Question

The file which I am processing (param.txt) is tab delimited and the contents of the first column are _ delimited.

param.txt

ONE_one  two  three
FOUR_four  five  six
SEVEN_seven  eight  nine

I’ve created below script to process this file:

@echo off & setlocal enableextensions enabledelayedexpansion
for /f "tokens=1,2,3 delims=    " %%G in ('type param.txt') do (
  for /f "tokens=1 delims=_" %%a in ('echo %%G') do (
    echo %%a -- %%b -- %%H -- %%I
  )
)
endlocal & goto :EOF

This produces the below output:

ONE -- %b -- two -- three
FOUR -- %b -- five -- six
SEVEN -- %b -- eight -- nine

What needs to be rectified in the script to get it to print the “value” instead of %b?

Answer 1

Try replacing tokens=1 with tokens=1,2.

Note also that you can do the extraction with a single for loop, since you can specify multiple delimiters:

for /f "tokens=1,2,3,4 delims=_ " %%G in ('type param.txt') do (
  echo %%G -- %%H -- %%I -- %%J
)
