click the wireless security...

and click the 'show password'checkbox

Ah, my command-line ways were betrayed by my solution :) I like this one better, FWIW. – roadmr Jun 27 '12 at 22:44
    
Well I like both with a preference to command line @roadmr :D – Rinzwind Jun 28 '12 at 7:17

Open a terminal (press Ctrl+Alt+T), then type sudo cat /etc/NetworkManager/system-connections/<your-SSID> (of course, substitute <your-SSID> with your network's name) and look for a field named psk. This should be your password;

psk=notreallymypassword

if you want to do this with the command line. The wireless network configuration files are saved in /etc/NetworkManager/system-connections/ directory.

cd /etc/NetworkManager/system-connections/
ls
grep -e '^psk=' <YOUR-NETWORK-NAME>

here is a one liner to make @David Foerster answer more useful

MYCWD=`pwd`; cd /etc/NetworkManager/system-connections/ ; sudo grep -e '^psk=' * | less ; cd $MYCWD
