# Procs
A simple interface to running child processes in [Ponylang](https://ponylang.io):
```pony
use "procs"
actor Main
new create(env: Env) =>
try
let result_promise = Procs.run_env(env, ["/usr/bin/echo"; "how"; "awesome"; "is"; "this;"])?
result_promise.next[None]({(res) =>
match res
| let pres: ProcessResult =>
env.out.write(pres.stdout)
| let perr: ProcessError =>
env.err.print("Meh! :(")
end
})
end
```
No need to create a [ProcessNotify](process-ProcessNotify.md) or a [ProcessMonitor](process-ProcessMonitor.md) and
accumulate chunks received from stdout, while all you want is to get stdout as `String`. Just run your process and
handle the [Promise](promises-Promise.md) containing either the [ProcessResult](procs-ProcessResult.md) with `exit_code`,
`stdout` and `stderr` or an instance of [ProcessError](process-ProcessError.md).
It is possible to pass environment variables and write something to stdin of the child process.
