Question

I need execute two commands on Windows 7 startup (with .bat file):

route delete 0.0.0.0 192.168.5.201
route -p add 192.168.4.0 mask 255.255.0.0 192.168.5.201

If first route doesn’t exists on system – .bat file doesn’t executes properly. First command executes on infinity loop.
How can i check if this route exists and then execute first command?

P.S. or maybe there is another way to do it without .bat file?

Answer 1

I cannot reproduce the infinite loop here; for me it just exits with an error.

But you can check for a particular route with

route print 0.0.0.0 192.168.5.201

However, that alone won’t be enough as the exit code of route is always 0. So you have to pipe through findstr:

route print 0.0.0.0 192.168.5.201 | findstr 192.168.5.201

Afterwards you can either check errorlevel:

if not errorlevel 1 route delete 0.0.0.0 192.168.5.201

or chain the command:

route print 0.0.0.0 192.168.5.201 | findstr 192.168.5.201 && route delete 0.0.0.0 192.168.5.201
