Random Integer in Linux. shuf Generates a Number in an Interval.

The easiest way to do this is to use shuf. You can generate a single integer between n and m with:

shuf -i{{n}}-{{m}} -n 1

where you replace {{n}} and {{m}} with the appropriate integers.

On macOS, where shuf is not installed by default, just use python:

python3 -c"import random;print(random.randint({{n}}, {{m}}))"
