Title: Shell script problem
Post by: dandelion on January 28, 2004, 03:12:01 PM

Hi all..

I need a bit of help with the script i'm writing. It doesn't do much, simply executes a file which then holds the process until the program finishes. The thing is, i need this program to be executed within another program, which means that the parent program is held up until the program it launches quits. However, the fact that the parent program is held up causes major problems.

So...what i'm trying to do is get the parent program to launch the other program without it effect its own operation. Is there a "new process" command or a way of doing this?

Hope this makes sense, didn't explain it very well!

The command 'Run' perhaps?

Edit: And if you are using OS3.9, adding a '&' behind the command should do the exact same thing.

Program &

Whereas with Run you would type:

Run Program

aye.

Run mystoopidprogram >Nil:

and that will launch it in it's own shell, and keep it quiet.

To execute a program detached from a script, use Run.

Run >NIL: Foobar

This runs and detaches Foodbar and stops run itself from outputting anything.

Run >NIL: Foobar >NIL:

This makes the whole thing totally quiet, but isn't usually necessary - detached tasks mostly have nowhere to send their output to anyway.
