What does the "lock account" command (ie passwd -l or equivalent) do?

passwd -l/-u : add/remove symbol '!' before password string
passwd -S : report locked password when first symbol is '!' or '*'
tested on some slackware and suse versions

about '*' prefix.
let account password contain '*' - passwd -S report locked
after passwd -l : password is '!*' - passwd -S report locked
after passwd -u : password is '*' - passwd -S report locked
again after passwd -u : no changes in account state

I dont have information for other distro.
