Subject: catch stderr

Hi,

I have some question about catching stderr output in ruby... Please read
the following simple code.

STDERR.reopen STDOUT
result=`net use abc`
print "res=", result

while abc is not available on my LAN. I didn't succeed in catch the
stderr output to my program.

I searched the talk archive, found some discussion, but I still have
doubts. I refered to post #47612 and #47578, and copied the first line
of code above. It does not work. Moreover, in sample code from #47578, I
found some key words I don't recognize, such as "ensure... end" and
"redirect... end". I tried to search these in the html help of ruby
(came with the windows install package), but can't find any info. I also
need some suggestion on how to find info in the help file. Last time I
tried to find reserved word "in", in the help file, also failed... :(
