rm
-f, --force ignore nonexistent files, never prompt
-i prompt before every removal
-I prompt once before removing more than three files, or
when removing recursively. Less intrusive than -i,
while still giving protection against most mistakes
--interactive[=WHEN] prompt according to WHEN: never, once (-I), or
always (-i). Without WHEN, prompt always
--one-file-system when removing a hierarchy recursively, skip any
directory that is on a file system different from
that of the corresponding command line argument
--no-preserve-root do not treat `/' specially
--preserve-root do not remove `/' (default)
-r, -R, --recursive remove directories and their contents recursively
-v, --verbose explain what is being done
--help display this help and exit
--version output version information and exit
By default, rm does not remove directories. Use the --recursive (-r or -R)
option to remove each listed directory, too, along with all of its contents.
