创建带有路径列表（嵌套目录）的文件

Question

I have a set of nested directories in a tree-like structure, and every directory at the bottom of the tree contains another directory called "dump".

I would like to create a file called "paths" with the all the paths to the "dump" directories, each one separated by a new line.

My attempt is:

echo ./*/*/*/dump | cat >paths

This kind of works, but the paths are not separated by a new line. How can I achieve this, possibly using echo and cat?

Answer 1

将echo与glob一起使用，并将其一次通过管道传送到xargs （ -n1 ）并将其写入文件为

echo ./*/*/*/dump | xargs -n1 > file

Answer 2

You can use find instead:

find . -type d -path '*/dump' > paths

or else just replace echo by printf in your glob :

printf "%s\n" ./*/*/*/dump >paths
