List only common parent directories for files

Question

0.00/5 (No votes)

See more:

I am searching for one file, say "file1.txt", and output of the find command is like below.

/home/nicool/Desktop/file1.txt
/home/nicool/Desktop/dir1/file1.txt
/home/nicool/Desktop/dir1/dir2/file1.txt

In above cases I want only common parent directory, which is "/home/nicool/Desktop" in above case. How it can be achieved using bash? Please help to find general solution for such problem.
