Create a symbolic link of directory in Ubuntu
提问by
Below is my code for creating a symlink of a directory:
下面是我创建目录符号链接的代码：
sudo ln -s /usr/local/nginx/conf/ /etc/nginx
I already created the directory /etc/nginx. I just want the contents of the source directory (/usr/local/nginx/conf/) to be in the contents of the target directory (/etc/nginx). But when I execute the code, /etc/nginxcontains a directory called conf, instead of the contents of conf. That directory contains the contents I want, but in the wrong location.
我已经创建了目录/etc/nginx。我只希望源目录 ( /usr/local/nginx/conf/) 的内容位于目标目录 ( /etc/nginx)的内容中。但是当我执行代码时，/etc/nginx包含一个名为 的目录conf，而不是conf. 该目录包含我想要的内容，但位置错误。
Why did it put a directory in the target folder, instead of just putting the contents of the directory in the target folder?
为什么要把目录放在目标文件夹中，而不是直接将目录的内容放在目标文件夹中？

This is the behavior of lnif the second arg is a directory. It places a link to the first arg inside it. If you want /etc/nginxto be the symlink, you should remove that directory first and run that same command.
这是ln如果第二个 arg 是目录的行为。它把一个链接到第一个参数里面。如果您想/etc/nginx成为符号链接，您应该先删除该目录并运行相同的命令。

That's what lnis documented to do when the target already exists and is a directory. If you want /etc/nginxto bea symlink rather than containa symlink, you had better not create it as a directory first!
ln当目标已经存在并且是一个目录时，这就是记录要做的事情。如果你想/etc/nginx以成为一个符号，而不是包含一个符号，你最好不要将其创建为一个目录第一！

In script is usefull something like this:
在脚本中是这样的有用的东西：
if [ ! -d /etc/nginx ]; then ln -s /usr/local/nginx/conf/ /etc/nginx > /dev/null 2>&1; fi
it prevents before re-create "bad" looped symlink after re-run script
它可以防止在重新运行脚本后重新创建“坏”循环符号链接之前
