I'd be very wary of relying on that. It doesn't account for when you are
not in the directory which contain the files your are deleting.
oracle:~/adl/tmp> for i in 1 2 3 4 5 6 7; do echo 1 > file$i; done
oracle:~/adl/tmp> touch -- -i
oracle:~/adl/tmp> rm -f *
rm: remove regular file `file1'?
oracle:~/adl/tmp> rm -f *
rm: remove regular file `file1'? n
rm: remove regular file `file2'? n
rm: remove regular file `file3'? n
rm: remove regular file `file4'? n
rm: remove regular file `file5'? n
rm: remove regular file `file6'? n
rm: remove regular file `file7'? n
oracle:~/adl/tmp> n
bash: n: command not found
oracle:~/adl/tmp> cd ..
oracle:~/adl> rm -f tmp/*
oracle:~/adl> ls -l tmp
total 0
oracle:~/adl>
