Shell script to populate an array from a csv file
Hi Guys,

I've got a script that runs and collects statistics from one of our machines and outputs the data into a csv file. Now, that script runs fine and I managed to create another one (with a lot of help from this forum!!) to trim the csv file down to all the data that I need, rather than all the data it collects.

Anyway, I'm now trying to write a script to import this data from the csv file into Nagios so it can report the statistics. The easiest way I've heard of to do this is to create a script which involves populating an array from the csv file and then passing the contents of the array into Nagios (I can modify an existing script for that).

My knowledge on scripting is a bit limited and I certainly haven't created one involving passing a csv file into an array!! Does anyone have any pointers on how this can be done ? This is an example of the data in the csv file:
Code:
startup timestamp,1327702381482
cpu combined,0.0900
cpu idle,0.9100
cpu nice,0.0000
cpu sys,0.0360
cpu user,0.0540
cpu wait,0.0010
memory free,4415.501335 MB
memory max,4494.937500 MB
memory used,79.436165 MB

As you can see, there isn't a lot of data to insert into the array and I could possibly do without the first column as I can enter this in the Nagios script. Or, does anyone think there is a better way of doing this !?

Thanks for any help!

Cheers, Jim
