Problem in running the command with '&' ("/opt/medusa_labs/test_tools/bin/maim -b256k -Q8 -f/dev/sdc &")

Hi,

I have a traffic tool for which i have written a module with the required options which i send to be triggered through Ansible for execution.

It goes this way:

“/opt/medusa_labs/test_tools/bin/maim -b256k -Q8 -f/dev/sdc &”

When executing on the host i get the following error: “(program startup error)\n\nERROR: INIT: ‘&’ is an unrecognized command line parameter\n"}”

Here ‘&’ is being taken as an option rather than telling it to run as a background. Manually running the same command on the host works fine.

The reason for going with this approach is that Async and Poll when used, log files do not get created by the traffic tool and when run without this its a kind of infinite command which runs for ever.

So can anyone please give some suggestions/ideas on the approach that can solve this?

If you are using the command module, this is because command doesn’t understand shell constructs such as &

You would need to use the shell module instead.

However, you are still likely to have issues with this. The command will still likely end before you expect. I’d really recommend creating a real service that can start and potentially monitor this command more appropriately.
