false – The Return Status is Failure

The false command is a built-in Linux command that is used to return a non-zero (failure) status code. It does not perform any action or output any message, but it is useful in shell scripts where a non-zero status code is required.

Overview

The false command is used to return a non-zero (failure) status code. It is often used in shell scripts where a non-zero status code is required. For example, if a script needs to exit with a failure status code, the false command can be used to accomplish this.

#!/bin/bash
# This script will exit with a failure status code
false

Options

The false command does not have any options.

Troubleshooting Tips

The false command is a very simple command and is unlikely to cause any issues. However, if you are using the false command in a script and it is not returning the expected status code, you should check the script for errors.

Notes

• The false command is often used in combination with the true command, which returns a zero (success) status code.
• The false command is a built-in command and is available on all Linux systems.
