-====== Linux - Find - Find all zero size files ======
-<code bash>
-find ./ -type f -size 0

-or
-<code bash>
-find ./ -type f -empty
-</code>
-This commands will find all zero size files in the current directory with sub-directories and then print the full pathname for each file to the screen.
-  * **./**  means start searching from the current directory. If you want to find files from another directory then replace the ./ with the path to needed directory.  For example, to search everything under the system log directory you need to replace ./ with /var/log.
-  * **-type f**  flag specifies to find only files.
-  * **-size 0** and **-empty** flags specifies to find zero length files.
-To find and then delete all zero size files, there are variants you can use:
-<code bash>
-find ./ -type f -size 0 -exec rm -f {} \;
-find ./ -type f -size 0 | xargs rm -f
-find ./ -type f -size 0 -delete
-</code>
-  * The xargs will cause all the filenames to be sent as arguments to the **rm -f** commands.  This will save processes that are forked every time **-exec rm -f** is run.  But it fails with spaces etc in file names.
-<WRAP info>
-**NOTE:**  **-delete** is the best option when it is supported by the find you are using.
-It avoids the overhead of executing the **rm** command by doing the **unlink()** call inside **find()**.
