Chaining commands using operators

The more we use command-line tools, the more we start stringing complex commands together. Sometimes it's for convenience, but other times, the output of one command can be used as input to another. Let's get some hands on practice with this by filling in the correct chain operators for the circumstances described in the instructions below.
