groupadd/useradd not found on Mac OSX

Solution 1:

groupadd and useradd are Linux-isms.

For some good answers on how to add users from the command line in Mac OS X, see this question on ServerFault:

Solution 2:

Like mentioned before, useradd (and adduser) are Linux commands.

Lucky for you there is the OS X dscl command. I've written a simple script for adduser and deluser that you can find at the following links. The key piece of the linked adduser script is below.

sudo dscl . -create /Users/<user>
sudo dscl . -create /Users/<user> UserShell /bin/bash
sudo dscl . -create /Users/<user> RealName "<realName>"
sudo dscl . -create /Users/<user> UniqueID "<userID>"
sudo dscl . -create /Users/<user> PrimaryGroupID <groupID>
sudo dscl . -create /Users/<user> NFSHomeDirectory /Users/<user>
sudo dscl . -passwd /Users/<user> <passwd>
sudo dscl . -append /Groups/admin GroupMembership <user>
