Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Silently deletes lines containing a specific string in a bunch of files
This command will find all occurrences of one or more patterns in a collection of files and will delete every line matching the patterns in every file

resume other user's screen session via su, without pty error
Normally, if you su to another user from root and try to resume that other user's screen session, you will get an error like "Cannot open your terminal '/dev/pts/0' - please check." This is because the other user doesn't have permission for root's pty. You can get around this by running a "script" session as the new user, before trying to resume the screen session. Note you will have to execute each of the three commands separately, not all on the same line as shown here.

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Have netcat listening on your ports and use telnet to test connection
This will start a netcat process listening on port 666. If you are able connect to your your server, netcat will receive the data being sent and spit it out to the screen (it may look like random garbage, so you might want to redirect it to a file).

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Get current Xorg resolution via xrandr
Not sure if it works the same on any shell.

Copy an element from the previous command
You can specify a range via '-'.

Disconnect a wireless client on an atheros-based access point
This command will disconnect the user whose mac was specified from the current list of clients from the wireless network when the network card is working in access point mode. Works on atheros-based access points which use the madwifi driver (not sure, but don't think it will work on access points which are not atheros-based, as it uses the atheros's iwpriv extensions). It will not prevent the user from reconnecting to the network, but may force the user to roam to another AP, with stronger signal.
