OK, here goes.

How about putting tail in the name? And I suggest:

juju tail-debug-log [--from n | --last n]

with a synonym of --all for --from 1.  Then put explicit termination instructions in the help. Although I haven’t explained from or last, you should explain carefully in the help.

(It’s only a suggestion, off the top of my head.) You could leave the old syntax/name/options in place for compatibility.

BTW, if you are visiting the help/doc, then try to explain the options better. For example:

-n, --lines  (= 10)
    output the last K lines; or use -n +K to output lines starting with the Kth

is really rather poor.  What is K??  Is 10 the default?  Why not say so explicitly?  What is the separator between the option and the value?  Is that what the equals sign is for??
