You're missing the important part in that example:
let outp =
Run
The way you're doing it is correct, but `execProcess` returns a `TaintedString`
([doc](https://nim-lang.org/docs/osproc.html#execProcess%2Cstring%2Cstring%2CopenArray%5Bstring%5D%2CStringTableRef%2Cset%5BProcessOption%5D)),
so you'd have to capture it or explicitly discard the result with `discard`
like this:
# default options contains poEvalCommand, which will ignore args, so we
specify our own set
discard execProcess("pkill", args=[" -9", process], options =
{poStdErrToStdOut, poUsePath})
Run
Unlike most languages, Nim does not allow you to drop a function return value
implicitly.
