or by putting it in quotes, as in
$ "rm" file
in fact, if you're a shell programmer, this is a useful trick that
lets you override shell builtins with shell functions. consider
writing a "better" cd command using a function:
function _cd {
more ./.exit
"cd" $1
more ./.enter
}
alias cd=_cd
from now on, you can just type:
$ cd <dirname>
on the way out of the current directory, the function prints the
contents of an "exit file", changes directory, then prints the contents
of an "enter file", so you can set up ftp-like welcome messages on a
per-directory basis.
