Recap - Log Builder

Build a simple activity log from scratch using multiple redirection techniques. Run these commands in order:

1. Use echo with > to write Session started to a new file called activity.log
2. Use echo with >> to append User logged in to activity.log
3. Use echo with >> to append Task completed to activity.log
4. Try to list a folder called invalid_path and redirect the error to activity.log using 2>>
5. Use cat to display the final contents of activity.log
