The "." specifies the local machine and "-create" is the verb which directs the command. dscl . -create /Users/username UserShell /bin/bash # sets the default shell for said user dscl . -create /Users/username Realname "user name" # the alternative name used optionally by OSX to log in dscl . -create /Users/username UniqueID 503 # set a unique number id for the user dscl . -create /Users/username PrimaryGroupID 1000 # sets the primary group id. In OSX the admin groups are usually either administrator or staff. dscl . -create /Users/username NFSHomeDirectory /Local/Users/username # sets the user's home directory dscl . -passwd /Users/username password # sets the user's password dscl . -append /Groups/admin GroupMembership username
As a note, to list all available groups and their ids, you can type
dscacheutil -q group
