Could somebody point me in the right direction where to find information
on the scripting “language” supported by QNX4.2x. Things like “if test
-b … fi”, etc. that are found in files like the ph script.
Also, I am making a call like “system(dinit -h /dev/hd0t78)” in C++ but
it doesn’t work correctly. I’m thinking the system call is returning
before the true 4GB partition is “dinit’ed”. I am looking for some kind
of confirmation or wait command that the dinit is done. I don’t want to
use “delay(guess a time here)” for obvious reasons.

I believe all of the scripting stuff is just using ksh shell
programming,
so if you took a look in the helpviewer under ksh, that would probably
work. Others
can correct me if I am wrong on this.
If you need to wait for the command to finish, you might want to
investigate the spawn
commands. If memory serves me correctly, the first argument to spawn
can be set to wait
until the command executed has completed ( ie. P_WAIT ).
Hope that helps.

ksh will have minimal content, and a link to sh, where the actual
description is. It is, basically, a public domain Korn shell.
If you need to wait for the command to finish, you might want to
investigate the spawn
commands. If memory serves me correctly, the first argument to spawn
can be set to wait
until the command executed has completed ( ie. P_WAIT ).
system() should also wait for the command to finish.

That’s completely wrong. There are at least the following scripting
available for QNX4 and QNX6:

My apologies for my limited usage of “all”, Armin - I guess I was
referring to all of the sh scripting information found in the help
files, not in regards to other scripting languages, which I believe is
what the fellow was asking about. I will try to be more explicit in
future.
The “standard” QNX shell is based on the korn88 shell
With this in mind there is a good O’Reilly & Associates book
called “learning the Korn Shell”, although there a few implementation
difference but it provides another perspective.
Often within my programs, I shell out with a system command.
Especially when dealing with files and already available qnx commands
(rather than rewriting)
