I have two text files to compare: file A and file B
file A is nicely formatted with sections, headings etc, for better visibility
file B is a linear raw list of strings (really a bunch of machine names)
I am trying to compare file A and file B, and locate the strings in each file that don't exist in the other, and vice versa-- in other words, identify unique strings in each file.
UNIX utility *diff* works great, so do Windows tools like 'ExamDiff', 'CompareIt!' etc; but they only compare a single occurence of each string pair, and ignore the rests.
For instance, I have
List A List B
------ ------
abc bcd
def def
def ijk
ghi jkl
The result will be:
List A List B
------ ------
abc bcd
def ijk
ghi jkl
(Note that the eliminated strings were the ones that followed One-to-One matching)
While the expected result is:
List A List B
------ ------
abc bcd
ghi ijk
jkl
With both occurences of 'def' being eliminated - with One-to-many comparison.
Can anyone suggest a solution? A tool or an script logic?
