In this article, we will explore 15 examples that demonstrate the versatility of the “find” command and how it can streamline your file management tasks.

3. Find Directories:

To search for directories instead of files, use the command:

find /path/to/directory -type d

Replace /path/to/directory with the directory you want to search.

4. Find Files by Size:

To find files based on their size, you can use the following command:

find /path/to/directory -size +10M

This example finds files larger than 10 megabytes. Adjust the size according to your requirements.

13. Find Files Using Logical Operators:

To combine multiple search criteria, use logical operators like AND (-a), OR (-o), and NOT (!). For example:

This command finds files with either a .txt or .doc extension.
