For the 'Alternatives' section, there's also gnu parallel which I have been fairly happy with. https://www.gnu.org/software/parallel/man.html#DIFFERENCES-BETWE

  I will add, thanks. But it uses binary SSH, it's not efficient. Can you give me an example of such invokation? Layman's `parallel -S host1,host2 hosname` didn't work.

    I am not quite sure what "it uses binary SSH" is meant to say. It sounds as if you were refering to the SSH protocol (which of course is "binary"), though my guess is that you mean to say that it relies on executing a separate "ssh binary" (note in particular "ssh" vs. "SSH"). If the latter interpretation is right, perhaps rephrase what you wrote in your README?

    parallel --nonall -S hosta,hostb --tag 'echo this is run on; hostname'
    • seletskiy 10y ago
      Change `echo this in ...` to `tail -f /var/log/mail.log` and parallel will show no output. orgalorg will output exactly what you expect.

        Use --line-buffer to get line buffered output.
        • seletskiy 10y ago
          And it will never get past first server's output, because command is never finished.

            Ahh, but Sir, I think thou did not test it. Otherwise thou would have written differently.

  pssh (parallel SSH) is also very nice: http://linux.die.net/man/1/pssh http://linux.die.net/man/1/pssh.
