Core Unix commands

Most unix commands have super short names, which make them quick to type but annoying to learn. Major file system related commands include:

pwd: Print working directory ls: List files and directories cd: Change directory mkdir: Make a new directory rm: Remove files and directories (delete)zh cp: Copy files (source > destination) mv: Move files or dirs (basically re-name) nano: A wee text editor (very basic but always available) curl: Download files from web wget: DOwnload files from the web tar -zxvf: untar (unpackage) Tr archive files gunzip: UnZip files $PATH: The places (dirs) to look for programs.
