When I first started with the Raspberry Pi, navigating the command line in Linux was quite frustrating. After entering a long command, I realized I didn’t have the necessary permissions, and had to move the cursor back to the start of the line… Once I learned the keyboard shortcuts for the command line, not only did my efficiency improve, but I also started to enjoy this method of operation.
Commonly Used
-
Ctrl+Left/Right Arrow: Jump between words
-
Ctrl+a: Move to the beginning of the line
-
Ctrl+e: Move to the end of the line
-
Ctrl+u: Delete text before the cursor (also has cut functionality)
-
Ctrl+k: Delete text after the cursor (also has cut functionality)
-
Ctrl+L: Clear the screen
-
Ctrl+y: Paste content cut from Ctrl+u or Ctrl+k
-
Ctrl+w: Delete the word before the cursor
-
Alt-d: Delete the word from the cursor to the end of the line
Notes
-
Ctrl-k: Press and hold the Ctrl key, then press k;
-
Alt-k: Press and hold the Alt key, then press k;
