That's because the interrupt signal is not caught.

This works:

  sh -c 'echo foo >"$1" && trap "exit 1" INT && sleep 20' test hoi || rm hoi

And so does this:

  #!/bin/sh

  ruby - hoi <<EOF || rm hoi
  File.write(ARGV[0], 'foo')
  begin
    sleep(10)
  rescue Exception
    exit(1)
  end
  EOF

Both asciidoc and asciidoctor trap the signal.

Yes, if we agree this approach is indeed desirable I can do that.

Cheers.
