仅列出文件的公共父目录 [英] List only common parent directories for files

问题描述

我正在搜索一个文件，比如file1.txt，并且find命令的输出如下所示。

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

在上面的例子中我只想要共同的父目录，在上面的例子中是/ home / nicool / Desktop。如何使用bash实现？请帮助找到这个问题的一般解决方案。

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.

解决方案
