Bash: get TAB completion as a list

I would like to know a way to get a list of possible command completions, but without executing it. For example, to get a list of Linux modules that can be loaded, you can do:

$ sudo modprobe [TAB][TAB]
... list of completions

But what if you want to "save" this list in a file? I think that for this purpose there should be any command parameter complete:

$ complete <whanever option> modprobe > modprobe-completion-list.txt

or, for partial improvements:

$ complete <whanever options> "modprobe i2" > modules-prefix-i2-list.txt
