Linux pipeline operator and linux Pipeline

Who can give me an example of how to use the channel operators in linux?

As long as you understand what a pipeline is, it's easy.
The pipeline "|" refers to the command input after the Pipeline Using the preceding command output.
For example:
Ls-a | grep test | awk "{print $1 }"
The result of ls-a is to include test in the handsome selection, and then print the first column.

What is the symbol of the pipeline command in linux?
