Difference between run and exec

[xwb]

Is there some internal difference between run and exec in wshshell? I'm using them with secure shell. The secure shell program takes about 10 minutes to run and then comes back.

When I use run, it reports and end of file error. When I use exec, it runs to completion. The only difference I can see is that with exec, you have control over the I/O but why should it make so much difference to ssh?

With EXEC you have the option to wait for execution to complete. With RUN your script will just continue to the next line of code.

I hope you find this post helpful.

Maybe not quite true. Check out run's 3rd parameter.

I am running with 3rd parameter false and waiting for the program to terminate. Problem is that ssh says I've lost the connection when I use run but not when I use exec.

Maybe it is something to do with the synchronous nature of run and asynchronous nature of exec.

I don't have any further information to add than what has already been mentioned, but I wonder how you're calling the ssh app exactly??

.Run "sshapp.exe xxxxx"
.Exec "sshapp.exe xxxx"

or

.Run "%comspec% /c sshapp.exe xxxx"
.Exec "%comspec% /c sshapp.exe xxxx"

Tried it both ways (except I used cmd.exe instead of %comspec%. The result is the same.

I'm now using the exec method but I'd really like to know why ssh loses the connection when I use run.

I am running with 3rd parameter false
I'd use True ...

Hope This Helps, PH.
