Hi all, I have a text file which shows the output of many commands. I'm trying to capture from this output, the number of volumes on a host along with the size of each volume, so I can then figure out capacity based on each host. here is a sample of the text file: 
host_output
volume_name   host_name
vol1          host1
vol2          host1
vol3          host1
vol4          host2
vol5          host2
vol2          host2

volume_output
volume_name size
vol1        10g
vol2        20g
vol3        30g
vol4        30g
vol5        20g

(of course these are just simple examples). This info (along with alot of other info) is in one file in the format similar to what I show above. How can I parse through this? I was trying to have a hash that lists all the volumes for a host, and then tries to look up the size of each volume but I'm not getting anywhere with it. Any ideas on what the best way to approach this would be? Thanks much!
