How to Find Number of Files in a Directory and Subdirectories
|
||
============================================================
|
||
|
||
In this guide, we will cover how to display the total number of files in the current working directory or any other directory and its subdirectories on a Linux system.
|
||
|
||
We will use the [find command][6] which is used to search for files in a directory hierarchy together with [wc command][7] which prints newline, word, and byte counts for each file, alternatively data read from standard input.
|
||
|
||
Following are the options that we can use with [find command][8] as follows:
|
||
|
||
1. `-type` – specifies the file type to search for, in the case above, the `f` means find all regular files.
|
||
2. `-print` – an action to print the absolute path of a file.
|
||
3. `-l` – this option prints the total number of newlines, which is equals to the total number of absolute file paths output by [find command][1].
|
||
|
||
The general syntax of find command.
|
||
|
||
```
|
||
# find . -type f -print | wc -l
|
||
$ sudo find . -type f -print | wc -l
|
||
```
|
||
|
||
Important: Use [sudo command][9] to read all files in the specified directory including those in the subdirectories with superuser privileges, in order to avoid “Permission denied” errors as in the screen shot below:

Find Number of Files in Linux
|
||
|
||
You can see that in the first command above, not all files in the current working directory are read by findcommand.
|
||
|
||
The following are extra examples to show total number of regular files in `/var/log` and `/etc` directories respectively:
|
||
|
||
```
|
||
$ sudo find /var/log/ -type f -print | wc -l
|
||
$ sudo find /etc/ -type f -print | wc -l
|
||
```
|
||
|
||
For more examples on Linux find command and wc command go through the following series of articles for additional usage options, tips and related commands:

That’s all! In case you know of any other method to display the total number of files in a directory and its subdirectories, do share it with us in the comments.
