Using csh / awk / sed to compare database sizes in a txt file
Hello,


I have an output file showing database sizes across the 3 environments that I use (LIVE, TEST & DEVELOPMENT).

I am trying to write a script that lets me know if the size of a db on one environment is different to its corresponding db on the other environments.

Here is an example of the file......(Name Size Environment)

Code:
stevie_db 13000   LIVE
stevie_db 13000   TEST
stevie_db 14000   DEVELOPMENT
john_db   25000   LIVE
john_db   25000   TEST
john_db   25000   DEVELOPMENT




I want to compare database sizes & flag up any databases that are a different size in any of the environments. So in the above example, the database stevie_db will be flagged up (because it is a different size in DEVELOPMENT). Maybe we could append an asterisk to any line that matches our criteria, to show it is different.


I imagine the general syntax would be something along the lines of
If $1 on line 1 = $1 on any other line

Compare $2 on lines 1 and the matching line, flag up an error if they are different sizes.

Move on to Line 2 (and so on).


Is this something that could be done in awk?


Any help would be really appreciated.

Cheers,
Stevie
