Key Features of AWK

AWK

General purpose

AWK is a venerable, powerful, elegant, and simple tool that everyone should know.

Easy

Extracting a column from your CSV is as simple as "awk -F, '{print $1}' file"

Powerful

Replace complex grep|sed|tr|cut pipelines with a short AWK script.

Do more with less

Simple and flexible data structures, user-defined functions; AWK can do more than you think.

One-liners

With just a few dozen characters, you can achieve impressive text transformations.

Widely used

Besides /bin/sh, AWK is the only other scripting language in the standard Unix environment.

Get mentored the AWK way

Every language has its own way of doing things. AWK is no different. Our mentors will help you learn to think like a AWK developer and how to write idiomatic code in AWK. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in AWK - they'll help you discover the things you don't know that you don't know.
