ssh-agent子进程中的几个命令

Question

我想临时给 ssh-agent 添加一个自定义键，执行一些命令然后忘记它。

手册页说明如下：

ssh-agent [-c | -s] [-d] [-a bind_address] [-t life] [command [arg ...]]
If a commandline is given, this is executed as a subprocess of the agent. When the command dies, so does the agent.

测试表明它确实适用于一个命令：

# ssh-agent ssh-add user_rsa_key
Identity added: user_rsa_key (user_rsa_key)

但不是多个命令：

# ssh-agent { ssh-add user_rsa_key; ssh-add -l; }
-bash: syntax error near unexpected token `}'
# ssh-agent $(ssh-add user_rsa_key; ssh-add -l)
Could not open a connection to your authentication agent.

SSH_AUTH_SOCK=/tmp/ssh-UQYDpH5Mopk3/agent.25436; export SSH_AUTH_SOCK;
SSH_AGENT_PID=25437; export SSH_AGENT_PID;
echo Agent pid 25437;

有办法吗？

Answer 1

将两个（或更多）命令包装在一个 bash 命令中，如下所示：

 ssh-agent bash -c "ssh-add user_rsa_key; ssh-add -l"

（或者可能将它们放在脚本中）。
