Bash Shortcuts

Bash provides several shortcuts and key combinations that can help you work more efficiently in the command line. Here are some commonly used Bash shortcuts:

1. Moving the cursor:

• Ctrl + A: Move the cursor to the beginning of the line.
• Ctrl + E: Move the cursor to the end of the line.
• Alt + F or Alt + →: Move the cursor forward one word.
• Alt + B or Alt + ←: Move the cursor backward one word.

1. Editing the command line:

• Ctrl + U: Clear the line before the cursor.
• Ctrl + K: Clear the line after the cursor.
• Ctrl + W: Delete the word before the cursor.
• Ctrl + Y: Paste the previously deleted text.
• Ctrl + L: Clear the screen (similar to the clear command).
• Ctrl + C: Cancel the currently running command.
• Ctrl + D: Exit the current shell or end input (used when there is no text on the command line).
• Ctrl + R: Search command history interactively.

1. Command history:

• Up Arrow or Ctrl + P: Move to the previous command in history.
• Down Arrow or Ctrl + N: Move to the next command in history.
• Ctrl + R: Search command history interactively.
• Ctrl + G: Escape from the history search mode without executing a command.

1. Tab completion:

• Tab: Auto-complete a command, file, or directory name. Pressing Tab twice shows available options if there are multiple matches.

1. Miscellaneous:

• Ctrl + Z: Suspend the current foreground process (can be resumed with the fg command).
• Ctrl + S: Stop the terminal output (can be resumed with Ctrl + Q).
• Ctrl + Q: Resume terminal output (after it has been stopped with Ctrl + S).
• Ctrl + \\: Send the QUIT signal to the current process (similar to pressing Ctrl + C, but more forceful).
• Ctrl + H or Backspace: Delete the character before the cursor.

These are just a few of the many shortcuts available in Bash. You can find more shortcuts and customize them by modifying your Bash configuration file (~/.bashrc or ~/.bash_profile).
