Add something automatically to the end of bash command

Question

I would like to know how to add something to the end of a specific bash command without having to type it out explicitly.

For example, I would like to be able to type:

$ mycommand argument

and the line will be submitted as:

$ mycommand argument &

I know how to set up an alias in my .bashrc (e.g. alias command="command -i") which will let me add non-positional arguments but I can't figure out how add something to the end.

Answer 1

Define a shell function.

mycommand () {
  command mycommand "$@" &
}
