关于golang封装一个bash函数，用于执行bash命令

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}

执行

func main() {    out, _ := utils.Bash("ifconfig")    fmt.Println(out)}// 输出:lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384        options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>        inet 127.0.0.1 netmask 0xff000000         inet6 ::1 prefixlen 128         inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1         nd6 options=201<PERFORMNUD,DAD>gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280stf0: flags=0<> mtu 1280en5: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500        ether ac:de:48:00:11:22         inet6 fe80::aede:48ff:fe00:1122%en5 prefixlen 64 scopeid 0x4         nd6 options=201<PERFORMNUD,DAD>        media: autoselect (100baseTX <full-duplex>)        status: activeap1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500        options=400<CHANNEL_IO>        ether b2:9c:4a:b7:0f:e6         media: autoselect        status: inactiveen0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500        options=400<CHANNEL_IO>        ether 90:9c:4a:b7:0f:e6         nd6 options=201<PERFORMNUD,DAD>        media: autoselect (<unknown type>)        status: inactiveawdl0: flags=8902<BROADCAST,PROMISC,SIMPLEX,MULTICAST> mtu 1500        options=400<CHANNEL_IO>        ether fa:96:0c:c0:b4:98         nd6 options=201<PERFORMNUD,DAD>        media: autoselect        status: inactivellw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500        options=400<CHANNEL_IO>        ether fa:96:0c:c0:b4:98         nd6 options=201<PERFORMNUD,DAD>        media: autoselect        status: inactiveen1: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500        options=460<TSO4,TSO6,CHANNEL_IO>        ether ee:48:05:91:d0:44         media: autoselect <full-duplex>        status: inactiveen2: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500        options=460<TSO4,TSO6,CHANNEL_IO>        ether ee:48:05:91:d0:45         media: autoselect <full-duplex>        status: inactiveen3: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500        options=460<TSO4,TSO6,CHANNEL_IO>        ether ee:48:05:91:d0:41         media: autoselect <full-duplex>        status: inactiveen4: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500        options=460<TSO4,TSO6,CHANNEL_IO>        ether ee:48:05:91:d0:40         media: autoselect <full-duplex>        status: inactivebridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500        options=63<RXCSUM,TXCSUM,TSO4,TSO6>        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<LEARNING,DISCOVER>                ifmaxaddr 0 port 9 priority 0 path cost 0        member: en2 flags=3<LEARNING,DISCOVER>                ifmaxaddr 0 port 10 priority 0 path cost 0        member: en3 flags=3<LEARNING,DISCOVER>                ifmaxaddr 0 port 11 priority 0 path cost 0        member: en4 flags=3<LEARNING,DISCOVER>                ifmaxaddr 0 port 12 priority 0 path cost 0        nd6 options=201<PERFORMNUD,DAD>        media: <unknown type>        status: inactiveutun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1380        inet6 fe80::e60f:e004:7bd3:9732%utun0 prefixlen 64 scopeid 0xf         nd6 options=201<PERFORMNUD,DAD>utun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000        inet6 fe80::62dc:7f46:6f6:b955%utun1 prefixlen 64 scopeid 0x10         nd6 options=201<PERFORMNUD,DAD>en7: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500        options=6467<RXCSUM,TXCSUM,VLAN_MTU,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>        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<PERFORMNUD,DAD>        media: autoselect (100baseTX <full-duplex>)        status: activeutun2: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500        inet 10.8.0.6 --> 10.8.0.5 netmask 0xffffffff
