How to check if dir exists over ssh and return results to host machine

bashshellssh

提问by hax0r_n_code

I'm trying to establish an SSH connection and see if a directory exist, and if that directory exists I want to run commands on the local machine that made the SSH call.

我正在尝试建立 SSH 连接并查看目录是否存在,如果该目录存在,我想在进行 SSH 调用的本地计算机上运行命令。

这是我尝试过的:

if [ ssh -t username@ssh_server -d /directory ]
then
{
    commands....
}
fi

Is something like this possible?

这样的事情可能吗?
