Compare two text files by key columns

# Getting Started

Let’s say we have two text files maintaining a list of systems with versions.

` $ cat a.txt MacOS 10.12 Windows 10 Ubuntu 16 `

` $ cat b.txt MacOS 10.14 Windows 10 Manjaro 17 `

To see which systems are new in b.txt, deleted in b.txt, and version changed in b.txt, run kvdiff -k1 a.txt b.txt in the terminal:

` $ kvdiff -k1 a.txt b.txt * MacOS 10.12 > MacOS 10.14 + Manjaro 17 - Ubuntu 16 `

KVDiff reports that MacOS has a version change, new system Manjaro with version 17 is added, and Ubuntu is deleted.
