title: Exec
|
|

|
|
|
|
The `exec` subcommand can do some things that the configuration file can't do yet. The command `exec host` can execute commands on many hosts.
|
|
|
|
`exec host` takes the following arguments:
|
|
|
|
```sh
|
|
-c, --commands strings Accepts space-separated names of commands.
|
|
-h, --help help for host
|
|
-m, --hosts strings Accepts space-separated names of hosts.
|
|
```
|
|
|
|
The commands have to be defined in the config file. The hosts need to at least be in the ssh_config(5) file.
|
|
|
|
```sh
|
|
backy exec host [--commands=command1 -commands=command2 ... | -c command1 -c command2 ...] [--hosts=host1 --hosts=hosts2 ... | -m host1 -m host2 ...] [flags]
|
|
```
