Check numeric fields greater than zero, and delete lines if appropriate
This be the latest in my problems sorting through router logs... I'm half way there on a problem, but I've hit the limitation of my knowledge
Got some router interface log files of type
I don't care about frame errors or ignored errors, but I do want to take account of input errors, CRC errors and overrun errors, so I want to keep those lines (and the line above them) where those parameters are non zero, and I want to delete those lines where the important parameters are 0, and the lines above them. So... for the input above... I want the output to be
I'm thinking the way to do it is to sort for lines with the string "input errors", and check if the second, or fifth, or ninth parameters are non zero, and if so keep that line and the line above it, otherwise delete the line and the line above it.
I'm doing this on ubuntu... (may or may not be relevant)

Reason: Please use code tags!
Both solutions work... but with a proviso... the log file contains similar lines but with the other types of errors seen on Cisco interfaces as well... and all these lines are deleted also. I just want to delete the lines I mentioned...
I'm guessing both solutions use a sort of 'delete everything else'. I just want 'delete line n and line n-1'
