Petre, please solve this asap.  Yarda is not here this week

Working on it

Seems I have a solution not using expr at all, simpler and faster.
Still testing...

Hmm, I hate bourne shell.
Need another solution, my simple and nice solution needs bash,
I only happened to have bash as /bin/sh on my solaris box ;-)

I believe I've fixed it properly now. Please test it.
core/launcher/unix/nbexec,v1.9

Still one expr index is used in the script.

Fixed even the second occurence, hope it is OK now.

verified on Sparc Solaris

IFS solution seems to be much better than mangling with expr. Thanks
that the issue got to you -Petr, but I have executed following statement:

save=$IFS; IFS=':'; for i in x:y:z ; do echo $i; done; IFS=$save

and received:

x y z

maybe I did some mistake, but should not I get
x
y
z
instead? What is really needed is to iterate over all --clusters. Does
there really work or we are not seeing immediate problems (unknown
agruments to a command) on solaris?

I can't see any shell problems, this is, what I tested.
I haven't tested functionality of the NetBeans itself, I suppose
it'll be done by QE.

OK, Yarda, the problem is that your script use the modified IFS also
for the inner loop commands, while in my patch, I do reset the IFS
from inside the cycle. That way, the modified IFS is used for the
setup of the loop, yet it is correct the the function called from the
loop.
Try putting some echos in the nbexec (e.g. inside the ..._pre_...)
to verify passed agrs (so it is called for each cluster) and to check
IFS. I did so and it was OK.

If we are at the bourne shell teaching course now ;-) one more note.
Your example didn't work, as the literal 'x:y:z' was never processed
using IFS, your loop was run only once and when $i was once
substituted for echo, it was turned into three arguments.
As you see, it has to go through the substitution to actually apply
IFS, so try this:
list="x:y:z"; save=$IFS; IFS=':'; for i in $list ; do echo $i; done;
IFS=$save

er even better:
list='x:y:z'; save=$IFS; llist=$list; IFS=$save; for i in $llist; do
echo --$i--; done

Is it clear now?

Yes.

OK, just for fun, a short historical note:
The very original Bourne Shell (that unportable thing running on
PDP-11) even applied IFS to literals, so command
IFS='o' viola
would start vi on file named "la"
