Batch For Loop Splitting on Tab Delimiter

Question

I am attempting to write a batch script that uses a for loop to read in lines from an input file. I want to split each line that is read in on a tab delimiter. The input file is formatted as shown below with a tab between sourcefile and version. There is also an endline character after version.

sourcefile1   version1
sourcefile2   version2
sourcefile3   version3

I am running the following batch file.

@echo off
 for /F "tokens=1,2 delims=\T^" %%a in (input_file.txt) do ( 
   echo a = %%a 
   echo b = %%b 
)

My output is as follows:

a = sourcefile1 version1
b =
a = sourcefile2 version2
b =
a = sourcefile3 version3
b =

My desired output is:

a = sourcefile1
b = version1
a = sourcefile2
b = version2
a = sourcefile3
b = version3

Any input on how I can achieve my desired output? Thank you

Answer 1

您需要使用cmd /F:OFF制表符完成来启动 Cmd，然后使用"tokens=3 delims=^T" ，这里^T将是制表符文字。

Answer 2

Removing the delims options gave me my desired output

@echo off
for /F "tokens=1-2" %%a in (input_file.txt) do (
   echo %%a
   echo %%b
)
