Extract difference of two columns from different rows
Hello guys,
Please help me to solve this problem. I have tried some awk commands but couldn't succeed.
I have a tab delimited file where each record is separated by ------ and 4th column of each record is same.
<INPUT FILE>
I want an output file where rows are added corresponding to each record. An examlpe output file is -
Here, 3rd column is same as 4th column of input file
2nd column is calculated by subtracting 3rd column of row starting with SDS
from 2nd column of row starting with peon i.e. (53932031-53931821 = 210) in case of second record. This has to be calculated for all the
SDS-peon pairs in each record. Value zero is assigned if there is only 1 row in a record i.e. SDS-peon pair is missing.
Dears,
I have a list as follows,
2
4
8
If I want to find the difference between two consecutive rows. Then I have to store the specific rows in two variables and then find the difference. Could someone tell how this can be done.

a2-a1 b2-b1 c2-c1 d2-d1... (4 Replies)
