执行系统命令

执行命令不获取结果

直接调用run()

package main
import (
    "fmt"
    "os/exec"
)
func main() {
    //新建文件1.txt
    cmd := exec.Command("cmd", "/C", "echo", "111111", ">", "1.txt").Run()
    fmt.Println(cmd)
}

package main
import (
    "fmt"
    "os/exec"
)
func main() {
    cmd, _ := exec.Command("cmd", "/C", "echo", "123", ">", "123.txt").CombinedOutput()
    fmt.Println(string(cmd))
}

如果是Linux就简单了，不用cmd /C。

执行命令并获取结果

使用CombinedOutput函数。

package main
import (
    "fmt"
    "os/exec"
)
func main() {
    //新建文件1.txt
    cmd, _ := exec.Command("cmd", "/C", "echo", "222222").CombinedOutput()
    fmt.Println(string(cmd))
}
