[Cuis-dev] Using OSProcess package

[Jan Vraný]

Hi, 

how does one use OSProcess package in Cuis? I have loaded it but it does 
not seem to work - all I get for

    OSProcess command:'ls -al'

is this in console:
    
    bad env or bad args: Bad file descriptor

In Squeak, it does work.

Besides, how is one supposed to wait for the command to 
finish (provided it starts in the first place)?

Thanks! Jan
