you can try use github.com/go-cmd/cmd module.
because golang can not use syscall by default.

example:

import (
    "fmt"
    "time"
    "github.com/go-cmd/cmd"
)

func main() {
    // Start a long-running process, capture stdout and stderr
    findCmd := cmd.NewCmd("find", "/", "--name", "needle")
    statusChan := findCmd.Start() // non-blocking

    ticker := time.NewTicker(2 * time.Second)

    // Print last line of stdout every 2s
    go func() {
        for range ticker.C {
            status := findCmd.Status()
            n := len(status.Stdout)
            fmt.Println(status.Stdout[n-1])
        }
    }()

    // Stop command after 1 hour
    go func() {
        <-time.After(1 * time.Hour)
        findCmd.Stop()
    }()

    // Check if command is done
    select {
    case finalStatus := <-statusChan:
        // done
    default:
        // no, still running
    }

    // Block waiting for command to exit, be stopped, or be killed
    finalStatus := <-statusChan
}
