batch file - Modifying a .bat script to add a bit of text of my choosing to the output -


i posted question part of code further down , got brilliant response helped me solve problem. there bit of debate validity of code below moment works me , concerns in free time.

@echo off >nul find "var want_spring_aid_file_update = 1;" "input.txt" && (   >>output.txt (  /f usebackq^ tokens^=2^ delims^=^" %%a in ( 'findstr /c:var front_spring_aid_file = ^"part_name1^"; "input.txt"') echo %%a ) )

the problem needed solve code probe text file presence of string , based on result grab or not string between double quotes specific line of same text file , drop in new text file. now, title explains, add bit of text of choosing output.

basically have following code in input text file:

var want_spring_aid_file_update = 1; var front_spring_aid_file = "part_name1"; var rear_spring_aid_file = "part_name2";

my current script checks if string in first line present , if probe second line , grab string between "" , drop in new text file.

how can add bit of text of choosing on same line? if outputs part_name1 how can add the model updated part that?

based upon , previous related question, how following work you?

@echo off  set "fi=input.txt" set "vm=var want_spring_aid_file_update " set "fm=var front_spring_aid_file " set "sm=var rear_spring_aid_file " set "fo=output.txt" set "so=the model updated part"  /f "tokens=2delims==;" %%a in (     'find /i "%vm%"^<"%fi%"') set/a vd=%%~a 2>nul if not "%vd%"=="1" exit/b  >"%fo%" (   /f tokens^=2delims^=^" %%a in (         'findstr/ilc:"%fm%" /c:"%sm%" "%fi%" 2^>nul') echo %so% %%a)

it retrieves 2 values required, if value of want_spring_aid_file_update 1.

[edit] - (tested win7)

here entire content of input.txt:

// commented line var want_spring_aid_file_update = 1; var front_spring_aid_file = "part_name1"; var mid_spring_aid_file = "part_name1.5"; var rear_spring_aid_file = "part_name2";


and output.txt:

the model updated part part_name1 model updated part part_name2
