英文:
A program that takes a command as input and runs it in the terminal
问题
我有点知道如何在C语言中实现这个，但在Go语言中如何实现呢？
以下是我使用的代码：
package mainimport ("fmt""os""os/exec""strings")func main() {if len(os.Args) < 2 { // 没有指定命令fmt.Println("Usage: ./program_name terminal_command ...")os.Exit(1)} else {cmd := strings.Join(os.Args[1:], " ")cmdParts := strings.Split(cmd, " ")cmdName := cmdParts[0]cmdArgs := cmdParts[1:]cmdExec := exec.Command(cmdName, cmdArgs...)cmdExec.Stdout = os.StdoutcmdExec.Stderr = os.Stderrerr := cmdExec.Run()if err != nil {fmt.Println(err)os.Exit(1)}}}
希望对你有帮助！

I kind of know how to do this in C, but how to do it in Go?
This is the code I'm using:
#include <stdio.h>#include <stdlib.h>#include <string.h>#define MAX_CMN_LEN 100int main(int argc, char *argv[]){char cmd[MAX_CMN_LEN] = "", **p;if (argc < 2) /*no command specified*/{fprintf(stderr, "Usage: ./program_name terminal_command ...");exit(EXIT_FAILURE);}else{strcat(cmd, argv[1]);for (p = &argv[2]; *p; p++){strcat(cmd, " ");strcat(cmd, *p);}system(cmd);}return 0;}

像这样：
package mainimport ("os""os/exec")func main() {if len(os.Args) < 2 {panic("用法：./程序名 终端命令 ...")}cmd := exec.Command(os.Args[1], os.Args[2:]...)cmd.Run()}
英文:
Something like this:
package mainimport ("os""os/exec")func main() {if len(os.Args) < 2 {panic("Usage: ./program_name terminal_command ...")}cmd := exec.Command(os.Args[1], os.Args[2:]...)cmd.Run()}
