Within AWK, how do you display a field of NR? Here's my code:


awk '(NR>1) && (P1=$1-w)>=100000 {print "increase of" " " P1*.0000179," " "kW at" " " 'NR*60/431900' " " "minutes" "\n" "change...

Thanks, brother, much obliged!

Good start! Thank you. Your code is cool, but it does not select the highest peak (line 5). It picks line 4 because it is the first to exceed 5000. Can it be written to pick line 5 (the biggest)...

I don't want to know every time the increase is over 5000. I want to know, of the points that exceed 5000, which is the highest within a range of 10 rows. Does that explain better?

I only...

Within millions of lines of data, there are perhaps 20 "spikes" that are very narrow. I want only the highest value from each spike within a range of 10 rows. Possible?

My data looks like this,...

Super impressed, Don. Thank you.

Yes indeed! Would you mind translating into English? I don't get how it knows what x is, and I don't see where the shift to the next line happens...Thanks a ton!

data sample, I modified the second column for simplicity:

1.94183e+05 7.8e+04 1.09609e+04 -2.51962e+03 2.58938e+03 -1.78130e+04 8.17326e+03 9.09750e+03
1.95223e+05 7.8e+04 1.08129e+04 ...

This is for research. The data is power and its odd harmonics, and I am looking for a way to ID transients without having to graph everything. I just chose simple numbers so I can understand the...

Total UNIX Rookie, but I'm learning. I have columns of integer data separated by spaces, and I'm using a Mac terminal.

What I want to do:
1. Compare "line 1 column 2" (x) to "line 2 column 2"...
