As I understand, apt autoremove --purge purges (as opposed to only removing) all packages eligible for autoremove.
But I cannot grasp how apt purge --autoremove would be any different. I can't think of any room for different behavior.
Are these two equivalent? Both cmds run fine:

apt purge --autoremoveis in the wrong order, as--purgeis a sub-part ofautoremove. – Logan Feb 17 '22 at 21:57man aptnot help? – waltinator Feb 17 '22 at 23:17
