I want to map :bd to :bd! using:

command! -nargs=* -complete=buffer bd :call bd!

but vim told me "User defined commands must start with an uppercase letter"

---

update solutions from answer:

cnoremap bd bd!

another way

cnoreabbrev <expr> bd getcmdtype() == ":" && getcmdline() == 'bd' ? 'bd!' : 'bd'
