Suppose run_me.sh is a script file. Which command is used to make it executable?

This question is about making a script file, called "run_me.sh," executable. This means the computer can understand and run the instructions inside the script.

The command used to make a file executable is "chmod +x filename".

Let's break down the parts:
* chmod: This is the command used to change file permissions. * +x: This adds the "execute" permission to the file. * filename: This is the name of the file you want to make executable (in this case, "run_me.sh").

So the correct answer is Option D: chmod +x run_me.sh

The other options are incorrect.
* Option A (chmod +e), Option B (chmod +a), and Option C (chmod +y) are not valid commands for changing file permissions in Linux or macOS.
