Hello,
we have found out that on some Windows 2000 computers (particularly
very fast laptops with rather slow hard disk), the result of a command
in backquotes isn't put into the variable associated reliably. A
command like
UNAME=`uname`
will return the correct result most of the time, but will sometimes
return an EMPTY result! It looks like a race condition where the
shell tries to read the program's output before the subprocess for
uname is finished... This is extremely annoying and makes it
impossible to write reliable shellscripts!
The problem is very hard to reproduce. It seems to turn up only
on few computers, and only with lots of disk access around the
"backquote sections".
Is this problem already known, and what can we do to fix it?
I can try and put together a simple shellscript for reproducing
the problem, if needed.
Best regards,
Martin Oberhuber
