rm Command

The rm command is used to delete a file or directory.

Syntax

rm [OPTION]... [FILE]...

  • -i: Prompt for confirmation before deleting each file.
  • -I: Prompt once before deleting more than three files or when deleting recursively, fewer prompts than -i but still prevents most mistakes.
  • --interactive[=WHEN]: Prompt according to WHEN, never, once with -I, or always with -i, if no WHEN is given, always prompt.
  • --one-file-system: When recursively deleting a directory, skip any directory on a filesystem that has a different corresponding command line parameter.
  • --no-preserve-root: Do not treat / specially.
  • --preserve-root: Do not remove /, default option.
  • -r, -R, --recursive: Recursively delete directories and their contents.
  • -d, --dir: Remove empty directories.
