Implement the <code>cd</code> command by calling <a href="https://pkg.go.dev/os#Chdir" rel="nofollow noreferrer">os.Chdir</a>.
Because a subprocess cannot change the working directory of a parent process, there is not a separate executable for the <code>cd</code> command. The <code>cd</code> command is builtin to command line interpreters.

<a href="https://pkg.go.dev/os/exec" rel="nofollow noreferrer">os/exec</a> package helps you execute terminal commands in Go.
Executing system commands is quite simple. Cmd holds your external command.
So in linux suppose you want to run &quot;echo hello&quot; command, you'd write the following code.
<pre><code>cmdStruct := exec.Command(&quot;echo&quot;,&quot;hello&quot;) 
out,err := cmdStruct.Output()
if err != nil {
 fmt.Println(err)
}
fmt.Println(string(out))
</code></pre>
This is one of the most basic way. However, in Windows, you need to pass &quot;echo hello&quot; as an argument to Command prompt or Powershell.
<pre><code> cmdStruct:= exec.Command(&quot;cmd.exe&quot;,&quot;/c&quot;,&quot;echo&quot;,&quot;hello&quot;)
</code></pre>
To simplify this pass arguments in a single slice,
<pre><code>args:= strings.Split(&quot;/c echo hello there how are you&quot;,&quot; &quot;)
cmdStruct:= exec.Command(&quot;cmd.exe&quot;,args...)
</code></pre>
Check out <a href="https://stackoverflow.com/a/71639965/15866278">this answer</a> for a better understanding and an enhanced version of this code.
For cd you can use <a href="https://pkg.go.dev/os#Chdir" rel="nofollow noreferrer">os.Chdir()</a> and <a href="https://pkg.go.dev/os#Getwd" rel="nofollow noreferrer">os.Getwd()</a> to change and view your working directory respectively. But if you require your command to execute in a specific directory tou can set <code>Dir</code> of your command i.e.
<pre><code>cmdStruct.Dir = &quot;path/to/directory&quot;
</code></pre>
or
<pre><code>cmdStruct.Dir = filepath.Join(&quot;path&quot;,&quot;to&quot;,&quot;directory&quot;)
</code></pre>

blocks|key|1476384|text|尽管我已经很久没有问这个问题了，我还是觉得回答这个问题会很好。简单地说，是不可能的。程序基本上是在它们自己的小盒子上运行的，这意味着虽然os.Chdir()在技术上确实改变了工作目录，但之后它会“恢复”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1476385|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Even though it's been quite a while since I asked this, I figured it would be good to answer this. To put it simply, there's no way. Programs essentially run on their own little contained box, which means while os.Chdir() does technically change the working directory, it &quot;reverts back&quot; afterwards.

I'm creating a CLI tool in Golang, and I'm new to both Golang and making tools for the terminal. I need to execute terminal commands right from my program (specifically <code>cd</code>). How do I do this? I followed along with <a href="https://stackoverflow.com/questions/6182369/exec-a-shell-command-in-go">this</a> post, but it threw an error saying that echo wasn't found in %path%
Thanks in advance for any help!

How do you execute terminal commands from Golang?

我在Golang中创建了一个CLI工具，我对Golang和为终端制作工具都很陌生。我需要从我的程序(特别是cd)执行终端命令。我该怎么做？我跟踪了 post，但是它抛出了一个错误，它说在%path%中找不到回声提前感谢您的帮助！
