It's unclear what you mean by "number of changes". Number of changed lines? Number of changed characters? Number of changed regions?
Assuming the last of those (number of changed regions), one approach is to understand the output of diff. In Solaris diff (and most others, as I recall) the only lines that start with digits are the lines that specify the changed regions. so you can do this:
or
But in either of these, you are at the mercy of diff, which may not have the same idea about what a "region" is as you do. With more modern diffs than I have at hand, e.g., gnu diff, you have a lot more options to control what diff shows as a difference region.
All,
I have two csv files, the format of which are exactly the same.
I would like to find differences between the two files but would like to identify the difference as opposed to just printing a different line.
For exmaple
File 1
xxx,yyy,zzz,1,2,3
111,222,333,xxx,yyy

rcsdiff
rcsdiff(1) General Commands Manual rcsdiff(1)NAME
rcsdiff - compareRCS revisions
SYNOPSIS
rev1] rev2] file ...
DESCRIPTION
compares two revisions of each given RCS file and creates output very similar to (see diff(1)). A file name ending in is an RCS file name,
otherwise it is a working file name. derives the working file name from the RCS file name and vice versa, as explained in rcsintro(5).
Pairs consisting of both an RCS and a working file name can also be specified.
recognizes the following options:
Same as described in
diff(1);
Same as described in
diff(1);
Same as described in
diff(1);
Same as described in
diff(1);
Generate an edit script of the format used by
RCS.
Generate a diff with lines of context.
The default is to present 3 lines of context. To change, specify n; for example, gives 10 lines of context.
modifies the output format slightly from the normal diff(1) output. The ``context'' output begins with identification of the
files involved and their creation dates, then each change is separated by a line with a dozen (asterisks). Lines removed from
file1 are marked with (dashes); those added to file2 with (pluses). Lines that are changed from one file to the other are
marked in both files with (exclamation marks).
If both rev1 and rev2 are omitted, compares the latest revision on the trunk with the contents of the corresponding working file. This is
useful for determining what was changed since the last check-in.
If rev1 is given, but rev2 is omitted, compares revision rev1 of the RCS file with the contents of the corresponding working file.
If both rev1 and rev2 are given, compares revisions rev1 and rev2 of the RCS file.
Both rev1 and rev2 can be given numerically or symbolically.
EXAMPLES
Compare the latest trunk revision of RCS file and the contents of working file
Compare the revisions 1.1 and 1.2 in the RCS file
