To remove files and directories in Linux, you can use these five methods:
- To remove an individual file, navigate to its location using
cd, and delete it with
- If you want to remove an empty directory, simply use
- To remove directories and all their contents, including files and subdirectories, use
rm -r mydirectoryafter navigating to the desired location using the
cdcommand in the Terminal.
- If you want to delete multiple files and directories simultaneously, navigate to their location and execute
rm file1.txt file2.txt mydirectory.
- To delete files and directories based on patterns using wildcard characters, launch the Terminal and run
rm *.txtto remove files and directories matching the pattern.
To safely remove files and directories in Linux, verify the items you intend to delete, back up important files beforehand, and understand the permanent nature of deletion. Also, be careful when using wildcards. Apart from that, you should back up the system configuration before removing system files so that you can minimize the risk of data loss.
Explore the guide below to know the step-by-step process to efficiently remove files and directories in Linux, along with seven important precautions.
Removing files and directories in Linux is not just about tidying up your system—it’s also important for optimizing performance and freeing up storage. You can do this in the top five ways using the Linux CLI. But this process comes with its own set of risks. That’s why I’ll also highlight seven important precautions to ensure you avoid accidental deletions and lose your critical data.
How to Remove Files and Directories in Linux [5 Ways]
To remove files and directories in Linux, you can use the
rm command for individual files,
rmdir for empty directories, and
rm -r for directories and their contents. To delete multiple files or directories, simply specify their names after the
rm command. Apart from these commands, you can add wildcard characters to delete files and directories based on certain patterns. Here’s the detailed guide for each of these methods:
1. Removing Individual Files
Removing individual files in Linux is a very common and simple task. It lets you delete only a specific file without affecting other files or directories on your Linux system. To remove a specific file, you can follow these steps:
- Right-click and click the Open in Terminal option from the context menu.
- Navigate to the location where the file is located using the
- Delete the file using the
rmcommand followed with the file name:
- Next, run the
lscommand to confirm the deletion of the file from the current directory.
Remember to be careful while using the
rm command, as it permanently removes the file without any prompt for confirmation.
2. Removing Empty Directories
The purpose of removing empty directories in Linux is to clean up the file system by getting rid of directories that do not contain any files or subdirectories. It helps to maintain a well-organized directory structure by eliminating unnecessary empty directories. Removing empty directories can be done by using the
rmdir command. Here’s how you can use this command:
- Launch the Terminal and run the
lscommand to view the files:
- Next, execute the
rmdircommand, followed by the directory name that you want to delete.
rmdircommand removes only empty directories. That is, if a directory contains files or other directories, it will not be deleted. You can verify it again using the
lscommand. Your final output should look like this:
3. Removing Directories and Their Contents
To remove directories and all their contents, including files and subdirectories, you can use the
rm command with the
-r option. Follow these steps to use this method:
- Launch the command prompt and navigate to the directory using the following command.
- Execute the following command to remove directories and their content:
rm -r directoryname
- Adding the
-roption with the
rmcommand recursively removes the specified directory and its contents.
4. Removing Multiple Files and Directories
This method lets you remove multiple files and directories in Linux with a single command. It saves time and effort when dealing with large-scale file and directory deletions. Here are the steps to follow to remove multiple files and directories simultaneously in Linux:
- Enter the command line interface and navigate to the location where the files and directories are located.
- Run the following command to remove certain files or directories from your Linux system:
rm filename1.txt filename2.txt directoryname
- Once the command is executed, it will remove the specified files and directories from your Linux system.
5. Deleting Files and Directories Based on Patterns
Deleting files and directories based on patterns using wildcard characters in Linux serves the purpose of selectively removing specific types of files or directories that match a given pattern or file extension. To delete files and directories based on patterns using wildcard characters in Linux, follow these steps:
- Launch the command prompt by pressing Ctrl + Alt + T.
