Re: [Pharo-users] OSProcess / OSSubprocess / LibC uniqueInstance

Thank you.

The Metacello snippet helps. It loads a newer version than that from the catalog browser.

But 2 more questions:

1.: Is there a reason not to use just ...

LibC uniqueInstance system: 'zip -r 123.zip zipme/'

... ?

And 2.: Is it ok to use OSSubprocess on in 64 bit images even though the documentation says it doesn't work ? (but it does)

    Hi Serge, Albrecht,

    loading OSProcess directly with the following expression works:

    Metacello new
        configuration: 'OSProcess';
        repository: 'http://www.squeaksource.com/MetacelloRepository';
        load

    There is still some work to be done on OSProcess adaptation to Pharo
    7, but they are in rarely used parts.

    Regards,

    Thierry
