dirname

The dirname of the script being executed.

当前正在执行脚本所在的目录名。

The dirname function returns the directory name from a path.

函数的作用是：返回路径中的目录名称。

It´s companion, called dirname, returns the "other" part of the path that basename throws away.

它的相关命令dirname返回basename丢弃的“另”一部分路径。

Each path element contains a single dirname element, so the code searches for elements named dirname and grabs the first entry.

每个path元素包含了一个dirname元素，所以代码搜索名称为dirname的元素，并获取其中的第一个条目。

While basename and dirname are great tools, there are times where we may need to perform more advanced string "chopping" operations than just standard pathname manipulations.

尽管basename和dirname是很好的工具，但有时可能需要执行更高级的字符串“截断”，而不只是标准的路径名操作。
