I have a file that has multiple lines, of grouped data, that typically all have the same values in the 1st field, however, I would like to search the 1st field for any differences and set a flag to use in an "if" statement to run some other routine.
An example of the typical file is below, which is a comma separated file:
I want to set a flag for each data set of the 3rd field, if the file has differences in the 1st field like below:
One method I've tried so far is to strip out the lines where the 3rd field is all the same, and then try to run through each line and check the 1st field for differences.
I've tried the following, but can't get it to work.

Reason: Add awk method used
Dears,
I have a list as follows,

If I want to find the difference between two consecutive rows. Then I have to store the specific rows in two variables and then find the difference. Could someone tell how this can be done.

I have two files. They are prety much the same, except a few lines. I would like to get the differences between the two file, but only those differences and nothing more.
"diff" and "sdiff" cannot seem to do it. "sdiff -s" gets close, but I still get "less than" or "greater than" signs in the... (2 Replies)

Hi,
I have a file in the following format
a1 b1 c1 d1
a2 b2 c2 d2
a3 b3 c3 d3
a4 b4 c4 d4
I need a script to find the difference between corresponding values of successive rows. So the output would have one less row than the input file and should look like:

Hi!
I'd like to know if it is possible for a command to find the first difference between two large files, output that line from both file and stop, so no need to continue after that to save some computation time.
I don't think looping through it will be efficient enough but that's the only... (6 Replies)

merge
MERGE(1) General Commands Manual MERGE(1)NAME
merge - three-way file merge
SYNOPSIS
merge [ options ] file1 file2 file3
DESCRIPTION
merge incorporates all changes that lead from file2 to file3 into file1. The result ordinarily goes into file1. merge is useful for com-
bining separate changes to an original. Suppose file2 is the original, and both file1 and file3 are modifications of file2. Then merge
combines both changes.
A conflict occurs if both file1 and file3 have changes in a common segment of lines. If a conflict is found, merge normally outputs a
warning and brackets the conflict with <<<<<<< and >>>>>>> lines. A typical conflict will look like this:
<<<<<<< file A
lines in file A
=======
lines in file B
>>>>>>> file B
If there are conflicts, the user should edit the result and delete one of the alternatives.
OPTIONS -A Output conflicts using the -A style of diff3(1), if supported by diff3. This merges all changes leading from file2 to file3 into
file1, and generates the most verbose output.
-E, -e These options specify conflict styles that generate less information than -A. See diff3(1) for details. The default is -E. With
-e, merge does not warn about conflicts.
-L label
This option may be given up to three times, and specifies labels to be used in place of the corresponding file names in conflict
reports. That is, merge -L x -L y -L z a b c generates output that looks like it came from files x, y and z instead of from files
a, b and c.
-p Send results to standard output instead of overwriting file1.
-q Quiet; do not warn about conflicts. -V Print 's version number.
DIAGNOSTICS
Exit status is 0 for no conflicts, 1 for some conflicts, 2 for trouble.

BUGS
It normally does not make sense to merge binary files as if they were text, but merge tries to do it anyway.
