Class type

Extension to Stdlib.Sys that can also execute on remote runners.

Most functions from this module just call their Stdlib.Sys equivalent when runner is not specified. When runner is specified, they instead use SSH to execute a shell command remotely with a similar effect.

type error

Errors that can occur when executing a Sys command on a remote runner.

exception Remote_error of error

Exception raised when failing to execute a Sys command remotely.

This is not raised when running a command without a runner. Instead, Sys_error is raised.
