Bash Input/Output and Streams

Master Bash I/O by learning to redirect output, chain commands with pipelines, and provide input using heredocs, script arguments, read, and xargs.

What you'll learn

Just run the command, that's all I need to do! Suddenly, you're neck-deep in cryptic errors and broken scripts. We've all been there. In this course, Bash Input/Output and Streams, you’ll learn to confidently work with input and output in the shell. First, you’ll explore redirecting STDOUT and STDERR to files. Next, you’ll discover pipelines—how they pass data between commands using STDIN and STDOUT. Finally, you’ll learn all about STDIN and a myriad of ways to provide inputs. When you’re finished with this course, you’ll have a firm grasp on how Bash I/O streams work to reliably compose pipelines with predictable results!
