使用ssh检查目录在远程计算机上是否存在 [英] Check if directory exists on remote machine with ssh

问题描述

这个问题已经发布，但是我想知道是否有一种方法可以直接从命令行(而不是从脚本)通过ssh BUT知道远程计算机上是否存在目录.正如我在上一篇文章中看到的那样:

This question has been already posted but I would like to know if there is a way to know if a directory exists on a remote machine with ssh BUT from the command line directly and not from a script. As I saw in this previous post: How to check if dir exists over ssh and return results to host machine, I tried to write in the command line the following:

ssh armand@127.0.0.1 '[ -d Documents ]'

但这不会打印任何内容.我想知道是否有一种容易显示答案的方法.

But this does not print anything. I would like to know if there's a way to display an answer easily.

推荐答案

这是一个班轮:

ssh armand@127.0.0.1 '[ -d Documents ] && echo exists || echo does not exist'
