Another issue

I have another batch file I am trying to get working. All I am really trying to do is check a version on a flash drive then update it to the latest version. For some reason it closes before hitting the pause. I have the pause in there to help trouble shoot. Any suggestions?

cls
@echo off
cd sbusb
@echo ----- This is not ready to be used Please close by using RED X ------
@echo.
@echo What drive letter is your flash drive?
set /p dr=
copy %dr%:\version.txt H:\ITM03\Programs\BootDisk\
type version.txt> %ver%
pause
if '%ver%'=='378' goto 379
if '%ver%'=='379' goto 380
if '%ver%'=='380' goto 381
if '%ver%'=='381' goto 382
if '%ver%'=='382' goto 383
if '%ver%'=='383' goto 384
if '%ver%'=='384' goto 385
if '%ver%'=='385' goto 386
if '%ver%'=='386' goto 387
if '%ver%'=='387' goto 388
if '%ver%'=='388' goto 389
if '%ver%'=='389' goto end
:378
:379

and so on

%ver% is not defined.

I think you want this:

for /f %%a in (version.txt) do set ver=%%a

not this

type version.txt>%ver%

what does the %%a mean / do?

So I just removed the % signs and it works. The type is setting ver. Or at least seems to be.

type version.txt> ver

ok so it is closer. The program stays open but it is not going to the correct spot. it runs 378 then 379. I want it to jump to the correct version. I tried what you suggested Larry but that did not work either

It doesn't work -- it just continues on but doesn't do what you want.

type version.txt> ver

No, it's not setting a variable. It's redirecting the output of the type command into a file called "ver".

You probably have to add the drive letter to make it work:

Code: Select all

for /f %%a in (%dr%:\version.txt) do set "ver=%%a"

To see what ver gets set to you can:

echo %ver%

If it's not working, you can remove the @echo off and perhaps see more of what's happening. Otherwise you may have to post your version.txt file to see if it's the problem.

That works great now. Thank you so much for your help. And thank you for the link that describes what they do.
