如何使用Windows命令查找文本文件中的字符串，并复制接下来的5个字符 [英] How to find string in text file with Windows command and copy next 5 characters

问题描述

我有input.txt：

I have input.txt:

asdfasfasdfa,abc12345,abc98591,abc13456,abc95934,abc53455  
safasdfasdfa,abc31212,abc55455,abc23124,abc54834,abc13689  
...

我需要output.txt：

I need output.txt:

12345  
98591  
13456  
95934  
53455  
31212  
55455  
23124  
54834  
13689  

所以我需要找到所有的abc字符串并复制下5个字符）到新文件，每个数字必须在新行。

so I need find all "abc" string and copy next 5 charcters (after "abc") to new file and each number must be in new line.

推荐答案

查看：

@echo OFF &SETLOCAL
FOR %%f IN (*.txt) DO (
    ECHO Processing %%f --^> %%~nf.txt.new
    (for /f "usebackq delims=" %%a in ("%%~f") do call:doit "%%a")>"%%~nf.txt.new"
)
GOTO :EOF

:doit
SET "line=%~1"
SET "first=true"
:loop
SET "token="
FOR /f "tokens=1*delims=," %%b IN ("%line%") DO (
    SET "token=%%b"
    SET "line=%%c"
)
SET "out=%token:~-5%"
IF NOT DEFINED first ECHO(%out%
SET "first="
IF DEFINED line GOTO :loop
GOTO :EOF
