I agree with RudiC that your specification (in both post #1 [after 20 edits] and in post #12) saying:
Quote:
if Column 3 has value= P then check column 7,8,9,10,12,13 (values should be zero in each) and hence sum of these columns should be zero.
if Column 3 has value= N then check column 7,8,9,10,12,13 (values should be zero in each) and hence sum of these columns should be zero.
appears to be a mistake. And to get the output you said you want, it would seem that if field #3 is N, you really want to check 7, 8, 9, 10, 11, and 13 instead of checking exactly the same fields for both P and N.
Assuming that that is correct, here is another awk script using the same underlying logic as the code RudiC suggested. This script builds the array of fields to be skipped for each letter than appears in the string in field #3 manually. RudiC's script depends on an extension to the standards (using an empty ERE in split() to create an array from single characters in a string) that is available in GNU awk but is not often supported on versions of awk available on UNIX systems and BSD-based systems. The standards say that the behavior of awk is unspecified when split() is called with an empty string specified as the field separator.
Unlike RudiC's code, this adds a new column to the header line as shown in the output header you said you wanted. And, while RudiC's code adds up all of the fields being checked, this code looks at each field individually and breaks out of the loop immediately if a non-zero value is found in a field that is to be checked.
The following awk script:
when file contains the sample input you provided, produces the output:
which seems to match the output you said you wanted.
If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

@Don ..Yes you and Rudi were right about P and N . Your code is working fine only one issue when I am running it, it is giving me list of files in that directory and gives the output.
Could you please create a script for example script.ksh, paste script there then give it executable permissions eg-->chmod 755 and then run Rudi's/Don's code, it should fly without showing anything else then.
Thanks,
R. Singh

doing something like below
Pasting a script that contains tabs into a shell that uses tabs to trigger command completion is not going to work. As Ravinder suggested, copy my script into a file and execute the file.
You haven't told us what operating system or shell you're using, but I test it out with the following in a file named tester:
make it executable with:
and then executing it with:
produces the output I showed you in post #15 in this thread. If you invoke it with an operand that is the pathname of a different file to be processed:
it will process the data in otherfile instead of the data in a file named file.

I would like to compare values in column 8, and grep the ones where the different is > 1, columns 1 and 2 are the key for array.

Dear Unix experts,
I have got a file where I would like to compare the values of second column if first column is same in such a way that the difference between the values is >50. If not, I would like to discard both values.

Hi all !
If there is only one single value in a column (e.g. column 1 below), then return this value in the same output column.
If there are several values in the same column (e.g. column 2 below), then return the different values separated by "," in the output.

Hi,
I have a table in unix from which i want to read the contents line by line, then filter out the values from 6th column one by one and compare it a fixed value.
How to do this? (7 Replies)
