SSH
SSH (Secure SHell) is a network protocol that enables two computers to communicate and share data securely over insecure networks through encrypted connections. 1
SSH is often used to "login" and perform operations on remote computers, but can also be used for transferring data. 1
Basic commands:
ssh <user>@pc<#>.cs.ucdavis.edu
You can run a command on remote machines and pipe (command) the result:
ssh noah@pc17.cs.ucdavis.edu ls | grep Downloads
