1)list the maps/file on box1
2)list the maps/file on box2
3)List maps in both the environments
a) which are same
b)which are different

pls any ideas are appreciated

Use find to create a file that has checksums. Do it on box1 and then box2.

Code:

find /path/to/maps -type f  -exec cksum {} \; | awk '{print $3, $2, "box1" }' > box1.lis
find /path/to/maps -type f  -exec cksum {} \; | awk '{print $3, $2, "box2" }' > box2.lis

Next, merge the two files into one larger file with sort.

Now you can awk to find the duplicates, and the checksums tell you if the files are the same or not. box1.lis and box2.lis tell you the names of all of the files on each box.

If this did not so homework-ish, I'd show the awk code.

Hi Jim t
thanks for the reply,but there is a constraint which i forgot to tell you and that is , i must be on the source server only and need to remotely log onto the target server using the ssh command.
Thank You once again
