英文:
Running Linux commands with multiple arguments
问题
在进行一些调查后，我可以像这样从Go中运行Linux命令：
func main() {
lsCmd := exec.Command("ls")
lsOut, err := lsCmd.Output()
if err != nil {
panic(err)
}
fmt.Println(">ls")
fmt.Println(string(lsOut))
}
我想要做的是在远程机器上运行以下命令：
ssh -p $someport $someuser@$someip 'ls'
我可以在终端中成功执行此命令，但是当我尝试在Go中运行时，我会得到以下错误：
panic: exec: "ssh -p $someport $someuser@$someip 'ls'": 可执行文件在$PATH中未找到
更新：为了方便起见，我更新了问题。
英文:
After some digging I can run Linux commands from go like this:
func main() {
lsCmd := exec.Command("ls")
lsOut, err := lsCmd.Output()
if err != nil {
panic(err)
}
fmt.Println(">ls")
fmt.Println(string(lsOut))
}
What I want to do is, running following command in remote machine:
ssh -p $someport $someuser@$someip 'ls'
I can do this successfully from my terminal, but when I try to run it within Go, I get following error:
panic: exec: "ssh -p $someport $someuser@$someip 'ls'": executable file not found in $PATH
Update: I updated the question for convenience.

根据关于exec包的文档，程序名称和参数是Command方法的不同参数。
你应该这样做：
exec.Command("ssh", "-p port", "user@ip", "'ls'")
如果你需要更复杂的操作，你也可以查看go.crypto/ssh包。
英文:
As per the doc about the exec package, program name and arguments are differents parameters of the Command method.
You should do something like that :
exec.Command("ssh", "-p port", "user@ip", "'ls'")
If you need something more elaborate, you could also look at the go.crypto/ssh package.

如果你想在远程机器上运行多个命令，下面的技巧可能会帮助你实现这个目标。
ssh username@ip < EOf
ls -I
pwd
uname
Eof
请注意，它不会传递任何特殊字符，如. ,等。
英文:
If you want run multiple commands on a remote machine the below trick might help you achieve this.
Ssh username@ip < EOf
ls -I
Pwd
Uname
Eof
Please note that it doesn't pass any special characters like . , etc.
