If people use a file system as a sort of key-lookup system, this can

Just something to put behind '/'.  You can actually write
'-rf
/
'

too, and then the file in the directory "-rf\n" has a file "\n".  Note
that this, in contrast to just spaces in file names, causes damage
even when doing

find /tmp -type f|xargs rm -rf

because then you'll get calls

rm -rf -rf
rm -rf /
rm -rf
