Hi everyone, I'm a new member at the forum I mistakenly posted this elsewhere too.
I have a file like this: field 2 values are either 0 or negative. file test4:
I would like to print a line containing the maximum value in field 2 of all occurrences for each value in field 1. So the desired output should be:
I am using awk to do this. But, there are two problems: first awk prints nothing when I try to get the maximum for the values with negative numbers but it has no problem when I try the same with positive numbers. This made me take the absolute values which I can later turn back to the original values. The second problem, I get the following output with my code:
Although with absolute values I should get:
My code is:
I am sure I'm missing something basic and this could probably be done in a much simpler way. Any help is appreciated

That is because by default, the order in which a for (i in array) loop scans an array is not defined; it is generally based upon the internal implementation of arrays inside awk.
I've the files in a directory in the following format having date +%Y%m%d%H
YR_MNTH_2013061205
YR_MNTH_2013060107
and i need the latest file i.e; YR_MNTH_2013061205 to be moved to another folder
#!/bin/ksh
# Ksh 88 Version
for test_time in YR*
do
---
done
How can i achieve that !... (2 Replies)

Hi,
I'm attempting to search, using awk, a pattern range in a file. Something like:
>awk '/first bit of text.../,/...last bit of text/' file
Is it possible to print only the last (or first) occurrence of the pattern range this way?
Thanks for any suggestions.
