What does char '|' mean in Linux command

Question

In example:

lsof -i -P -n | grep LISTEN

How do I "read" that command? I have tried to search anywhere, and found nothing explained those.

This PIPE operator is very useful where the output of the first command acts as an input to the second command. For example, pipeline the output of ls -l to ‘less‘ and see the output of the command.
