在go中封裝一個bash函數，用於執行bash指令

package mainimport "os/exec"// 执行bash命令，返回输出以及执行后退出状态码func Bash(cmd string) (out string, exitcode int) {
    cmdobj := exec.Command("bash", "-c", cmd)
    output, err := cmdobj.CombinedOutput()
    if err != nil {
        // Get the exitcode of the output
        if ins, ok := err.(*exec.ExitError); ok {
            out = string(output)
            exitcode = ins.ExitCode()
            return out, exitcode        }
    }
    return string(output), 0}

執行

    out, _ := utils.Bash("ifconfig")
    fmt.Println(out)}// 输出:lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
