Using "enviroset" in DOS Batch File

[Jill McCrea]

Can anyone tell me of a good, resourceful place to go on the internet to
find out how to use "enviroset" in a DOS batch file? I need to write a
batch program (and obviously I'm a newbie) that will call a setup.exe (no
problem) but then I need the batch program to search the machine for a
specific text file and then based on whether or not the text file was found,
I need to set a DOS variable to yes/no, true/false whatever, to represent
finding/not finding the text file.
Much thanks,
Jill

newsgroup.

Dear Jill,
As I am no programmer, I am not sure what you mean, but for verifying the
existence of a file you can use the "ifexist" command of DOS:

ifexist <drive, path, filename> then <whatever command>

(I used it in DOS 6, but a warning: When I tried it with diskettes it worked
only if any diskette was in drive A: and if A: was empty, the batch file
came to a halt. Probably you can fix that, using errorlevel or error code
returns.

Make it easy,
Erol

Here's an example for the c drive.

DIR/A-D/B/S c:\*.* |FIND.EXE "filename.any" >nul
IF not errorlevel=1 SET found=yes
