Introduction:
The “find” command is a powerful tool in Linux for searching files and directories based on various criteria. It allows you to locate files based on their names, sizes, permissions, modification times, and more. 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.
1. Find Files by Name:

find /path/to/directory -name "filename"
Replace /path/to/directory with the actual directory path and "filename" with the desired file name.

To find files with a specific extension, use the command:
find /path/to/directory -name "*.extension"
Replace /path/to/directory with the directory you want to search and "*.extension" with the desired file extension.
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.
