6/17/2006 12:14:00 PM


if from a ruby script, i do :

server="/Volumes/HDX/Users/yvon/MacSOUP_news.individual.net/individual"

nntp=`egrep -i -o --binary-files=text -e "news\.\w+\.\w+"
"#{server}/..namedfork/rsrc"`.chomp

p "nntp = " + nntp


i get "" (empty answer)


if i write a bash script "getNntpAddress.sh" with the following :

#!/bin/bash

nntp=`egrep -i -o --binary-files=text -e "news\.\w+\.\w+"
$1/..namedfork/rsrc`
echo $nntp


and use it from ruby by :

nntp=`/Users/yvon/work/RubyCocoa/MacSOUPSwitcher/map/getNntpAddress.sh
#{server}`.chomp

p "nntp = " + nntp


i get the correct answer "nntp = news.individual.net"

There's really no need to call egrep from Ruby. This makes things more
complicated and less efficient than needed. Why don't you just do this:

server="/Volumes/HDX/Users/yvon/MacSOUP_news.individual.net/individual"
nntp=File.read("#{server}/..namedfork/rsrc")[/news\.\w+\.\w+/]

p "nntp = " + nntp

Kind regards

You're an islamotard and/or nazitard, please drown yourself
in chlorine to eliminate yourself from the gene pool.

Good advice. Trying it yourself might be a fine idea, cornhole.
Criminally insane ZioNazi turds always think killing solves their
many problems.

Unfortunately when dealing w/psychopathic islamoturds or
naziturds there really is no other choice.
