The bind command is used to display or set keyboard keys and their associated functions in Linux. It is a built-in command that is available in most Linux distributions. The bind command allows users to customize their keyboard shortcuts and create new key bindings for various commands.
Overview
The bind command can be used to display the current key bindings for the terminal or shell. To display the current key bindings, simply type bind in the terminal and press enter. This will display a list of all the current key bindings for the terminal or shell.
To set a new key binding, use the following syntax: bind key-sequence function. For example, to bind the Ctrl+Alt+T key combination to launch the terminal, use the following command: bind -x '"\C-\A-t": gnome-terminal'. This will bind the Ctrl+Alt+T key combination to launch the GNOME terminal.
The bind command can also be used to create aliases for frequently used commands. For example, to create an alias for the ls command, use the following command: bind -x '"\C-l": ls'. This will create an alias for the ls command, and pressing Ctrl+L in the terminal will execute the ls command.
Options
The bind command has several options that can be used to customize its behavior. The following table lists all available options for the bind command:
| Option | Description |
|---|---|
-f |
Read key bindings from a specified file |
-l |
List all key bindings |
-m |

-p |
Display key bindings in a format that can be used in inputrc files |
-q |
Quiet mode: do not display any output |
-r |
Remove a key binding |
-s |
Display key bindings in a format that can be used in shell scripts |
-u |

Troubleshooting tips
If you are having trouble setting a key binding with the bind command, make sure that you are using the correct syntax. The syntax for setting a key binding is bind key-sequence function. The key sequence should be enclosed in double quotes, and the function should be a valid command or alias.
If you are still having trouble, try using the -m option to display the key bindings in a more human-readable format. This can help you identify any errors in your key binding syntax.
Notes
- The
bindcommand can be used to customize key bindings for the terminal or shell, but it does not affect key bindings for individual applications. - The
bindcommand can be used to create aliases for frequently used commands, but it is recommended to use thealiascommand instead for this purpose.
