start /wait does not wait :-(

[Yandos]

Hi,

I've been asking for help on xp-general group, but without luck, so I'm trying it here...

I have the batch file which is executed every half an hour on a server (win2003) to do some backups:

-----8<-----
@echo off
echo compress1
C:\WINDOWS\system32\cmd.exe /c start "zip" /wait /b /low "C:\Program Files\7-Zip\7z.exe" a -t7z "-
m0=PPMd" "-mmem=32m" "-mo=8" "-mhe=on" -- backup1.7z "c:\dir1\*.*"
echo compress2
C:\WINDOWS\system32\cmd.exe /c start "zip" /wait /b /low "C:\Program Files\7-Zip\7z.exe" a -t7z "-
m0=PPMd" "-mmem=32m" "-mo=8" "-mhe=on" -- backup2.7z "c:\dir2\*.*"
ping 127.0.0.1 -n 100
echo do something...
pause
-----8<-----

7z.exe (compress program) eats too much cpu, so I need to run it as a low priority task to preserve
computer response for other tasks. It is executed as a low priority task, BUT it does not wait for
7z.exe's end. What's wrong with my batch?

Thank you in advance.

Y.

The cmd.exe /C creates a _NEW_ shell which exeutes the start "zip" etc.
detached.
The new shell will wait, but there is no follow up.

The batch itself has nothing to wait for.

Simply remove the "cmd.exe /C" part.

Try it without "C:\WINDOWS\system32\cmd.exe /c"
