Linux Tutorial

Before we begin our lessons, there are a couple of things about Linux that I feel I should point out. First, Linux is case-sensitive (unlike Windows), which means that a file named “hey” is different than a file named “Hey”. Second, Linux does not like having spaces in filenames. To “separate” words in the name of a file, you can do a few different things:

• FileNameOne – you can capitalize the first letter of each word
• file-name-two – you can put hyphens between each word
• file_name_three – you can put underscores between each word

• Lesson 1 – Logging in and out
  • ssh
• Lesson 2 – Permissions
  • ls
  • chown
  • chgrp
    • groups
    • newgrp
  • chmod
• Lesson 3 – Moving around in the filesystem
  • cd
  • pwd
• Lesson 4 – Viewing/Searching for Files
  • more
  • tail
  • find
  • grep
• Lesson 5 – Editing Files
  • emacs
  • vi
• Lesson 6 – SFTP
  • sftp
• More Commands
