Terminal (CLI) secrets

Command Line basics

$ ls -a     # lists all contents of a directory, including hidden files and directories
$ ls -l     # lists all contents in long format
$ ls -t     # orders files and directories by the time they were last modified
Multiple options can be used together, like ls -alt
From the command line, you can also copy, move, and remove files and directories:
$ cp        # copies files
$ mv          # moves and renames files
$ rm          # removes files
$ rm -r       # removes directories
