I am new to windows batch scripting and am having trouble extracting information from a text file. My script needs to iterate over a text file with an unknown number of lines and search for the string “Installer ID:”. Once this is found I need to store whatever information is on the right hand side of the colon.

For example if my text file looked as follows:

SomeText.txt
------------------------
Installer Date: 2010_10_24_24345
OXF BUILD ID: OXF-12223
Installer ID: OTFI-316
Excel  ID: 2-10186
BUILD DBID: 296414
Version: 6.2

I would want to store:

OTFI-316

I have come so far with something like this:

@echo off
setlocal EnableDelayedExpansion
set file=build_info.txt
FOR /F "tokens=*" %%i IN (%file%) DO (
findstr Installer ID: %%i
if %errorlevel%==0 (
set installer_id=SUBSTRING I
)

but I am having problems searching %%i for “Installer ID:” with its two words and colon, and from there I am unsure how to properly substring %%i.

    Put the FINDSTR command within the FOR IN() clause, and parse the results.

    I set DELIMS to colon and space so that all of the following lines would give the correct result:

    Installer ID: OTFI-316
Installer ID:OTFI-316
Installer ID:      OTFI-316

    You want everything after the 2nd token (the * in tokens=2*).

    @echo off
set "file=build_info.txt"
set "installer_id="
for /f "tokens=2* delims=: " %%A in (
  'findstr /bc:"Installer ID:" "%file%"'
) do set "installer_id=%%B"
