Differences between 2 Flat Files and process the differences
Hey Guru
Sorry for the confusion but
what I meant to ask was that
by this you store first 4 columns of the whole file(all rows)
and then you move to the next
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

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.

gifdiff - compares GIF images

gifdiff [options] GIF-file-1 GIF-file-2
DESCRIPTION
gifdiff compares two GIF files and determines if they appear identical. Differences that don't affect appearance (like colormap ordering or
how much an animation is optimized) are not reported.
gifdiff prints details of any differences it finds. If the GIFs are the same, it prints nothing. It exits with status 0 if there were no
differences, 1 if there were some differences, and 2 if there was trouble.
OPTIONS --brief, -q
Report only whether the GIFs differ, not the details of the differences.
--ignore-redundancy, -w
Do not report differences in the numbers of redundant frames (frames which do not change the displayed image).
--help
Print usage information and exit.
--version
Print the version number and some quickie warranty information and exit.
