Linux Find File: A Guide to Locating Files in Linux

At its core, find is a command-line utility that allows users to search for files in a directory hierarchy based on various criteria such as name, size, modification date, and more. Its basic syntax is:

find [path...] [expression]


• [path...]: Specifies the directory to start the search from. If not provided, find defaults to the current directory.
• [expression]: Defines what to search for and can include tests, actions, and options.

Searching by Name

One of the most common use cases is searching for files by their name:

find /path/to/search -name "filename"

• Use -iname instead of -name for case-insensitive search.

Searching by Type

You can also search for items based on their type (e.g., regular files, directories):

find /path/to/search -type f

• Replace f with d to search for directories, l for symbolic links, etc.

Searching by Size

Locating files by their size is another powerful feature:

find /path/to/search -size +50M

• This command finds files larger than 50MB. Use k for kilobytes, G for gigabytes, etc.

Searching by Modification Time

If you need to find files modified within a certain time frame:

find /path/to/search -mtime -7

• This command lists files modified in the last 7 days. Use +7 to find files modified more than 7 days ago.

Executing Commands on Found Files

A potent feature of find is its ability to execute commands on the files it finds:

find /path/to/search -type f -exec chmod 755 {} \;

• This command changes the permissions of all found files to 755.

The find command is an incredibly versatile tool that can be tailored to numerous file search tasks. This is a quick guide I thought you might find useful.
