bash路径

I am writing a Bash accepting input of a path from the user. I want to make the path have no trailing ‘/’, such as ‘/path/to/dir’ instead of ‘/path/to/dir/’.

我正在编写一个Bash 接受来自用户的路径输入。 我想使路径没有尾随“ /”，例如“ / path / to / dir”而不是“ / path / to / dir /”。

However, as the input is from the user, the input could be ‘/path/to/dir’. My script is intended to handle this.

但是，由于输入来自用户，因此输入可能是“ / path / to / dir”。 我的脚本旨在解决这个问题。

The question is: how to remove the trailing ‘/’ if the input indeed has it? When the input has not trailing ‘/’, it should be fine.

问题是：如果输入确实包含后缀“ /”，如何删除？ 当输入的末尾没有尾号“ /”时，应该没问题。

You may do in a straight forward way like check whether the last character is ‘/’ and the path is a to a directory and remove that ‘/’ from the .

您可以采用简单的方式进行操作，例如检查最后一个字符是否为'/'，并且路径是否为目录的a，然后从删除该'/'。

But here I provide another much easier method:

但是在这里，我提供了另一种更简单的方法：

`dirname $path`/`basename $path`

will consistently gives the same path without the trailing ‘/’ no matter whether the path is a directory or a file without or without the trailing ‘/’.

不管路径是目录还是没有尾随'/'的文件，都将始终给出相同的路径而没有尾随'/'。
