Didn't fetch my password with `sudo nmcli ...`, only with `nmcli ...`

Here's an example:

Your command from here:

m ~ % sudo nmcli -s -g 802-11-wireless-security.psk connection show $SSID | grep -q . && echo 'Password found'
m ~ %

Since I'm not running wifi-password as root, it puts sudo on.

Removing the sudo:

m ~ % nmcli -s -g 802-11-wireless-security.psk connection show $SSID | grep -q . && echo 'Password found' 
Password found

One thing though, is that nmcli has this functionality:

m ~ % nmcli device wifi show-password 
SSID: [CLIPPED]
Security: WPA
Password: [CLIPPED FOR GITHUB]

Hey @mattalexx,

This seems strange. I can't quite remember why I am running that nmcli command with sudo because I just ran:

nmcli -s -g 802-11-wireless-security.psk connection show MY_SSID

and it gave me the password. Unlike on your system, the above command returns the password even when using sudo on my system (Arch Linux with NetworkManager version 1.32.12-1).

I'm starting to think that sudo might not be needed at all, but I'll have to take a further look as to why I initially included sudo in that command when I wrote that function.

I do find it odd that running that command with sudo does not work for you. Maybe it has something to do with permissions? Does running the command with sudo output anything at all such as errors?
