Is there a equvilant of Python's `os.system()` in Golang?

Time:11-15

I want to create a wrapper program that can wrapper whatever shell commands user provides, like:

./wrapper "cmd1 && cmd2"

In Python, I can call os.system("cmd1 && cmd2"). But Golang's exec.Command needs a list for command and args. Is there way in Golang to archive the same as Python's os.system()?

CodePudding user response:

os/exec https://pkg.go.dev/os/exec

package main

import (
    "fmt"
    "os/exec"
)

func main() {
    cmd := exec.Command("/usr/bin/bash", "-c", os.Args[1])
    output, err := cmd.CombinedOutput()
    if err != nil {
        panic(err)
    }
    fmt.Println(string(output))
}
$ go run main.go "ls -alh && pwd"
