awk - how to get difference of the same column when other column matches
I have a file like this :
and I want output like this :
Only when the first and second column matches, I should take a difference of fourth column in the consecutive matching rows.
How will I achieve it. ?
I tried this :
This works. But i may not know the contents in the runtime. Hence it has to check if column1 and column2 matches and then do a diff.
Please help

Hello,
I have 2 columns (1st column has multiple entries but the corresponding values in the column 2 may be the same or different.) however I want to extract unique values for each entry in column 1 by assigning the max value from column 2

Can anyone please help with this? I have 2 files as given below.
If 2nd column of file1 has pattern foo1@a, find the matching 1st column in file2 & replace 2nd column of file1 with file2's value.
file1
abc_1 foo1@a ....
abc_1 soo2@a ...
def_2 soo2@a ....
def_2 foo1@a ........ (7 Replies)
Hey folks. I wrote a little awk script that summarizes /proc/net/dev info and then pipes it to the nix column command to set up column spacing appropriately.
Here's some example output:
