下面由golang教程欄目給大家介紹關(guān)于golang封裝一個bash函數(shù)，用于執(zhí)行bash命令析，希望對需要的朋友有所幫助！

在go中封裝一個bash函數(shù)，用于執(zhí)行bash命令

package mainimport "os/exec"// 執(zhí)行bash命令，返回輸出以及執(zhí)行后退出狀態(tài)碼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(zhí)行

func main() {     out, _ := utils.Bash("ifconfig")     fmt.Println(out)}// 輸出: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: active ap1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500         options=400<CHANNEL_IO>         ether b2:9c:4a:b7:0f:e6          media: autoselect         status: inactive en0: 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: inactive awdl0: 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: inactive llw0: 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: inactive en1: 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: inactive en2: 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: inactive en3: 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: inactive en4: 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: inactive bridge0: 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: inactive utun0: 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: active utun2: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500         inet 10.8.0.6 --> 10.8.0.5 netmask 0xffffffff
