Navigating and Locating Files Using the Linux Command Line
Ready to conquer the Linux filesystem with the reliable command? Let's dive right in!
We all have those moments when we misplace a file, and comes to the rescue. It's a powerful utility that traverses the Linux directory structure to locate files and folders.
As a beginner, it's essential to familiarize yourself with test files and directories, ensuring you adhere to the instructions carefully. These tips will work on most Linux machines, including your beloved Raspberry Pi. All of the actions demonstrated here are carried out via the Terminal, which you can open on most Linux systems by pressing , , .
Hunt for a File in Linux
Let's create some sample files and a directory to demonstrate the command.
- First, create a test folder and some test files. Check the files are present using the command.
- Next, find the file named within the current working directory, using the command with the dot () indicating the search should be confined to the current directory. You should now see displayed as a result.
Discovering Files with Partial File Names
On occasion, we need to search for files with partial names. Let's look at how to do this and how searching for partial terms can impact the results.

- In the test directory, search for files containing the term "tes" in their name.
In the results, you'll see all the relevant files listed with a couple of exceptions, as the option results may be case-sensitive. In the next section, we'll explore a solution for this issue.
- Repeat the command searching for a specific file extension. To search for a particular file type (e.g., .txt), simply update the command to .
- Now let's use to achieve case-insensitive results. Using this solution, our file with the case-sensitive name TEST.f is now included in the results.
Identify Files Versus Directories
By default, the command returns both files and directories with matching results. Let's add tags to the command to isolate results for just files or directories.
- Create a new directory called within the test directory, and confirm it has been created with the command.
- Perform a command that returns both file and directory results. You should see all test files and the directory displayed as results.
- Add the tag to return only file results. Notice the directory is omitted from the results now.
- Add the tag to return only directory results. One result now should be the directory.
Scour the Entire Filesystem
In some cases, you might require a full filesystem search to locate a misplaced or forgotten file.
- ** Attempt to search for the file from the root () of the filesystem.
You'll observe that you don't have permission to search in numerous areas, which results in a long list of locations we can't search. While our file gets located, we need to sift through the report to find it. In this example, we use to enable the command to search all subdirectories.
- Repeat the previous search using to add root privileges. This pirouette provides the command with permission to access most areas within the filesystem, yielding a clearer and more navigable report. Now you'll be able to locate your files with ease!
Technology has become an essential tool for many of us, especially when dealing with files on a Linux system. With the command, you can undertake a comprehensive search for any file, even one you've misplaced. For instance, by using the option, you can search for files containing specific partial terms or file extensions, like "tes" or .
Furthermore, the command offers flexibility by allowing you to search either the current directory or the entire filesystem, as well as filter results to display only directories or files. In order to access more areas within the filesystem, you can use to run the command with root privileges, making your search more effective.
