[GEM Development] batch file question (for OpenGEM 4)

[Shane M. Coughlan]

Hi guys

I'm trying to work out how to add some lines to GEM.BAT so it'll look in a 
folder for a file, and if the file is there it'll execute another batch 
file.  If the file is not there it'll just continue loading GEM.  This will 
be a feature for the automatic detection of new updates and applications.

I can't remember how to do it!

Is something like this along the right lines?

IF EXIST C:\GEMAPPS\GEMSYS\UPDATE\UPDATE.ZIP GOTO UPDATE ELSE GOTO 1

:UPDATE
UNZIP C:\GEMAPPS\GEMSYS\UPDATE\UPDATE.ZIP -d
GOTO 1

:1



Orrrrrrrrrr should it be something using ERRORLEVELS?

Please help!

Regards

Shane
