# tentarun

Run commands on multiple machines.

## Examples

Run a command on multiple hosts.

With a username and password:

    tentarun -u username -p password -h host1,host2,host3 "tail /var/log/nginx/access.log"

    tentarun -p password -h host1,host2,host3 "tail /var/log/nginx/access.log"

With a username and keyfile

    tentarun -u username -k keyfile -h host1,host2,host3 "tail /var/log/nginx/access.log"

    tentarun -k keyfile -h host1,host2,host3 "tail /var/log/nginx/access.log"

Pass environment variables

    tentarun -e "FOO=bar BAR=foo" -h host1,host2,host3 "echo $FOO"

If you want to return the server name with the output pass -v.

If you want to return json output of the following format specify the -j flag:

```

    [

      {

        "hostname": "host1",

        "output": "output1"

      }

    ]

```

## Uses

 - Combine outputs of multiple machines and and parse it using

   local tools.
