Display current users. Display user Ids only.

Display current process. Prompt the user to check all processes or a specific process. If the user selects all processes, display all process to the screen. If the user selects a specific user, display only those user processes.

Display a listing of the user’s directory and allow permission changes. Prompt the user to change filer permissions (y/n). If yes, prompt the user for the file name. Display the file’s permission. Ask the user to enter the add or remove the following permission: read the user, write user, execute user, read group, write group, execute group, read other, write other and execute other. After file permissions have been changed, display the file’s new permissions.

Display an alphabetized list of the users currently on the system.

basexserver

basexserver(1)							 The XML Database						    basexserver(1)

NAME

       basexserver - XML database system and XPath/XQuery processor (server mode)

SYNOPSIS

       basexserver [-cdeipSz] [stop]

DESCRIPTION

       basexserver starts the server mode of the native XML database system basex(1) on default port 1984.

OPTIONS

       A short description of option can be obtained from

	   $ basexserver -h

       or by browsing http://docs.basex.org/wiki/Startup_Options#BaseX_Server

USER MANAGEMENT

       On first startup a user 'admin' with default password 'admin' exists (make sure to change this)!

       Admin permissions are needed to execute one of the following processes.

       o  Creating user 'test' with password 'test':

	  > CREATE USER test test

       As global permissions valid options are 'none', 'read', 'write', 'create' and 'admin'.

       o  Revoking all global permissions from user 'test':

	  > GRANT none TO test

       Valid local permissions are 'none', 'read' and 'write'.

       o  Granting write permission on database 'factbook' to user 'test':

	   > GRANT write ON factbook TO test

       Note:  Local  permissions  overwrite  global  permissions. As a consequence, the 'test' user will only be allowed to access (i.e., read and
       write) the 'factbook' database. If no local permissions are set, the global rights are inherited.

       o  Showing global permissions:

	   > SHOW USERS

       o  Showing local permissions on database 'factbook':

	  > SHOW USERS ON factbook

       o  Dropping of user 'test':

	  > DROP USER test

       Further details on user management are to be found in the BaseX Documentation Wiki (http://docs.basex.org/wiki/User_Management).

DATABASE COMMANDS

       A list of supported Database commands can be obtained from
