Topic: Array of Hashes

Hi There,

man I did quite some searching, but I wasn't able to find the answer to my question. Maybe you can help me out?

Here's my code:

        plist= {
                "jboss"  =>  {"pid"  => ""},
                "apache" => {"pid" => ""}
               }
        keys=plist.keys
        begin
        plist.each_key { |key|
          pidlist=`ps -ef | grep #{key} | awk '{print $2}'`
          pidlist.each do |pidname|
                puts "pid to add " + pidname
#                plist[key]["pid"] = plist[key]["pid"] + pidname.chomp.to_i
#                plist[key]["pid"] << pidname.chomp
                 plist[key]["pid"] << pidname.chomp
          end
                       }
        puts plist.inspect
          true
        rescue Errno::ESRCH
          false
        end

I'd like to create an hash of arrays like this:
{"jboss"=>{"pid"=>"3361", "4937", 5710"}, "apache"=>{"pid"=>"3365"}}

The best thing i could create was this:
{"jboss"=>{"pid"=>"336149375710"}, "apache"=>{"pid"=>"3365"}}

As you can see, all the values for "pid" are concatenated.. sad
What am I doing wrong?

Thank you in advance!

Re: Array of Hashes

Lol, tried some more. Thing I did wrong was the initial declare of pid.
I did:

        plist= {
                "jboss"  =>  {"pid"  => ""},
                "apache" => {"pid" => ""}
               }

should be:

        plist= {
                "jboss"  =>  {"pid" => []},
                "apache" => {"pid" => []}
               }

Thanx anyway!
