Deleting files and directories is usually easy with Finder for Mac users. While graphical interface works great most of the times, using terminal commands usually offers more flexibility and power. In this article we'll learn various methods to delete files and directories on macOS using the command line.

How to Delete a File in Mac
Using the rm command
The most common way to delete a file in Mac's terminal is using the rm (remove) command:
rm filename
Replace filename with the name of the file you want to delete. If the file is write-protected or you don't have sufficient permissions, you may need to use sudo:
sudo rm filename
Securely deleting files
macOS provides a built-in command for securely deleting files, which is similar to the shred command in Linux:
rm -P filename
The -P flag overwrites the file with zeroes three times before deleting it, making it much harder to recover.
How to Delete a Directory in Mac
Using the rmdir command
To delete an empty directory, use the rmdir command:
rmdir directory_name
Using the rm command
To delete a directory and all its contents, use the rm command with the -r (recursive) option:
rm -r directory_name
Be very careful with this command, as it will delete the directory and everything inside it without asking for confirmation.
Dealing with Locked Files
If you encounter a "Operation not permitted" error when trying to delete a file, it may be locked. To unlock and delete it:
- First, remove the "locked" flag:
chflags nouchg filename
- Then delete the file:
rm filename
Handling Hidden Files
Hidden files in macOS start with a dot (.). To delete a hidden file or directory, you can use the same rm commands, but you'll need to either:
- Type the full name including the dot (you can use tab to autocomplete):
rm .hidden_file
- To see hidden files in the current directory before deleting:
ls -a
Additional Tips and Considerations
Use caution: The rm command deletes files permanently. Unlike moving files to the Trash, this action is typically irreversible.
Use the -i flag for confirmation: Add -i to rm commands to prompt for confirmation before each deletion:
rm -i filename
- Wildcard deletion: You can use wildcards to delete multiple files. For example, to delete all .txt files:
rm *.txt
- Deleting files with special characters: If a filename contains spaces or special characters, enclose it in quotes:
rm "file with spaces.txt"
- File recovery: While it's possible to recover deleted files using third-party software, it's not guaranteed. Always have backups of important data.
Conclusion
Understanding how to delete files and directories using Mac terminal commands gives you more control over your system. Remember to always double-check before deleting, especially when using powerful commands like rm -r. With practice, you'll become more comfortable managing your files efficiently from the command line.
Remember, with great power comes great responsibility. Sometimes you can't undo so always ensure you have backups of important data, and be cautious when using deletion commands, especially with sudo privileges.
