But, I need to know the total number of collisions of all the NICs. ...
How many NIC's do you have?

Do you have a preference? Theoretically, anything you can do in a script, can do on the CLI. It's just not convenient.
Are you looking for a command/script that will take a list interfaces (NIC's), find their collision counts, add up those counts, & output that sum? And do you want verbiage, like "Total collisions for interfaces eth0 & eth1 = nnn"?
Good. Unless the NIC's are consecutively #'d, you will need to supply a list of their names rather than a count; the list could be permanent. Perhaps a little more background on what you will be doing, especially how it might change from 1 use to the next.
Now for the big Q: how good are you at bash scripting & how much help do need in writing it?
