Write a complete bash script that takes a filename as input using the read command. The script first checks if the file exists. If the file exists then continue with rest of the script. If the file does not exist output that it doesn’t exist and end the script. If the file exists then check if the file is executable. If the file is executable, output a message indicating it is executable else if the file is not executable then make the file executable using the chmod command and output a message indicating that the file is now executable. Also run a ls -l on the file to verify to the user that the file has been made executable. Use If statements and test file operators.
