Since it overwrites my history when used in multiple terminals, I want to turn off the functionality fc -W. Unfortunately I have a habit of typing it often.

I think it's not possible to make an alias, since there is a whitespace in fc -W.

So I tried making a function, something like this:

# Make sure to never invoke fc -W
fc(){
    for x; do
        if [[ "${x}" == -W ]]; then
            echo "I'm sorry Dave. I'm afraid I can't do that."
            return
        fi
    done
    fc "${@}"
}

However, now the call fc "${@}" calls itself, and I get infinite recursion. Typically I would avoid this by using e.g. /usr/bin/fc, instead of fc, however:

$ type fc
> fc is a shell builtin

How can I avoid the infinite recursion in this case? Or is there a better way to disable one flag of a command?
