Simple one-way clipboard sync

I needed a simple way to continuously transfer the clipboard from one computer to another, so I hacked together these two oneliners.

Sender

# replace 10.0.0.1 with receiver's IP address
while true; do if [ "$last" != "$(xclip -o)" ]; then last="$(xclip -o )"; xclip -o | nc -vc 10.0.0.1 9999; fi; sleep 1; done

Receiver

while true ; do nc -vl 9999 | xclip -i -selection clipboard ; done

If one of the machines is on macOS, replace xclip -o with pbpaste or xclip -i -selection clipboard with pbcopy.

Warning

Only use this on trusted networks and with trusted machines, the clipboard contents are transmitted unencrypted!
