go语言学习例子No.5–执行exe或shell命令

package main
import (
	"log"
	"os/exec"
)
func main() {
	cmd := exec.Command(`C:\Program Files (x86)\Google\Chrome\Application\chrome.exe`)
	err := cmd.Start()
	if err != nil {
		log.Fatal(err)
	}
}

go run后就可以马上打开谷歌浏览器了

shell命令

package main

import (
	"fmt"
	"os/exec"
)

func main() {
	cmd := exec.Command("bash", "-c", "whereis rclone")
	out, err := cmd.Output()
	if err != nil {
		fmt.Printf("error is: %s\n", out)
		return
	}
	fmt.Printf("%s\n", out)

}

这里把whereis rclone换成rclone config就会报错，为什么呢？因为rclone config后会要求输入，这样就会报错，可以直接忽略err就好了

执行windows的cmd命令

package main

import (
	"fmt"
	"os/exec"
)

func main() {
	cmd := exec.Command("cmd.exe", "/c", `E:\rclone\RcloneBrowser\rclone.exe config file`)
	out, err := cmd.Output()
	if err != nil {
		fmt.Printf("error is: %s\n", out)
		return
	}
	fmt.Printf("%s\n", out)
}
