How many times happen to have a guest that asks you about the wireless password and you cannot remember it? On Ubuntu Linux, you can easily retrieve the wireless password like this:
[code language=”bash”]
sudo cat /etc/NetworkManager/system-connections/YOUR_NETWORK_NAME_HERE | grep "psk="
[/code]
The output will be something like:
[code language=”bash”]
psk=myultrasecretpassword
[/code]
