What output do you get from the 'same files' diff?
Code:
diff -s --exclude --recursive --brief -b dir1 dir2 | head -10

Code:
diff -s --exclude --recursive --brief -b dir1 dir2 | head -10

Code:
Common subdirectories: dir1/aix and dir2/aix
Common subdirectories: dir1/envsql and dir2/envsql
Common subdirectories: dir1/java and dir2/java
Common subdirectories: dir1/ora and dir2/ora

Apparently there's nothing to delete, so xargs is getting a blank input (which is something I didn't consider).

Change the xargs call to:
Code:
xargs -r echo rm

and it should get rid of the error for this case.

I see no files being deleted. There are many files that are similar in dir1 and dir2 and none of them got deleted.

Attached is the zip I created for your reference. It has two directories dir_1 and dir_2. If a compare is run between dir_1 and dir_2 , the only files that should be present in dir_2 after the compare should be the files inside dir_2/ora/seq/

What is the --exclude for? With no parameters that appears to be excluding everything, at least on my diff (GNU diffutils 3.3).

Without that it works as expected:
Code:
$ diff -s --recursive -b dir_1 dir_2
Files dir_1/java/abc/test/Constants.java and dir_2/java/abc/test/Constants.java are identical
Files dir_1/java/abc/test/constants_1.txt and dir_2/java/abc/test/constants_1.txt are identical
Files dir_1/java/abc/test/delete.java and dir_2/java/abc/test/delete.java are identical
Files dir_1/java/abc/test/test.java and dir_2/java/abc/test/test.java are identical
Only in dir_1/ora: java
Only in dir_2/ora: seq
$ diff -s --recursive -b dir_1 dir_2 | awk '/identical$/ {print $4}' | xargs echo rm
rm dir_2/java/abc/test/Constants.java dir_2/java/abc/test/constants_1.txt dir_2/java/abc/test/delete.java dir_2/java/abc/test/test.java
