我想使用批处理脚本/cmd 从目录中的每个 txt 文件中删除最后一个字符

Question

I have some .txt files for example:

a.txt
b.txt

Each line of these files contain numbers in the below format:

9999999999,  
1111111111,

I want to remove , after each number by way of a batch script.

The result should be like:

9999999999
1111111111

Answer 1

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION 
FOR %%e IN (u:\a.txt u:\b.txt "u:\your files\c one.txt") DO (
 >u:\dummy.tmp (
 FOR /f %%y IN ('TYPE %%e') DO (
  SET "line=%%y"
  ECHO !line:~0,-1!
 )
 )
 MOVE /y u:\dummy.tmp %%e >nul
)

GOTO :EOF

Always verify against a test directory before applying to real data.

Filenames are my test files.
