Sorry. That was a horrible way to ask for help on something. Now that I'm trying, I find it's harder to ask properly than I thought.

My CSV files look like:

IP,Domain,ServerName
10.160.0.8,0,
10.160.0.9,0,
10.160.0.10,EURORSCG,ERWWDC1
10.160.0.11,EURORSCG,ERWWSQLWEB
10.160.0.12,EURORSCG,ERWWSEARCH
10.160.0.13,EURORSCG,ERWWNAB
10.160.0.14,EURORSCG,ERWWCOMMUNITIES

and

The files get inputted as hash arrays, %hosts and %sysinfo. I'd like to combined both into %combined, using the IP column as a key. I'd like it to look like:

IP,Domain,ServerName,DaysUptime,OS,RAM,OSSP,InstallDate,CPUSpeed,CPUCo
+unt,CPUType
10.160.0.8,0,
10.160.0.9,0,
10.160.0.10,EURORSCG,ERWWDC1,19,Microsoft_Windows_2000_Server_Domain_C
+ontroller,1024,4,12_2_2003,995,1,Intel_Pentium_III
