This feels like it should already be a feature in a terminal. But I didn’t find anything that let me do this efficiently.

I had a rust library for converting list like 1-4,8-10 into vectors, but thought I’d expand it into a command line command as well, as it is really useful when I want to run batch commands in parallel using templates.

I wanted to share it since it might be a useful simple command for many people.

    Yes, just give the step as the third number: {1..10..2}

      {1…10…2}

      Wow, that’s nice to know. I guess my program will at least make it easier since you can type it in a more humane way, but not essential.

        There’s also seq:

        $ seq 1 2 10
        

        This will print the numbers starting from 1, incrementing by 2 until you get to 10.

          Seq will only print one sequence, though. The program’s focus is discontinuous range. Something like: 1:2:10,20:2:30
