删除资源 (rm)

To delete files and directories in the terminal, use the command:

rm [path]

This command stands for Remove.

[!WARNING] Unlike files deleted via a graphical user interface (desktop), files deleted in the terminal with rm do not go to the trash bin. They are deleted instantly and permanently. Use it with extreme caution!

Deleting Files

To delete a single file in the current directory:

rm notes.txt

Deleting Directories Recursively with -r

If you try to delete a directory using just rm, the terminal will display an error stating that the target is a directory. To remove a directory and all files and subdirectories within it, you must specify the -r (recursive) option:

rm -r folder_to_delete

Forcing Removal with -f

Sometimes you may get confirmation prompts asking if you really want to delete write-protected files, or errors if a file does not exist. The -f (force) option forces deletion without asking for confirmation and ignores non-existent files:

rm -rf folder_to_delete

The combined -rf option is one of the most powerful and feared commands in the command line: it deletes everything instantly with no warnings.

Usage Examples and Common Errors

If you try to delete a directory without specifying the recursive -r option, the rm command will fail with an error:

rm backup
# Output:
# rm: cannot remove 'backup': Is a directory

To remove multiple files in a single command, list them one after another separated by spaces:

rm file1.txt file2.txt
