Question

I need to write a batch script to copy those lines from a pipe-delimited file that have one of two given ID numbers.

For example, for this file:

Jack | 12 | Jacksonville
Jane | 34 | Minneapolis

The ID numbers that have to be hardcoded are 12 and 56.
So a new text file has to be generated will contain this:

Jack | 12 | Jacksonville

Suggestions?

Answer 1

All ID’s matching either 12 or 56 in the file IDFile.txt will be outputted into a new file MatchingIDs.txt.

@echo off
setlocal enabledelayedexpansion
set line=0
for /f "tokens=2 delims=|" %%a in (IDFile.txt) do (
set num=%%a
set num=!num: =!
if !num!==12 set bool=true
if !num!==56 set bool=true
if "!bool!"=="true" call :GETLINE
set /a line+=1
set bool=false
)

:GETLINE
if not %line%==0 set skip=skip=%line%
for /f "%skip% tokens=* delims=" %%b in (IDFile.txt) do (
echo %%b >>MatchingIDs.txt
goto :BREAK
)
:BREAK
