How to Count Files in Directory in Linux

Although not very often, there are times when you need to find out how many files are in a given directory. For example, if you run out of inodes on your Linux system, you’ll need to find which directory contains thousands or millions of files.

In this article, we will show you several different ways to find the number of files in a directory in Linux.

Count Files in Directory #

The simplest way to count files in a directory is to list one file per line with ls and pipe the output to wc to count the lines:

ls -1 DIR_NAME | wc -l

The command above will give you a sum of all files, including directories and symlinks. If you want to count only files and not include the directories you could use the following:

ls -1p DIR_NAME | grep -v / | wc -l

The -p option tells ls to append slash (/) indicator to directories. The output is piped to the grep -v command that exclude the directories.

ls -1 also doesn’t count hidden files (dotfiles).

To have more control over what files are listed, you can use the find command instead of ls:

find DIR_NAME -maxdepth 1 -type f | wc -l

-type f option tells find to list only files (including dotfiles), and -maxdepth 1 limit search to the first-level directory.

Recursively Count Files in Directory #

To recursively count files in directory run the find command as follows:

find DIR_NAME -type f | wc -l

Another command that can be used to count files is tree that lists contents of directories in a tree-like format:

tree DIR_NAME

The last line of output will show the total number of files and directories listed:

15144 directories, 91311 files
