Create users on FreeBSD Systems with useradd

Hello FreeBSD Geeks.

As you may know, on FreeBSD Systems you have to invoke the pw command to run the generical useradd command.

Syntax: pw useradd [options] user

This is the most usefull useradd command, from my point of view:

This creates the user anakin, with /home/starwars as homedir and bash as the user’s default shell.

-m is for creating the homedir if it doesn’t exist and copy the data from the /etc/skel folder in the freshly new created dir. if the folder already exists, nothing will be copied from the /etc/skel dir. -d is for setting the home directory, -c is for adding a comment about the user and -s is for choosing the login shell.

# pw useradd -m -d /home/starwars -c "the anakin user" -s /usr/local/bin/bash anakin

Other useradd usefull arguments:

  • -u UID : create the user with the specified user id.
  • -U : create a group with the user’s name and add the user to the group
  • -g : specify the group ID (GID) or group name in which the user will be included.
  • -o : allow this user to have a non unique UID

To set the password for the user, use the passwd command and type the password twice:

# passwd user
