as a non-root user, this would be fine.
but, i was setting up a docker container for development [1], and upon
running a login shell, the shortcuts script would get invoked,
and would remove /dev/null (and later re-create it), which changes its
type from a character device into a regular file, thus breaking the
system (e.g. apt update wouldn't work anymore).
