Hi thanks
I put those output in a router file

so i edited like this

#!/usr/bin/ruby

member,slot="",""
File.readlines("router").each do |linecrlf|
  line = linecrlf.chomp
  case line
    when /^member/ then member=line
    when /^Slot/ then   slot=line
    when /Memory utilization/
      puts "%10s %10s %s" % [member,slot,line.gsub(/\b+percent/,"%")]
  end
end



but it shows

ruby router_check.rb
router_check.rb:10: invalid regular expression; there's no previous 
pattern, to which '+' would define cardinality at 3: /\b+percent/
