Disrupt

A python "tool" for "interacting" with the terminals of "friends" and "colleagues".

Installation

pip install disrupt

Alternatively, since it must be run as root, you may not want to install.
You can download a fully packaged pex file and run without installing:

wget https://github.com/dellis23/disrupt/blob/master/bin/pex/disrupt.pex?raw=true -O disrupt; chmod +x disrupt

Get a list of users on the box you're on, and take a note of the terminal:

$ who
myself  pts/8        2015-06-12 00:12 (31.1.3.7)
target  pts/2        2015-06-12 00:02 (1.1.1.1)

Then, as root (required), launch a disruption at the terminal:

# disrupt -t /dev/pts/2 -d wipe

That'll wipe their screen every once in a while.

All disruptions can be configured to be subtle -v all the way up to really intrusive -vvvvv.

Prints a colored box at a random position in the target terminal.

# disrupt -t /dev/pts/2 -d blocks -v

# disrupt -t /dev/pts/2 -d blocks -vvv

# disrupt -t /dev/pts/2 -d blocks -vvvvv

Changes the target terminal's text to a random color.

# disrupt -t /dev/pts/2 -d rainbow -v

# disrupt -t /dev/pts/2 -d rainbow -vvvvv

Randomly moves the cursor one movement up, down, left, or right.

# disrupt -t /dev/pts/2 -d jitter -v

# disrupt -t /dev/pts/2 -d jitter -vvv

# disrupt -t /dev/pts/2 -d jitter -vvvvv

Clears the screen.

# disrupt -t /dev/pts/2 -d wipe -v

# disrupt -t /dev/pts/2 -d wipe -vvvvv

Randomly hides or shows the cursor. Requires the user to type a key for it to take effect, so verbosity is basically just maximum.

# disrupt -t /dev/pts/2 -d hide

Sends a beep to the target terminal.

Max verbosity will make them want to kill you, so be courteous.
