Batch Files 1

[bobbytupper]

I want to create a batch file that can determine the version of the operating system. I dont want to use the %os% variable as it is same on Windows NT and Windows 2000.

I was thinking of outputting ver to c:\ver.txt and the using the contents of that file to determine the OS version.

I am stuck and any help would be muchly appreciated

Thanks

James

This should provide you with a starting point. I dont know what ver returns on NT4, so couldn't do that one.

****************************************************
@echo off
ver |FIND "Windows 2000" > nul
if not errorlevel=1 goto win2K

ver |FIND "Windows 9" > nul
if not errorlevel=1 goto win9x

echo Your operating system is not supported.
goto eof

:win2k
echo You are using win2k
goto eof

:win9x
echo You are using win9x
goto eof

:eof

Mate you are a star - I actually got around it by using if exist and referencing things like uniqe os files. This is what I really wanted to do though.

You you maybe explain in laymens terms what it is actually doing please.

Thanks again.

OK... all it does is takes the output of the &quot;ver&quot; command (which you have already found) and uses the output as the input to a FIND command. This is done using the pipe command |

The find command searches the input string for a match and sets errorcode to the return code of the FIND. As FIND normally prints the line that the match was found on I have used &quot;> nul&quot; to redirect the output to the nul device - basically just throws it away.

The IF statement checks to see what the previous line in the batch file set the errorcode to, and if it returned 0 executes the GOTO which jumps to the :win2k label. (this could be rewritten a number of ways i.e. if errorlevel 0 goto win2K - but I was always told to do it this way, and cant remember why!!!)

Brilliant - I did try and use the FIND command but couldnt figure out how to use the result ie if string not found set the error code. Obviously (now I wass missing the pipe. Thanks for your help Joc most kind!!

This is how I got around it and following using your method. I am using this to change proxy settings to point to a pac file and it works beautifully!
