How to Find a File in Linux ▷ Command Line Examples

Easily find a file in Linux from the Terminal: If you've ever lost a file, the Linux find file command can help you track it down quickly. The Command Line Interface (CLI), also known as the terminal, allows users to interact with their Linux systems by typing commands. Learning to use the find command not only speeds up file searches but also improves your overall control over the system.

How to Find a File in Linux by Name

Here are the steps to find a file in Linux by filename:

Open a terminal. On Debian or Ubuntu, press Ctrl + Alt + T to open the terminal.
Enter the following command to search for a file by name:
```
find -name filename
```
You can also use wildcards (like *) to match variations:
```
find -name "YUMI*"
```

How the Linux Find File Command Works

The Linux find file command searches directories recursively and returns the file paths of all matches. If multiple files share the same name, all their paths will be listed. To search the entire system starting from the root directory, use:

find / -name filename

Note: This command may take time if there are many files on your system.

Search Files in Linux by Criteria

You can also refine your Linux file search using specific criteria, such as file type, size, or modification date.

Search by File Type:
```
find /path -type f
```
This searches for regular files. Use -type d to find directories.
Search by Size:
```
find / -size +100M
```
This finds files larger than 100 MB.
Search by Modification Date:
```
find / -mtime -7
```
This finds files modified within the last 7 days.

Limit Searches to Specific Directories

To narrow your search to a specific directory, replace the / with the path to that directory. For example, to search the /home/lance folder:

find /home/lance -name "YUMI*"

By limiting your search to relevant directories, you can reduce search time and get more precise results.

Execute Actions on Found Files

A powerful feature of find is the ability to perform actions on the files it finds. Here are a few examples:

Delete Files:To find and delete all .tmp files, use:
```
find /path -name "*.tmp" -exec rm {} \;
```
Warning: Use caution with rm as deletions are irreversible!

Copy Files:To copy all .conf files to a backup directory:

find /path -name "*.conf" -exec cp {} /backup/directory/ \;
