ssh-copy-id

ssh-copy-id是一个用于将本地公钥复制到远程主机的命令。它可以将本机的公钥复制到远程机器的authorized_keys文件中，并设置合适的权限。\[1\]\[2\]\[3\]使用ssh-copy-id命令时，可以通过-i选项指定认证文件(公钥)，也可以使用默认的~/.ssh/identity.pub作为默认公钥。\[2\]\[3\]在运行ssh-copy-id命令时，如果多次运行，它不会检查重复，会在远程主机中多次写入authorized_keys文件。\[3\]使用示例可以是：ssh-copy-id -i ~/.ssh/id_rsa.pub remote-host，其中remote-host是远程主机的地址。\[4\]需要注意的是，ssh-copy-id将公钥写入远程机器的~/.ssh/authorized_keys文件中。\[4\]如果在使用选项-i时没有传入值，或者~/.ssh/identity.pub文件不可访问（不存在），ssh-copy-id会显示错误信息。\[5\]
