  1. This sounds like a VERY useful tool but I’m running Fedora Core 30 x86_64 and it’s not in the repository.

    What do I do? Are rpm’s available?

    • Your reply is awful and worthless. Why did you not state the alternative tools if you know some? Otherwise, your reply just makes you look snide and arrogant. Why not be polite?

  3. Really thanks for sharing this useful tool, I was looking for such tool since long time to record my Linux terminal courses and lessons in my university.

    thanks again.