- Run the following command to delete files based on a certain pattern:
- The wildcard character
*matches any sequence of characters, while the .zip specifies the desired file extension. The
rmcommand with the specified pattern will delete all the files that match that pattern in the current directory.
7 Precautions When Removing Files and Directories in Linux
When removing files and directories in Linux, it’s important to take certain precautions and follow some best practices. This will let you ensure that the process is carried out accurately and safely. Here are seven precautions to keep in mind:
- 🔍 Verify the items: Double-check the names and paths of the files and directories you intend to delete. Ensure you are targeting the correct items to avoid the accidental removal of important data. You can use the
lscommand to list the files and directories in the specified location. This will help you in confirming their names and paths before the deletion.
- 💾 Backup important files: Before removing any files or directories, you should create backups of critical data. This will let you ensure that even if something is mistakenly deleted, you have a copy that can be restored. You can use the
cpcommand to create backups by copying the files or directories to a different location or storage device. Here is the complete syntax of this command:
cp -r /path/to/source /path/to/backup
- ⚠️ Understand the consequences: Deleting files and directories using the
rmcommand is permanent and cannot be undone. Ensure you fully comprehend the impact of the deletion and confirm that you no longer need the files or directories. It’s recommended to be absolutely certain before proceeding with the deletion.
- ❗️ Be cautious with wildcards: If you are using wildcards (e.g., “
?“) to match multiple files or directories, exercise caution. Ensure that the wildcard pattern matches the intended items to avoid unintentionally deleting unrelated data. You can use the
lscommand with the wildcard pattern to preview the files that will be affected before running the deletion command. This command should look like this:
- 🔑 Consider permissions: Pay attention to the file and directory permissions before attempting to remove them. Make sure you have the necessary permissions to delete the files or directories or use the appropriate commands (e.g.,
sudo) if required. You can use the
ls -l /path/to/filescommand to view the permissions of the files and directories.
- ⚠️ Test in a safe environment: If you are uncertain about the consequences of deleting specific files or directories, consider testing the removal process in a safe environment or using a test directory. This allows you to observe the results without impacting critical data. You can create a test directory using
mkdir directory_nameand perform the deletion operations on the files within that directory.
- 💾 Backup system configuration: If you remove system files or directories, ensure a system configuration backup. This helps restore the system to its previous state in case of any unintended issues occur. You can use appropriate backup tools and techniques specific to your Linux distribution to create backups of system configuration files.

Frequently Asked Questions
How can I permanently delete files and directories in Linux using tools?
To permanently delete files in Linux, you can use the
shred command. It overwrites the file’s contents before removing it, ensuring the data is securely deleted. By using this command, you can significantly reduce the chances of recovering any information from the deleted file.
Can I remove files and directories in Linux from different locations at once?
Yes, you can remove files and directories in Linux from different locations simultaneously by specifying their names or paths in a single rm command separated by spaces. Simply navigate to the parent directory, execute the rm command, and provide the names or paths of the items you want to remove. For example, running
rm file1.txt /path/to/directory2 mydirectory3 will delete
file1.txt from the current directory,
directory2 located at /path/to/, and
mydirectory3 from the current directory. However, ensure you target the correct files and directories for removal, as this operation is irreversible.
Can I recover a file or directory after removing them with rm?
Once you use the
rm command to delete a file or directory in Linux, it cannot be recovered. This is because this command is designed to remove data without any chance of retrieval permanently. When executed, the system immediately frees up the allocated space, resulting in the effective removal of the data. To prevent accidental data loss, it is crucial to back up your important files and directories regularly. In addition to that, you should double-check the items you intend to delete before using the
rm command. This will help avoid the unintended removal of critical data.
Why is it important to permanently delete files and directories?
Permanent deletion of files and directories is crucial for maintaining data security and privacy. Simply deleting files using regular methods may not completely remove the data from the storage device. By securely deleting files and directories, you can prevent unauthorized access or recovery of sensitive information, ensuring that it is permanently and irreversibly removed from your system.
