Mastering the Linux command line interface (CLI) can boost efficiency and flexibility. We will introduce a set of essential Linux CLI Shortcuts.

Essential Linux CLI Shortcuts:

  • Tab Auto-completion: Quickly complete commands, file paths, or directory names by pressing the Tab key.
  • Ctrl + C: Instantly stop a running process or command with this keyboard shortcut.
  • Ctrl + Z: Suspend a process, allowing it to be resumed or terminated later.
  • Ctrl + D: Signals the end of input, commonly used to close a terminal session.
  • Ctrl + R: Search through command history to easily find and re-run a specific command.
  • Ctrl + L: Clear the terminal screen, creating a cleaner workspace.
  • Ctrl + A: Move the cursor to the beginning of the line.
  • Ctrl + E: Move the cursor to the end of the line.
  • Ctrl + K: Delete everything after the cursor.
  • Ctrl + U: Delete the entire command line.
  • Ctrl + Y: Restore (paste back) text deleted by Ctrl+K or Ctrl+U.
    • Y stands for “yank” — before the clipboard existed in Windows, the command prompt era used “yank” for this operation.
