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

diff
DIFF(1) General Commands Manual DIFF(1)NAME
diff - print differences between two files
SYNOPSIS
diff [-c | -e | -C n] [-br]file1 file2
OPTIONS -C n Produce output that contains n lines of context
-b Ignore white space when comparing
-c Produce output that contains three lines of context
-e Produce an ed-script to convert file1 into file2
-r Apply diff recursively to files and directories of
EXAMPLES
diff file1 file2 # Print differences between 2 files
diff -C 0 file1 file2
# Same as above
diff -C 3 file1 file2
# Output three lines of context with every
diff -c file1 file2 # Same
diff /etc /dev # Compares recursively the directories /etc and /dev
diff passwd /etc # Compares ./passwd to /etc/passwd
DESCRIPTION
the same name, when file1 and file2 are both directories" difference encountered"
Diff compares two files and generates a list of lines telling how the two files differ. Lines may not be longer than 128 characters. If
the two arguments on the command line are both directories, diff recursively steps through all subdirectories comparing files of the same
name. If a file name is found only in one directory, a diagnostic message is written to stdout. A file that is of either block special,
character special or FIFO special type, cannot be compared to any other file. On the other hand, if there is one directory and one file
given on the command line, diff tries to compare the file with the same name as file in the directory directory.
