Using the `false` Command (with examples)
Return a non-zero exit code
Code:
false
Motivation:
The false command is used to simply return a non-zero exit code. This can be useful in scripts or programs when you want to indicate that an error or failure has occurred.
Explanation:
The false command does not take any arguments. It simply returns a non-zero exit code indicating failure. In Unix-like systems, an exit code of 0 typically means success, while any non-zero value signifies failure.
Example Output:
$ false
$ echo $?
1
In the example above, running the false command returns a non-zero exit code of 1. This can be confirmed by running the echo $? command, which prints the exit code of the last executed command.
