Copying ssh public key to server
问题
我正在尝试使用Go语言在本地$HOME/.ssh/目录下添加一个公钥。
我已经使用相同的代码运行多个命令而没有问题，但对于这个特定的命令却有问题。
identity := fmt.Sprintf("cat %s/.ssh/%s.pub", fileUtil.FindUserHomeDir(), p.sshkey.name)
address := fmt.Sprintf("| ssh %s@%s 'cat >> ~/.ssh/authorized_keys'", p.projectname.name, p.host.name)
cmd := exec.Command(identity, address)
err := cmd.Run()
if err != nil {
log.Fatal(err)
}
基本上，我想运行以下命令：
cat /home/foo/.ssh/foobar.pub | ssh foo@bar.com 'cat >> ~/.shh/authorized_keys'
如果我直接在命令行中运行它，是可以正常工作的。
我想在不同的OS X机器上运行这个程序，其中一些机器上没有安装ssh-copy-id。所以，我不考虑使用它。
但无论如何，我对其他建议也持开放态度。提前谢谢。
英文:
I'm trying to add a public key under my local $HOME/.ssh/ directory using Go.
I've been running multiple commands with this the same code without problem, but not for this particular one.
identity := fmt.Sprintf("cat %s/.ssh/%s.pub", fileUtil.FindUserHomeDir(), p.sshkey.name)
address := fmt.Sprintf("| ssh %s@%s 'cat >> ~/.ssh/authorized_keys', p.projectname.name, p.host.name)
cmd := exec.Command(identity, address)
err := cmd.Run()
if err != nil {
log.Fatal(err)
}
Basically I'm trying to run:
cat /home/foo/.ssh/foobar.pub | ssh foo@bar.com 'cat >> ~/.shh/authorized_keys'"
Which works fine if I run it through the command line directly.
I want to run this program in different OS X machines, where some don't have ssh-copy-id installed. So, I'm not considering to use it.
But anyway, I'm open to other suggestions. Thank you in advance.

你不需要在Go语言中执行/bin/sh -c "cat file"来读取文件。正常打开文件，并将其提供给ssh命令即可。
keyFile, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
cmd := exec.Command("ssh", "user@host", "cat >> ~/.ssh/authorized_keys")
cmd.Stdin = keyFile
// 以你想要的方式运行命令
out, err := cmd.CombinedOutput()
if err != nil {
fmt.Println(string(out))
log.Fatal(err)
}
以上是翻译好的内容，请确认是否满意。
英文:
You don't need to execute /bin/sh -c "cat file" to read a file in Go. Open the file normally, and give that to the ssh command
keyFile, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
cmd := exec.Command("ssh", "user@host", "cat >> ~/.ssh/authorized_keys")
cmd.Stdin = keyFile
// run the command however you want
out, err := cmd.CombinedOutput()
if err != nil {
fmt.Println(string(out))
log.Fatal(err)
}

你可以简单地使用rsync或scp来完成这个目的。

You could simply execute rsync or scp for this purpose.
