Bash Scroll Won't Work

If you’re encountering difficulties scrolling through content in your Bash terminal while using the more or less commands, there are several troubleshooting steps you can take to address the issue. These commands are designed to display the contents of files or command outputs one screen at a time. If scrolling isn’t functioning as expected, consider the following solutions:

1. Utilize Keyboard Shortcuts

When using the more or less commands, you can employ the following keyboard shortcuts to navigate through the displayed content:

  • Spacebar: Move forward one page.
  • Enter: Move forward one line.
  • B: Move backward one page.
  • Q: Quit and exit the display.
  • /your_search_term: Search for a specific term within the content (replace your_search_term with the actual term).

2. Verify Arrow Key Functionality

Use the arrow keys (up and down) to scroll through the content. If the arrow keys are not responsive, ensure that your terminal settings are correctly configured.

3. Examine Terminal Emulator Settings

If you’re utilizing a specific terminal emulator (such as Terminal on macOS, GNOME Terminal on Linux, or PuTTY on Windows), confirm that the emulator settings are not causing issues with keyboard inputs. You may need to adjust keyboard settings within the terminal emulator preferences.

4. Check for Interactive Mode

Occasionally, scrolling may not work as anticipated when the output is not in “interactive mode” (for instance, when output is redirected to a file or another command). If you’re using a pipe (|) to send output to more or less, attempt running the command without the pipe to determine if the problem persists.

5. Ensure Terminal Window Size

Ensure that your terminal window is sufficiently large to accommodate the displayed content. If the content is shorter than the terminal window, scrolling may not be necessary.

6. Inspect for Errors

If you’re attempting to view the output of a command and encounter errors or issues with the command itself, it could impact the behavior of more or less. Confirm that the command is functioning as intended.

7. Check for Control Characters

In certain cases, control characters or special formatting within a file might affect scrolling behavior. If the content appears distorted or fails to respond to scrolling, it’s possible that the file contains non-printable characters.

8. Reset the Terminal

If none of the aforementioned solutions resolve the problem, consider restarting your terminal emulator or resetting your terminal session to see if that resolves the issue.

Remember that both more and less are widely used terminal commands and should function correctly in most scenarios. If you continue to encounter problems after attempting these steps, there could be specific issues with your terminal configuration or system setup that require further investigation.
