One of the things that I have always loved about Unix and then Linux is how it allows me to connect a series of commands together with pipes and get a lot of work done without a lot of effort. I can generate the output that I need in the form that I need it. It’s not just the existence of the pipes themselves, but the flexibility of the Linux commands. You can run commands, select portions of the output, sort the results or match on specific strings and you can pare the results down to just what you want to see.
In this post, we’re going to look at a couple commands that demonstrate the power of the pipe and how easily you can get commands to work together.
