I want to compare zone file counting and same name, not records etc of master and slave dns server so that i sure both server contains same copy of the files at a time.

any utility to compare such files in linix ?

I'm not sure I understand what you're trying to achieve, but the diff command will show the differences between 2 files. Have you tried that yet?

See also comm http://linux.die.net/man/1/comm

I would suggest checking the serial numbers if you want to know if
a slave has the same records as the master. Verify that the slave
uses the master in the configuration first. If they have the same
serial number, they should match.

If you simply want to compare two zone files, sort the first file
into a new file, sort the second file into a new file, and then
compare the two files using diff (or comm) as suggested above.

I want to achieve below:

server1 server2
a(files) a(files)
b b

d f

Both servers has almost same files . I want to see which files(name) are missing from server 1 and on server 2 as well.

You can use this:

Code:

diff -qr /path/to/dir1 /path/to/dir2
