golang使用os/exec庫(kù)查詢進(jìn)程方式

更新時(shí)間：2026年04月27日 09:09:25 作者：alden_ygq

本文介紹了使用Go語(yǔ)言os/exec查詢進(jìn)程的方法,并提供了兩種方式,第一種方式輸出了當(dāng)前系統(tǒng)所有運(yùn)行的進(jìn)程,第二種方式可以過(guò)濾出指定進(jìn)程的信息

golang使用os/exec庫(kù)查詢進(jìn)程

本文主要介紹如何使用os/exec庫(kù)查詢進(jìn)程。

package main

import (

    "fmt"

    "os/exec"

)

func main() {

    cmd := exec.Command("ps", "-ef")

    output, err := cmd.Output()

    if err != nil {

        fmt.Println(err)

        return

    }

    fmt.Println(string(output))

}

輸出：

上述代碼邏輯會(huì)獲取到當(dāng)前系統(tǒng)中所有運(yùn)行的進(jìn)程，但如果只需要獲取制定進(jìn)程信息呢，就需要針對(duì)進(jìn)程進(jìn)行過(guò)濾。

第一種方式

package main



import (

    "fmt"

    "bytes"
    "os/exec"

)
func RunCmd(cmdstring string) (string, error) {
	var out bytes.Buffer
	var stderr bytes.Buffer
	cmd := exec.Command("/bin/sh", "-c", cmdstring)
	cmd.Stdout = &out
	cmd.Stderr = &stderr
	err := cmd.Run()
	if err != nil {
		fmt.Printf("err:%v\n",err)
		return fmt.Sprintf("%s",stderr.String()),err
	}
	return fmt.Sprintf("%v",out.String()),nil
}

func main() {
    cmd := fmt.Sprintf("ps -ef | grep '%v'| grep -v grep","/bin/zsh --login -i")
    result,err := RunCmd(cmd)
    if err != nil {
	fmt.Printf("run cmd:%v failed:%v\n",cmd,err)
	return
    }

    fmt.Println(result)

}

輸出：
