st: Re: Run the -shell- command in parallel on Unix

["Sergiy Radyakin" <Radyakin@aoek.uni-hannover.de>]

Hi,
are you using a GUI version? If so, winexec is supported (quote from
help winexec):

        Stata for ...
       command    Windows    Macintosh    Unix(GUI)    Unix(console)
       -------------------------------------------------------------
       shell         X         X            X            X
       winexec       X         X            X            -
       xshell        -         -            X            - 
       -------------------------------------------------------------


Doesn't "command &" do what you want? See here:
http://www.washington.edu/computing/unix/startdoc/shell.html
(section "Run a Process in the Foreground or the Background")

But if not, one can also implement it. The trick is that Stata waits
for the task to complete, so the task which is launched from Stata
must just pull the trigger, and let the OS to control the process.
In windows we do it with ShellExecuteEx, in Unix with a fork()
function:
http://www.cim.mcgill.ca/~franco/OpSys-304-427/lecture-notes/node16.html

So, all you need to do is to create a small C-program, which will
receive one parameter (name of the task) -- launch it as a child
process and terminate without waiting. I am sure it exists already,
just need to have a look into the Unix manual. (in Windows it is
called -start-, internal in XP, external in W9x/Me).

Regards,
  Sergiy
