Need Some Help on this for a bash script!

For this assignment, you will use sed, bash, and the other utilities you have used in class to create a program for use in an academic setting for which redacting sensitive information for extra-departmental communication is important. Your program should take the names of one or more files that are to be redacted as command line arguments. This assignment requires only sed, bash, and the other utilities used so far in class. Do not use awk, perl, Python, or any other languages/utilities. Hint: make use of the \w character class (equivalent to [a-zA-Z0-9_]). Hint: echo "My cat is very scattered." | sed -r 's/(^/\W) cat ($/\W)/\1dog\2/g'} My dog is very scattered.
