Compare two text files by key columns
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.
