Functions

func Execute

func Execute(c []string, terminate <-chan struct{}) ([]byte, error)

Execute is a concurrent wrapper around Go's os/exec Output() method. It runs a command, and returns its standard output as a byte slice. If a long-running command is being executed, it can easily be killed at any time using the terminate channel as the process is spawned in a Goroutine.
