Userconfig is a Zenwalk-specific tool to facilitate control over the user registrations on your Zenwalk system, including the defined groups, etc.
List users: lists all users on your system.
Create user: Selecting "Create user" will prompt you for the new user's name, group this user should belong to, home directory, additional group membership, and shell interpreter (usually, bash). For the account expiry date, select NEVER to make the account permanent. You'll be prompted for some additional information (suitable for multiuser systems) and the user password. When finished, the user settings are listed, with an option to edit them if some entry needs editing. Select BACK to return to the main menu. This is a GUI to the "adduser" command.
Delete users: presents you with a list of users on your system. Highlight one and press OK to delete that user. Press BACK to return to the main menu.
Change password: presents you with a list of users on your system. Highlight one and press OK to change password for that user. Press BACK to return to the main menu.
List groups: lists all groups defined on your system.
Modify group: shows a list of groups on your system. Selecting OK will allow you to modify the name for the highlighted group. Selecting BACK will send you back to the main menu.
Create group: allows you to create a new group on your system. This is suitable for example if you want to install the ClamAV antivirus programme. This programme must be given a special group name, which users are then allowed to access (if you will allow them to run ClamAV). You are prompted for the group name.
Delete groups: shows a list of groups on your system. Selecting OK will delete the highlighted group. Selecting BACK will send you back to the main menu.
About: pops the About box showing you the userconfig version you are running, etc...
