Command Line Crash Course For Beginners | Terminal Commands

description
This is a course for beginners to learn how to navigate the terminal/command line. I tried to make it as OS agnostic as possible, but if you are on Windows, I suggest using something like "Git Bash". ⭐ Check out Agora! https://bit.ly/3bLM8Iu 💻 Gist With All Commands: https://gist.github.com/bradtraversy/cc180de0edee05075a6139e42d5f28ce 👇 Follow Traversy Media On Social Media: Twitter: https://twitter.com/traversymedia Instagram: https://www.instagram.com/traversymedia Linkedin: https://www.linkedin.com/in/bradtraversy Timestamps: 0:00 - Intro 0:50 - Agora Sponsor 1:34 - Slides Start 2:00 - Why Learn The Command Line? 5:43 - Command Line vs Terminal vs Shell 8:25 - Let's Talk About Windows 10:30 - Gist File 12:20 - Up & Down Arrow 12:44 - Tab Key 13:08 - Keyboard Shortcuts 14:11 - man 15:11 - whoami 15:17 - date 15:21 - clear 15:47 - pwd 16:09 - ls 18:13 - cd 19:35 - open, start, xdg-open 20:25 - mkdir 20:55 - touch 21:22 - rm 22:31 - rm -r 23:48 - cp 24:28 - mv 27:46 - cat 29:14 - RIght Angle Bracket (piping) 30:32 - less 31:00 - head 31:21 - tail 32:01 - nano 33:04 - echo 33:53 - grep 36:10 - find 38:03 - More On Piping 39:44 - ln (symlinks) 41:36 - tar 43:45 - history
