 # Shell
 The shell is a command-line interpreter that provides a user interface to an operating system's services. It allows users to interact with the system through text-based commands and scripts. Shell scripting refers to writing a series of commands in a script file to automate tasks and perform complex operations.

 Commands can be either a script, a binary or anything that can be executed. If you don't provide a full path to the file you want to run the shell will search in the locations defined in the `$PATH` environment variable.
 
+### Keyboard Shortcuts
+- `Ctrl + C`: Terminate the current running process or command.
+- `Ctrl + Z`: Suspend the current process and push it to the background.
+- `Ctrl + D`: Exit the terminal or send EOF (End Of File) if running a script or command.
+- `Ctrl + L`: Clear the terminal screen (similar to the clear command).
+- `Ctrl + A`: Move the cursor to the beginning of the line.
+- `Ctrl + E`: Move the cursor to the end of the line.
+- `Ctrl + U`: Delete everything from the cursor position to the beginning of the line.
+- `Ctrl + K`: Delete everything from the cursor position to the end of the line.
+- `Ctrl + W`: Delete the word before the cursor.
+- `Ctrl + R`: Search command history backward interactively.
+- `Ctrl + T`: Swap the current character with the previous one (transpose).
+- `Ctrl + Y`: Paste (yank) the last killed text.
+- `Ctrl + P`: Previous command in history (similar to the Up arrow key).
+- `Ctrl + N`: Next command in history (similar to the Down arrow key).
+- `Alt + F`: Move forward one word.
+- `Alt + B`: Move backward one word.
+- `Alt + D`: Delete the word after the cursor.
+- `Shift + PageUp/PageDown`: Scroll the terminal output up or down.
+- `Tab`: Auto-complete file or directory names.
+
+### Process Management
+- `Ctrl + Z`: Suspend a running process.
+- `fg`: Resume the last suspended process in the foreground.
+- `bg`: Resume the last suspended process in the background.
+- `jobs`: List all jobs currently running or suspended.
+
 ### Arguments
 Everything after the command will be provided to the command as arguments. Each argument is separated by a space character. To avoid that you could quote an argument or escape the space character.

 | **!**    | This is logical negation. This inverts a true condition into false and vice versa.                       | `[ ! false ]` is true.                  |
 | **-o**   | This is logical **OR**. If one of the operands is true, then the condition becomes true.                 | `[ $a -lt 20 -o $b -gt 100 ]` is true.  |
 | **-a**   | This is logical **AND**. If both the operands are true, then the condition becomes true otherwise false. | `[ $a -lt 20 -a $b -gt 100 ]` is false. |
