Finding a String in a File

[RaynotRoy]

I'm currently working on a batch program to automatically rename download hotfixes to their 8.3 file name. So far, i have the file being renamed, the .cat file extracted and both being placed in the i386\svcpack directory. i also have the files and their nessesary switches being automatically entered into svcpack.inf, then compressed to svcpack.in_.

Heres were the problem comes in:

dosnet.inf needs the line:

[OptionalSourceDirs]
svcpack

When this program is run more than once, it adds that string twice. How can i tell it to search for that string in dosnet.inf, and add it if the string is not found, but if it is found then it should leave the file alone?

You can do that with nircmd.exe or Fedit.exe.

Do you know the command used? I searched the help file in nircmd, and didn't find anything

to add:

nircmd.exe inisetval I386\winnt.sif Section_Name Value_Name Value

to delete:

nircmd.exe inidelval I386\winnt.sif Section_Name Value_Name

Its a lot better and accurate than something like this in cmd language

findstr /i "^svcpack$" "UWXPCD\I386\dosnet.inf"
if '%errorlevel%' neq '0' (
  echo.>> "UWXPCD\I386\dosnet.inf"
  echo [OptionalSourceDirs]>> "UWXPCD\I386\dosnet.inf"
  echo svcpack>> "UWXPCD\I386\dosnet.inf"
)
