目录路径变量是否应该以斜杠结尾? [英] Should a directory path variable end with a trailing slash?

问题描述

在将目录的路径定义为变量或常量时，它应该以斜杠结尾吗?约定是什么?

When defining a path to a directory as a variable or constant, should it end with a trailing slash? What is the convention?

pwd显示的是当前目录，没有后加斜杠，而cd /var/www/apps/的制表符完整包含后跟斜杠，这让我不确定.

pwd in Unix shows your current directory without a trailing slash, while the tab complete of cd /var/www/apps/ includes the trailing slash, which left me unsure.

推荐答案

例如，当我定义用于存储文件的目录时，我不包括斜杠.那是因为我会像这样使用它

I don't include the trailing slash when I, for example, define a directory for storing files. That is because I will use it like

$store_file = "$store_path/$file_id";

在使用应该包含目录路径的变量之前，我总是会在末尾添加斜杠.我认为总要添加一个总比不知道是否包含结尾的斜杠好.

I will always add a trailing slash before using a variable that's supposed to hold a directory path. I think it's better to always add one than to wonder if the trailing slash is included.
