But where can I plug in a shell script? When the user types in

$ rm -rf /

and pushes the Enter key - how will I know? csh seems to have a precmd
function which the user can define and which is executed before each
command. The only thing that comes close in bash is PROMPT_COMMAND. But
that's obviously executed _after_ a command was run.
