Hi, so I have created a batch file to replace each occurence of the SUBSTRING "sid" in a reg file with the usersid.
The only problem is some of the DATA gets truncated.
Consider this batch file:

@echo off
;Get sid from file
set /p usersid=
SETLOCAL DISABLEDELAYEDEXPANSION
FOR /F %%L IN (sandboxie.reg) DO (
SET "line=%%L"
SETLOCAL ENABLEDELAYEDEXPANSION
ECHO !line:sid=%usersid%!>>out.reg
ENDLOCAL
)
ENDLOCAL


out.reg:

As you can see, the string: @="\"C:\\Program Files\\Sandboxie\\Start.exe\" /box:__ask__ Explorer.exe \"%1\""
gets truncated to: @="\"C:\\Program
in out.reg

How do I fix the script to get proper output?Same truncation will OCCUR on any line containing a space.

Space is one of the default delimiters in a For loop so as soon as the space after Program is encountered that's the end of the line.

Suggest you use For /f "tokens=*" .....etc so that the text line is TREATED as one and not delimited.

Welcome to the CH forums & hope this helps.Appreciate! That worked Thanks for coming back to REPORT your success..
