Here is another simple example:

$ ls -s | sort -n

In this case, ls -s would normally print a listing of the current directory on the terminal, preceding each file with its size. But instead we've piped the output into sort -n, which sorts the output numerically. This is a really useful way to find large files in your home directory!

The following examples are more complex, but they demonstrate the power that can be harnessed using pipes. We're going to throw out some commands we haven't covered yet, but don't let that slow you down. Concentrate instead on understanding how pipes work so you can employ them in your daily Linux tasks.
