英文:
Executing ssh command with args using Golang os/exec leads to Exit status 127
问题
在我的golang程序中，我需要通过ssh在远程服务器上执行命令。
我的计算机有一个存储的私钥，可以无需密码连接到服务器。
这是我运行远程命令的代码：
out, err := exec.Command("ssh", "myserver.com", "'ls'").Output()
fmt.Println(string(out), err)
这段代码按预期工作，但是当我在ssh服务器上执行的命令中添加参数时，我会收到一个带有Exit Status 127的错误。
示例代码：
out, err := exec.Command("ssh", "myserver.com", "'ls .'").Output()
fmt.Println(string(out), err, exercise)
这段代码导致出现exit status 127的错误。
为了避免这个问题，我应该如何格式化我的ssh命令？
英文:
In my golang program, I need to execute a command on a remote server via ssh.
My computer has a private key stored to connect to the server without password.
Here's my code for running remote commands:
out, err := exec.Command("ssh", "myserver.com", "'ls'").Output()
fmt.Println(string(out), err)
This code works as expected, however, when I add arguments to the command executed on the ssh server, the I get an error with Exit Status 127
Example Code:
out, err := exec.Command("ssh", "myserver.com", "'ls .'").Output()
fmt.Println(string(out), err, exercise)
This code leads to: exit status 127
How do I have to format my ssh command in order to avoid this?

“.”是你的命令中的另一个参数，必须单独在参数列表中传递：
out, err := exec.Command("ssh", "myserver.com", "ls", ".").Output()
或者：
out, err := exec.Command("ssh", "myserver.com", "ls", "/path/to/any/other/dir").Output()
英文:
. is another argument in your command which has to be passed in the argument list separately:
out, err := exec.Command("ssh", "myserver.com", "ls", ".").Output()
or:
out, err := exec.Command("ssh", "myserver.com", "ls", "/path/to/any/other/dir").Output()
