maxdepth is a GNUism, so if you don't use Linux, or if the depth may be different:

Code:
find . -type d -name t3 | xargs -I{} find {} -type f -name t4

or:

Code:
find . -type f -name t4 | grep /t3/t4$

Why do you "need" the output using -prune, when other solutions exist?

-prune option

Hi,
I am learning about -prune option. So only i asked that specifically. Can please give me a samle command which demonstrates the -prune option? ?

this was your ans for my question.
Code:
find -mindepth 3 -maxdepth 4 -iname "t4"

But u need not specify maxdepth. the following will work well , which is an alteration of ur ans.
Code:
find -mindepth 4 -name "t4"

You don't need prune. Just tell find to only search the directory you require.

Code:
find ./t1/t2/t3 -name t4 -print

Output is:
./t1/t2/t3/t4
