Minimal Chat with Netcat

Recently I was setting up another computer and I wanted to set it up the same as my current machine and I wanted to send a list of my packages installed and didn’t want to send and email, Facebook message, or open GoogleDrive, so I did some research.
Find the IP address of the computers
ip address show | grep -i inet
“ip address show” is a way to find the ip address of a computer, and then piping it to grep and filtering down to strings containing inet cuts down some of the noise.
Setup the first computer
nc -l 55555
This starts netcat in listen mode for the port 55555.
Setup the next computer
nc <ipaddress_of_first_computer> 55555
This opens netcat to the other computer.
Type some information in one of the terminals and press enter and it will show in the other terminal.
Getting installed packages using pacman
pacman -Qqe > pkglist.txt
pacman -S - < pkglist.txt
Will install packages from a list.
