Shell Programming and Scripting

Thanks ilan, I think I got it. In order to use tabs in awk it's awk -F"\t"

Thanks everyone for your help, it was greatly appreciated.

Code:

awk 'BEGIN{FS="\""}
{
a[$5]++
if (a[$5]<=1)
	print
}' file

Hi,

I do have an idea to resolve this issue. Taking the uniq values of the third column with the help of awk, sort and uniq. Grep the values in the original file using for loop and use head -1 to get only first entry values out of duplicate entires


Here, I took the entries in the file named duplicate.txt

$ cat duplicate.txt
1 ralphs office","555-555-5555","ralph@mail.com","www.ralph.com
2 margies office","555-555-5555","ralph@mail.com","www.ralph.com
3 kims office","555-555-5555","kims@mail.com","www.ralph.com
4 tims office","555-555-5555","tims@mail.com","www.ralph.com

I followed the below procedure at command prompt....

$ for id in ` cat duplicate.txt | awk -F, {'print $3'} | sort | uniq`
do
grep ${id} duplicate.txt | head -1
done

Output I got as follows:

3 kims office","555-555-5555","kims@mail.com","www.ralph.com
1 ralphs office","555-555-5555","ralph@mail.com","www.ralph.com
4 tims office","555-555-5555","tims@mail.com","www.ralph.com
$


Hope, this works...


Thanks,
Aketi.

I have data like this:
It's sorted by the 2nd field (TID).

I want to do the following:
Check the second field to see if the TID is the same as the previous line. If the TID has been seen before then check the 7th field to see if that is the same as the previous line. If both are the same, I want to remove the line and increment a counter.

My ideal output would look something like this.
11,envoy,90000000000000634600010001,04/11/2008,23:19:27,RB00266,0015,DETAIL,ERROR,

etc.

I figure I actually need to do an awk script rather than a 1 liner. The other option is for the last 3 fields to be one field and compare by the TID field and the error field, then split them into 3 on the output.

Any thoughts? I've looked at other stuff removing dups with awk and it's mostly one liners.

I'd love to ask get some explanation of WHY it works so that I can mod it if need be.

kinksville,

Please don't hijack another ones thread, but start a new thread for your problem.

Thanks.

Sorry about that, I'm happy to start a new thread, I hadn't wanted to post something that was already being answered.
