In Linux, se voglio cambiare la home directory di un utente, posso usare il comando usermod:
http://linux.about.com/od/commands/l/blcmdl8_usermod.htm
usermod [-c comment] [-d home_dir [-m]] [-e expire_date] [-f inactive_time] [-g initial_group] [-G group [, ...]] [-l login_name] [-p passwd] [-s shell] [-u uid [-o]] [-L | -U] login
Esiste un comando equivalente in OS X?
