如何寻找/批处理文件替换文本时处理＆符号？ [英] How to handle ampersands when finding/replacing text in batch file?

问题描述

我有以下批处理文件找到，并在一个文本文件中删除的字符串。该文本文件将在以下格式来：

  079754，计费和放大器;商务进阶..，E：\\ MyDirectory \\ 079754_35931_Billing＆安培;商务进阶... PDF，PDF合并
 

我只是想去掉E：\\ MyDirectory \\从文件，然后将文件移动到子目录。我的批处理文件，按预期工作，除了那里是在文件中的符号的情况下（如一个以上）。

而不是包含我的结果文件：

  079754，计费和放大器;商务进阶..，计费和放大器;商务进阶... PDF，PDF合并
 

相反，它包含了，

  079754，计费
 

我有些新的编写批处理文件和我认识的符号影响以某种方式标记化。任何帮助将大大AP preciated！

批处理文件：

 关闭@echo
CD C：\\ TEMP \\经纪商
在%% F（* .DAT）做（
    如果存在newfile.txt德尔newfile.txt
    FOR / F令牌= * delims =%%一中（%% f）作@call：改变一%%
    德尔%%˚F
    重命名newfile.txt %%˚F
    移动%% F进口\\ %% F
）退出/ B
暂停：更改
设置文本=％〜1
设置文本=％文本：E：\\ MyDirectory \\ =％FOR / F令牌= 3 delims =%% d。在（％文本％）做@set文件= %%ð
（回声％文本％）GT;＆GT; newfile.txt
将％文件％，进口\\％文件％
退出/ B
 

解决方案

您应该enquote像设置，以躲避＆放命令; 和其他特殊字符。结果
并使用延迟扩展，延迟扩展的特殊字符将被忽略。结果
并且执行了块之前百分号展开评估，所以你的for循环如预期不能工作。

  SETLOCAL EnableDelayedExpansion
...：更改
设置文本=％〜1
设置文本=文本：E：\\ MyDirectory \\ =！FOR / F令牌= 3 delims =%% d。在（！的文字！）做@set文件= %%ð
（文呼应！）GT;＆GT; newfile.txt
动！文件！ 进口\\！文件！
退出/ B
 

I have the following batch file to find and remove a string in a text file. The text files will be coming in the following format:

079754,Billing & Business Adv..,E:\MyDirectory\079754_35931_Billing & Business Adv...pdf,Combined PDF

I simply want to remove "E:\MyDirectory\" from the file and then move the file to a subdirectory. My batch file works as expected except for the case where there is an ampersand in the file (such as the one above)..

Instead of my result file containing:

079754,Billing & Business Adv..,Billing & Business Adv...pdf,Combined PDF

It instead contains,

079754,Billing 

I am somewhat new to writing batch files and I know the ampersand affects the tokenizing in some way. Any help would be greatly appreciated!

Batch File:

@echo off
cd C:\Temp\broker
for %%f in (*.dat) do (
    if exist newfile.txt del newfile.txt
    FOR /F "tokens=* delims=" %%a in (%%f) do @call :Change "%%a"
    del %%f
    rename newfile.txt %%f
    move %%f "import\%%f"
)

exit /b
pause

:Change
set Text=%~1
set Text=%Text:E:\MyDirectory\=%

FOR /F "tokens=3 delims=," %%d in ("%Text%") do @set File=%%d
(echo %Text%)>> newfile.txt
move "%File%" "import\%File%"
exit /b

解决方案

You should enquote commands like set, to escape the & and other special characters.
And use the delayed expansion, as with delayed expansion the special characters are ignored.
And percent expansion is evaluated before a block is executed, so your for-loop can't work as expected.

setlocal EnableDelayedExpansion
...

:Change
set "Text=%~1"
set "Text=!Text:E:\MyDirectory\=!"

FOR /F "tokens=3 delims=," %%d in ("!Text!") do @set File=%%d
(echo !Text!)>> newfile.txt
move "!File!" "import\!File!"
exit /b
