This is a small utility to loop a command, in a shell. This is deceptively simple, you can loop a command forever, or loop until it is succeeded or failed.

Currently, it really does nothing else than a bash `for` and `sleep`, but I intend to add the possibility of running a command in loop, in parallel.

In conjonction with some tests/stress tools (like https://hurl.dev who I am one of the maintainer), I think this can be useful to other...

  $ loop --iter 4 --delay 1000 date
