Differences between 2 Flat Files and process the differences
Hey Guru
Sorry for the confusion but
what I meant to ask was that
Code:
'NR==FNR{a[i++]=$1" "$2" "$3" "$4;next;}
by this you store first 4 columns of the whole file(all rows)
and then you move to the next
Code:
{x=$1" "$2" "$3" "$4; for (j in a){if (a[j] == x)next;}}1'
where you store the first 4 columns of each row of second file in x and compare them against the all rows(but first 4 columns only) one by one
what does this 1' means and after executing this awk script the final
file that we will have only 4 columns or the whole structure of the file
(it should compare only the first 4 columns but in the final file should have all 6 columns)
Thanks
J

Hi,
"diff" command takes two file names as arguements and gives the difference between the two.
How do I get the number of differences between two files ???
(Excluding whitespaces).
Don't ask me to count number of lines produced by "diff".
Thanks in advance,

All,
I have two csv files, the format of which are exactly the same.

For exmaple
File 1
xxx,yyy,zzz,1,2,3
111,222,333,xxx,yyy

Hi everyone,
I know that's a deep treated issue but I'm actually not able to find the solution. I have 2 plain text files with ~ 2000 rows and ~5 columns. The first column of the shortest file (f1) is fully contained by the first column of the biggest one (f2), but only that column. I want to... (6 Replies)

When viewed in Topas it's consuming 99.*% cpu
But if I try using

I have 2 files that need to be compared. Email the differences if something is different and don't email if nothing is different. One or both of the files could be empty. One or both could have data in them.
