How to pipe several commands in Go?

by

For simple scenarios, you could use this approach:

bash -c "echo 'your command goes here'"

For example, this function retrieves the CPU model name using piped commands:

func getCPUmodel() string {
        cmd := "cat /proc/cpuinfo | egrep '^model name' | uniq | awk '{print substr($0, index($0,$4))}'"
        out, err := exec.Command("bash","-c",cmd).Output()
        if err != nil {
                return fmt.Sprintf("Failed to execute command: %s", cmd)
        }
        return string(out)
}
