Count Number Of Files In A Directory And Its Size

[myworld]

To find a folder's size?

A directory ("folder", if you like) is a file like all the others, just a somewhat "special" one. It's own size is rather small, but if you'd like to know the size of all of it's contents (recursively), you can use 'du':

du /path/to/directory
or
du testdir

That prints

10264 testdir/

or in human-readable form:

du -h testdir

that prints

11M testdir

Now i wanted to count the number of files in the targetdir directory.

$ ls -1 targetdir | wc -l

The above command reads ls dash one piped to wc dash letter l.

Note that if you had used ls dash letter l instead, the count is one greater than the actual number of files. This is because ls dash letter l outputs an extra total line:

$ ls -1 targetdir

The above method will count symbolic links as well as subdirectories in targetdir (but not recursively into subdirectories).

If you want to exclude subdirectories, you need a heavier duty tool than ls.

$ find targetdir -type f  -maxdepth 1 | wc -l

-type f ensures that the find command only returns regular files for counting (no subdirectories).

By default, the find command traverses into subdirectories for searching. -maxdepth 1 prevents find from traversing into subdirectories. If you do want to count files in the subdirectories, just remove -maxdepth 1 from the command line.

Note that the find command does NOT classify a symbolic link as a regular file. Therefore, the above find -type f command does not return symbolic links. As a result, the final count excludes all symbolic links.

To include symbolic links, add the -follow option to find.

$ find targetdir -type f -follow  -maxdepth 1 | wc -l
