the rm command on linux to permanently remove files
The rm command removes files and directories. To use:
rm filename
or
rm -r folder
On myth, this will prompt you for each file to remove. If you want to remove the files without a prompt, you need to type
rm -rf directoryName
But be careful -- you need to ensure that you know exactly what you are removing, because the rm command will attempt to remove any path, and with the -rf flag, it will recursively do so.
