Subject:	[OT?] make bash script wait for called program to finish?
From:	Thomas L Roche <tlroche AT us DOT ibm DOT com>

How to make a bash script wait for a program that it calls to finish?
Why I ask:

Don't ask me why this process is structured this way, but, in order to
install some code that I need in order to test my code, I hafta

a wget an (executable) extractor and some (non-executable) binaries

b run the extractor on the binaries. This runs some InstallShield UI
  that no one I know seems to know how to script. This creates an
  installer and a set of disk images.

c run the installer on the images. Fortunately this part I know how to
  script.

What I'd really like to do is script the whole thing, because each
step takes about 30 min, but step b eludes me. So what I'd like my
script to do is

0 wget

1 launch the extractor UI, which I will briefly twiddle

2 wait for the extractor to finish

3 check that the installer and images were created

4 run the installer on the images

I know how to script everything but 2: how can I do that?

Apologies if this is a FAQ: if so, please pass a pointer. If possible
please post to me as well as the list, and TIA.
