Question

if a user enters a command and wishes to terminate it before its execution, what key presses can be used? (choose all that apply)

Answer 1

To terminate a command before execution in the command line, the key combinations Ctrl + C, Ctrl + Z, or Ctrl + \ can be used to interrupt or stop the process.

Step-by-step explanation:

When a user enters a command in the command line and wishes to terminate it before its execution, there are key presses they can use. The most common ones are:

• Ctrl + C: This is a universal key combination used to terminate a command or process in most operating systems, including Windows, Linux, and macOS.
• Ctrl + Z: This key combination is often used to suspend a foreground process, sending it to the background. However, in some situations, it can also effectively stop the execution of a command.
• Ctrl + \: This is a lesser-known combination that can be used in Unix-like operating systems to force quit a process.

These key combinations can be immensely useful in managing commands and processes that users wish not to execute. Understanding how to capitalize, change to lowercase, insert punctuation, and control cursor movement is beneficial when dealing with the command line.
