批处理文件FOR / F扩张 [英] Batch file FOR/f expansion

问题描述

我有一个文件（ directories.txt ）与目录的名称，每个名称在一行，我想扩大行

I have a file (directories.txt) with directory names, each on a single line and I like to expand the line

C:\Documents and Settings\%USERNAME%\My Documents

在我的脚本运行脚本的真实用户名。然而回声出来完全一样的行和％USERNAME％不展开。

In my script to the real user name running the script. However the echo comes out exactly the same as the line and %USERNAME% does not expand.

FOR /f "tokens=*" %%X IN (directories.txt) DO (
    ECHO %%X
)

回波显示C：\\ Documents和Settings \\％USERNAME％\\我的文档，而不是C：\\ Documents和Settings \\ JANCO \\我的文档

任何想法？

推荐答案

我已经成功地做​​到这一点使用变量替换：

I've managed to do this using variable substitution:

SETLOCAL ENABLEDELAYEDEXPANSION

FOR /f "tokens=*" %%X IN (directories.txt) DO (
    SET DIR=%%X
    ECHO !DIR:%%USERNAME%%=%USERNAME%!
)
