| Sorry, I can't reproduce your problem.
| Could you show me your `ruby -v'?

I'll do better than that :-)

(But "ruby -v" is in the middle...)

Summary     : Object Oriented Script Language
Description :
Ruby is the interpreted scripting language for quick and
easy object-oriented programming.  It has many features to
process text files and to do system management tasks (as in
Perl).  It is simple, straight-forward, and extensible.
# ruby -v
ruby 1.4.3 (1999-12-08) [i586-linux-gnu]
# cat others.rb
#!/usr/bin/ruby

# Interesting problem reached here...
#
# ARGV is [ "arg1", "arg2", "arg3" ]
# results from a scan are [ [ "str1" ] ]
#
# Thus, ARGV.each is "arg1" ... "arg2" ... "arg3" ...
# scanXX.each is [ "str1" ] ... [ "str2 ] ...
#
# Thus ARGV[0] is "arg1" ; scanXX[0] is [ "str1" ] ;
# and scanXX[0][0] is "str1"
#
# This explains a lot.

systems = Array.new

class String
   def systemName
      self.scan("^... .. ..:..:.. ([^ ]*)")
   end
end

File.open("/var/log/messages").each { |line|
   line.chomp!
#  sys = line.scan("^... .. ..:..:.. ([^ ]*)")
   sys = line.systemName

   systems = systems | sys

   if not ARGV.include?(sys[0][0])
      print("    ", line, "\n")
   end
   }

# (systems.sort!).each { |sys|
#    print("   ", sys, "\n")
#    }

I thought that first bit was interesting - a run that was interrupted
with control-C (SIGINT) had no such "Abort" or "[BUG]" message.

I might note that I am also working in ruby under HP-UX ... so don't
always assume I'm using Linux :-)

Is ruby available for Unixware as a Unixware package?  I found
an RPM for Linux (obviously) and a Software Depot for HP-UX.
Is there a package for FreeBSD? (just curious)
