To retrieve the full output of a command run in screen without scrolling, you have a few options:

1. Use screen's scrollback buffer

• Enter copy mode in screen by pressing: Ctrl + A, then [ (left square bracket).
• Now you can navigate using:
  • Arrow keys or Page Up/Page Down to scroll.
  • / to search forward, ? to search backward.
• To copy text:
  • Press Space to mark the start.
  • Move the cursor to the end.
  • Press Enter to copy the selected text to the clipboard.
• Exit copy mode by pressing Esc or Ctrl + C.

2. Redirect output to a file

If you want to avoid scrolling entirely, redirect the command's output to a file when running it:

bash
Copy
your_command > output.txt 2>&1

• This saves both stdout and stderr to output.txt.
• Open the file later with less, cat, or any text editor.

3. Use tee to save and view output

If you want to see the output in real-time and save it:

bash
Copy
your_command | tee output.txt

• This displays the output on the screen and saves it to output.txt.

4. Increase screen's scrollback buffer

If you want to keep more output in memory for scrolling:

• Add this to your ~/.screenrc:

  text
  Copy
  defscrollback 10000

• Or start screen with:

  bash
  Copy
  screen -h 10000

• This sets the scrollback buffer to 10,000 lines.
