Examples of usage

Basic params -u, -c, -i:

$ ssh-run [params] -i ~/.ssh/id_rsa -u admin -c "uptime" host1 host2:4566 root@host3 john@host4:3434 ...

this will execute uptime command on hosts:

• host1: connect to default ssh port - 22, use username - admin
• host2: connect to custom ssh port - 4566, use username - admin
• host3: connect to default ssh port - 22, use username - root
• host4: connect to custom ssh port - 3434, use username - john

Specify username as part of host string:

$ ssh-run -i ~/.ssh/aws-ec.pem -c "uname -r" [email protected]

10.10.10.14:22 ❭❭❭ uname -r (time: 1s)
6.1.0-30-cloud-amd64

the same as:

$ ssh-run -i ~/.ssh/aws-ec.pem -c "uname -r" -u admin 10.10.10.14

10.10.10.14:22 ❭❭❭ uname -r (time: 1s)
6.1.0-30-cloud-amd64

Multiple hosts:

$ ssh-run -i ~/.ssh/aws-ec.pem -c "uname -r" -u admin 10.10.10.14 10.10.10.12 10.10.10.24
