Finding files and directories alternate method

Finding files and directories in Linux – alternate method

Find empty directories in the current directory using find -empty

find . -type d -empty

Use the following command to remove all empty directories under the current directory.

find . -type d -empty -exec rmdir {} \;

Note: It is not recommended to remove empty directories from /etc/ or any other system directories.

Find empty files in the current directory using find -empty

find . -type f -empty

Note: Typically empty files are created by some programs as place holders, or as lock files, or as socket files for communication.

How many empty files are located under the current directory (and sub-directories)?

To count the number of empty files under current directory, pipe the find command to wc -l

find . -type f -empty | wc -l

How many non-empty files are located under the current directory (and sub-directories)?

find . -type f -not -empty | wc -l

Note: Find option -not reverts the option that follows it.

In all the above examples, replace the ( . ) dot with any other directory-path under which you would like to search the files.
