Mastering the rm Command in Linux: How to Delete Files and Directories Safely

If you’re working on a Linux or Unix-based system, knowing how to delete files and directories using the rm command is essential. In this tutorial, we’ll explore how the rm command works, how to safely remove files and directories, and how to use its most useful options like -i, -f, -v, and -r.

Whether you’re a beginner or just need a refresher, this guide will walk you through everything you need to know about using rm.

What is the rm Command in Linux?

The rm (short for remove) command in Linux is used to delete files and directories. By default, it does not move files to the trash—they are permanently removed, so it’s important to use this command carefully.

Creating Sample Files to Test

Let’s begin by creating some test files using the touch command:

This will create four text files. Use ls to confirm the files are created.

Basic Usage of rm to Delete Files

To delete a single file:

After running this, use ls again and you’ll see that 1.txt is gone.

To delete multiple files in one go:

This command will remove all the listed files at once.

Using rm -i: Confirm Before Deleting

The -i (interactive) flag prompts you before deleting each file. This is a safety measure to prevent accidental deletions:

You’ll get a prompt:

Type y to confirm deletion or n to skip it.

Using rm -I: Confirm Before Bulk Deletion

The capital -I option is similar to -i, but it only prompts once if you’re deleting more than three files:

Prompt:

Type y to confirm all deletions.

Using rm -v: Show What’s Being Deleted

The -v (verbose) flag shows which files or directories are being deleted:

Output:

This is useful for tracking deletion in scripts or logs.

Deleting Directories Using rm -r

To delete non-empty directories, use the -r (recursive) flag:

For example, if you create nested directories:

Then delete them recursively:

This will remove a3, a2, and a1 in sequence.

Using rm -ir: Safe Recursive Deletion

Add -i to get confirmation at each step:

You’ll be prompted to confirm each directory deletion (a3, a2, and a1).

Using rm -rf: Forceful Deletion

To delete directories without any prompts (use with extreme caution):

This will delete everything inside a1 without any confirmation.

Deleting Empty Directories with rm -d

If you only want to delete an empty directory:

For verbose output:
