Enter the following script named savefiles, and give yourself execute permission to the file:

$ cat savefiles #! /bin/bash echo "Saving files in working directory to the file savethem." exec > savethem for i in * do echo "===================================================" echo "File: $i" echo "===================================================" cat "$i" done a. Which error message do you receive when you execute this script? Rewrite the script so that the error does not occur, making sure the output still goes to savethem. b. What might be a problem with running this script twice in the same directory? Discuss a solution to this problem.
