Does anybody know the unix commands to add a user or group via a command line?

thanks,.

   You can use nidump to dump your own user data into a file, alter the data to fit your new user and then use niload to upload the new data to NetInfo. Alternatively, you could fill that data into the following sequence of commands:

niutil -create / /users/<username>
niutil -createprop / /users/<username> name <username>
niutil -createprop / /users/<username> uid <UID>
niutil -createprop / /users/<username> "`openssl passwd '<Password>' `"
niutil -createprop / /users/<username> home <Home>
niutil -createprop / /users/<username> shell <shell>
niutil -createprop / /users/<username> gid <GID>

It shouldn't be difficult to alter the above commands to add a group, which contains considerably less data.

Technically you have to use NetInfo. However NetInfo is a royal pain in the *ss.

I'd suggest downloading adduser and deluser for OSX. They mimic the standard utilities that come with Linux, OpenBSD and probably most other varieties of Unix.

To do it with NetInfo you do the following:

mkdir /Users/username
niutil -create . /users/username
niutil -createprop . /users/username gid 0
nituil -createprop . /users/username uid 300
niutil -createprop . /users/username shell /bin/tcsh
niutil -createprop . /users/username realname "My Name"
niutil -createprop . /users/username home /Users/username
chown -R username /Users/username
passwd username

Everyone I know obviously uses the AddUser script.
