Windows 95 can be set up with a weak idea of users, which can have
some of their own preferences.

This is generally considered a bad idea. You will get used to them
and assume that these commands are safe. One time you will be logged in
and the aliases will not be there for one reason or another and *poof*
there goes everything. It is a much better idea to have wrappers around
dangerous functions that you get into the habbit of using. If they
disappear or are unavailable (let's suppose you are on another system)
the worst that will happen is a command not found error.
I use the following zsh function, which could be trivially adapted to a shell
script or function in your favorite shell.
srm() {
[[ $# -gt 0 ]] || {echo "Usage: srm file [file ...]"; return 1}
for i in $*; do
if [[ -f $i ]]; then
echo $i
mv $i ~/.rm
else
echo "$i cannot be removed."
fi
done
}
