在批次：从路径和文件名可变的只读文件名 [英] In Batch: Read only the filename from a variable with path and filename

问题描述

我目前正在寻找一种方式来采用可变间歇，只解析出的文件名。

I am currently looking for a way to take a variable in batch and only parse out the filename.

例如，我通过我的批处理文件，从中随后被设置为我的源变量其他应用程序-s参数。源文件变量通常包含类似：C：\\ Program Files文件\\ MyApp的\\ Instance.1 \\ DATA \\ filetomove.ext

For example, I pass my batch file a -s parameter from another application which is subsequently set to my source variable. The source file variable typically contains something like: C:\Program Files\myapp\Instance.1\Data\filetomove.ext.

我想从变量，直到第一个\\末读取和结果设置为一个新的变量名，但我一直没能成功地使用了FOR / F条命令。

I assume to read from the end of the variable until the first "\" and set the result to a new variable filename but I have not been able to use the "for /f" commmand successfully.

任何帮助将是非常美联社preciated！

Any help would be much appreciated!

推荐答案

如果它进来作为参数传递给脚本，即％1％2，等等，你可以只提取文件名和扩展名改成这样的变量

If its coming in as an argument to the script, i.e. %1, %2, etc, you can extract just the filename and extension into a variable like this:

set FILENAME=%~nxN

其中N是参数的索引。例如，该脚本将呼应首个参数的文件名：

where N is the index of the argument. For example, this script will echo just the filename of the first argument:

@echo off
set FILENAME=%~nx1
echo %FILENAME%
