hi Monks

I have a question regarding the use of hashes and whether this approach is feasible, I need to write a small piece of code which processes a list of servers, and for each server runs and command and pulls back what components are running against that server and pattern matches just the component name from the list

Example
Server A       Component1 
           Component2 
           Component3 
           Component4 

Server B       Component1 
           Component2 
           Component3 

Server C       Component1
           Component2

And so on. The code I have is below

#!/usr/bin/perl
$logfile="/tmp/gatherinfo.log";
@srvlist = ('serverA','serverB','serverC');
open(LOGFILE,">>$logfile")||die ("cannot create and open file");
foreach $_ (@srvlist){
        chomp $_;   
        @cmd = `pulldata -e $_`;
        foreach $line (@cmd)
        {
             chomp ($line);
             if ($line =~ '^\s+(\w+):\s.*')
                                {
                      $RM=$1;
                      <ASSIGN TO HASH AND PRINT>
                      print LOGFILE <hash content>
                                }
                        }
                }
}
close(LOGFILE);

I know hash uses key=value so what im looking to do is dynamically assign server stored in default variable $_ as key into the hash and the component value ($RM) as value and print it. Is this a pragmatic approach?
