[BASH] How to read multiple lines from a text file?

[gtirsmiley]

For example, I have a text file with data which lists numerical values from two separate individuals

Person A
100
200
300
400
500
600
700
800
900
1000
1100
1200

Person B
1200
1100
1000
900
800
700
600
500
400
300
200
100

How would I go about reading the values for each Person, then being able to perform mathematical equations for each Person (finding the sum for example) ?

Thanks.

Bash isn't really well suited to that, but awk will do it easily. You need just 2 lines in your awk script: one matching numeric lines which adds the numbers to your running total, the other matching text lines which prints the result and zeros the counter.
