script needed to merge two files and report differences
Hello,

I have two txt files that look like this:

db.0.0.0.0:
Total number of NS records = 1


db.127.0.0.0:
Total number of NS records = 1
Total number of PTR records = 1


db.172.19.0.0:
Total number of NS records = 1
Total number of PTR records = 3


db.172.19.59.0:
Total number of NS records = 1
Total number of PTR records = 1

I would first like to merge two of them together side by side and at the end count from each on what is different and what matches and report:

For example the report could look like this side by side:

File A:
db.172.19.59.0
Total number of NS records = 1
Total number of PTR records = 1

File B
db.172.19.59.0
Total number of NS records = 1
Total number of PTR records = 1

And where there is a difference:

File A:
db.172.19.59.0
Total number of NS records = 100
Total number of PTR records = 23

File B
db.172.19.59.0
Total number of NS records = 101
Total number of PTR records = 26

Can this be done with Awk or Perl?

Thanks in advance !

Hi, I am working with this:

$ perl -00ne 'push @a,"$_\0$ARGV\n";END{print reverse split/\0/ for sort @a}' fileA.txt fileB.txt

But it wont give me side by side(left and right) its showing up/down

File A:
db.172.19.59.0
Total number of NS records = 1
Total number of PTR records = 1

File B
db.172.19.59.0
Total number of NS records = 1
Total number of PTR records = 1

And where there is a difference:

File A:
db.172.19.59.0
Total number of NS records = 100
Total number of PTR records = 23

File B
db.172.19.59.0
Total number of NS records = 101
Total number of PTR records = 26

any ideas or a better way?

Does this appear too complicated to accomplish?

After you paste something with definite positioning, highlight your text and then click on the # sign above for the smart-icon. The will put code-tags around your message and keep from reformatting and wrapping.
