About golang encapsulating a bash function for executing bash commands

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}

func main() { out, _ := utils.Bash("ifconfig") fmt.Println(out)}// 输出:lo0: flags=8049 mtu 16384 options=1203 inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 nd6 options=201gif0: flags=8010 mtu 1280stf0: flags=0<> mtu 1280en5: flags=8863 mtu 1500 ether ac:de:48:00:11:22 inet6 fe80::aede:48ff:fe00:1122%en5 prefixlen 64 scopeid 0x4 nd6 options=201 media: autoselect (100baseTX ) status: active ap1: flags=8802 mtu 1500 options=400 ether b2:9c:4a:b7:0f:e6 media: autoselect status: inactive en0: flags=8863 mtu 1500 options=400 ether 90:9c:4a:b7:0f:e6 nd6 options=201 media: autoselect () status: inactive awdl0: flags=8902 mtu 1500 options=400 ether fa:96:0c:c0:b4:98 nd6 options=201 media: autoselect status: inactive llw0: flags=8863 mtu 1500 options=400 ether fa:96:0c:c0:b4:98 nd6 options=201 media: autoselect status: inactive en1: flags=8963 mtu 1500 options=460 ether ee:48:05:91:d0:44 media: autoselect  status: inactive en2: flags=8963 mtu 1500 options=460 ether ee:48:05:91:d0:45 media: autoselect  status: inactive en3: flags=8963 mtu 1500 options=460 ether ee:48:05:91:d0:41 media: autoselect  status: inactive en4: flags=8963 mtu 1500 options=460 ether ee:48:05:91:d0:40 media: autoselect  status: inactive bridge0: flags=8863 mtu 1500 options=63 ether ee:48:05:91:d0:44 Configuration: id 0:0:0:0:0:0 priority 0 hellotime 0 fwddelay 0 maxage 0 holdcnt 0 proto stp maxaddr 100 timeout 1200 root id 0:0:0:0:0:0 priority 0 ifcost 0 port 0 ipfilter disabled flags 0x0 member: en1 flags=3 ifmaxaddr 0 port 9 priority 0 path cost 0 member: en2 flags=3 ifmaxaddr 0 port 10 priority 0 path cost 0 member: en3 flags=3 ifmaxaddr 0 port 11 priority 0 path cost 0 member: en4 flags=3 ifmaxaddr 0 port 12 priority 0 path cost 0 nd6 options=201 media:  status: inactive utun0: flags=8051 mtu 1380 inet6 fe80::e60f:e004:7bd3:9732%utun0 prefixlen 64 scopeid 0xf nd6 options=201utun1: flags=8051 mtu 2000 inet6 fe80::62dc:7f46:6f6:b955%utun1 prefixlen 64 scopeid 0x10 nd6 options=201en7: flags=8863 mtu 1500 options=6467 ether 00:e0:4c:68:01:ea inet6 fe80::845:989:8b95:88e6%en7 prefixlen 64 secured scopeid 0xd inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255 nd6 options=201 media: autoselect (100baseTX ) status: active utun2: flags=8051 mtu 1500 inet 10.8.0.6 --> 10.8.0.5 netmask 0xffffffff
