simple question about OSProcress

Hi!

I am considering in using OSProcess to run an external application.
I have tried:
        OSProcess waitForCommand: 'ls -l’
but this expression never return a value.

I also tried:
        OSProcess command: 'ls -l /etc’

But it returns an ExternalUnixOSProcess.  I am not sure what I can do with this. How can I get the result of the unix command?

Sorry if these questions looks naive :-)

Cheers,
Alexandre

Hi,

Maybe you should try to access: ExternalUnixOSProcess >>initialStdOut or exitStatus?

Cheers,
Vincent

Hi Alex,

try the following: (PipeableOSProcess command: 'ls -l /etc/') output

This works on OS X and on Linux, don’t know if it does on Win.

Be careful with this. IIRC, depending on the command and how much output it returns, you can easily freeze your image. Do some experiments (e.g. #waitForCommand: vs. #command:, non-blocking output). There are ways to make it more robust, depending on the exact situation. Search the archives for something like "PipeableOSProcess nonblocking". HTH
