下面由golang教程栏目给大家介绍关于golang封装一个bash函数，用于执行bash命令析，希望对需要的朋友有所帮助！
在go中封装一个bash函数，用于执行bash命令
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}登录后复制
执行
func main() {
out, _ := utils.Bash("ifconfig")
fmt.Println(out)}// 输出:lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
