Q&A How do you generate arbitrary random numbers from /dev/random?

Suppose I want to get random numbers from /dev/random with basic CLI tools. Is there a way to do it, that's easier to type and read than python -c 'import random; print(100 + 200*random.random())'?...

  • I know how to [generate random strings](https://linux.codidact.com/posts/291134) and I could generate a string of digits. But that's not very precise - what if I want numbers from `[134, 876874]`, for example?
