We covered globbing as this kind of filename expansion trick in the shell scripting and tools.

我在 shell 脚本和工具中介绍了通配符这种件名扩展技巧。

If we want to add a file, remove a file, change a filename, or similar, we have to update the information in the Directory File.

如果我要添加件、删除件、更件名或类操作，我更新目录件中的信息。

Here since the file has been fed through the script, and we don't know it beforehand, we have to substitute the variable of the filename.

由于件是通过脚本提供的，而我事先并不知道，因此我替换件名变量。

Yet someone had taken the time to alter the filename to read " HOPITAL SB. jpg" ; according to the timestamp, the photograph had in fact been taken a month-and-a-half prior.

然而，有人将件名为 “HOPITAL SB. jpg”；根据时间戳，这张照片实际上是在一个半月前拍摄的。
