How to Remove Files on Terminal

Managing files on your computer is an essential skill, especially if you’re a frequent user of the terminal. Removing unnecessary files can help free up space, improve performance, and keep your system organized. In this guide, I’ll walk you through the process of deleting files using the terminal on various operating systems.

Understanding File Deletion

Before diving into the commands, it’s important to understand the difference between deleting and removing files. When you delete a file, it’s moved to the trash or recycling bin, where it can be restored if needed. However, when you remove a file, it’s permanently deleted from the system, and the space it occupied can be reused.

Using the rm Command

The most commonly used command for deleting files is `rm`. Here’s how to use it:

1. Open your terminal.
2. Use the `cd` command to navigate to the directory containing the file you want to delete.
3. Type `rm filename` and press Enter. Replace “filename” with the actual name of the file.

For example, if you want to delete a file named “example.txt” in the current directory, you would type:

rm example.txt

Be cautious when using the `rm` command, as it permanently deletes files. To avoid accidental deletions, you can use the `-i` flag, which prompts you for confirmation before deleting each file:

rm -i filename

Removing Multiple Files

If you need to delete multiple files, you can use wildcards. Wildcards are characters that represent one or more unknown characters. Here are some common wildcards:

For example, to delete all files ending with “.txt”, you would type:

rm .txt

Removing Directories

Deleting directories is similar to deleting files, but you need to use the `rm` command with the `-r` or `–recursive` flag. This flag tells the command to delete the directory and all its contents:

1. Open your terminal.
2. Use the `cd` command to navigate to the directory containing the directory you want to delete.
3. Type `rm -r directoryname` and press Enter. Replace “directoryname” with the actual name of the directory.

For example, to delete a directory named “example”, you would type:

rm -r example

Using the shred Command

Deleting files is only the first step in ensuring they’re completely removed from your system. The `shred` command overwrites the file’s contents multiple times, making it much harder to recover the data:

1. Open your terminal.
2. Use the `cd` command to navigate to the directory containing the file you want to delete.
3. Type `shred -u filename` and press Enter. Replace “filename” with the actual name of the file.

For example, to securely delete a file named “example.txt”, you would type:

shred -u example.txt

Using the rm Command with the –interactive Flag

The `–interactive` flag allows you to delete files one at a time, giving you the opportunity to confirm each deletion:

1. Open your terminal.
2. Use the `cd` command to navigate to the directory containing the file you want to delete.
3. Type `rm –interactive filename` and press Enter. Replace “filename” with the actual name of the file.

For example, to delete a file named “example.txt” with the interactive flag, you would type:

rm --interactive example.txt
