var AclCmd = &cobra.Command{
	Use:   "acl",
	Short: "Manage access control lists",
	Long: `
DESCRIPTION

  ACLs are managed in a dedicated microservice.

  It is simpler to manage them in the frontend, but you can use this command to create/delete/search ACLs directly.
  ACLs are used to grant permissions to a given node Uuid for a given Role.

ConfigCmd represents the config command

var ConfigureCmd = &cobra.Command{
	Use:     "configure",
	Aliases: []string{"install"},
	Short:   "Setup required configurations",
	Long: `
DESCRIPTION

  Launch the configuration process of Pydio Cells.

REQUIREMENTS

  You must have an available MySQL database, along with a privileged user (for instance 'pydio').
  Supported databases are:
   - MariaDB version 10.3 and above,
   - MySQL version 5.7 and above (except 8.0.22 that has a bug preventing Cells to run correctly).

  As recommended by database documentation, tune the 'max_connections' parameter to a value in line
  with your production database server specifications. For reference, the default value of 151 will have a 
  maximum memory usage of about 575MB, but will not scale up for a multiple users load in production.

BROWSER-BASED INSTALLER

  If you are on a desktop machine, pick browser-based installation at first prompt, or you can force it with:
  $ ` + os.Args[0] + ` configure --bind default
 
  The installer opens a web page on port 8080 with a wizard for you to provide various configuration parameters, 
  including DB connection info and the login/password of the main administrator.

  In case where default port is busy, you can choose another one via the 'bind' flag, for instance:
  $ ` + os.Args[0] + ` configure --bind 0.0.0.0:12345
  or   
  $ ` + os.Args[0] + ` configure --bind <your server IP or FQDN>:12345

  After browser configuration, all microservices are started automatically and you can directly start using Cells. 
  It is yet good practice to stop the installer and restart Cells in normal mode before going live.

COMMAND-LINE INSTALLER

  If you are more a shell person, you can perform the configuration process directly using this CLI (using the '--cli' 
  flag or by choosing so at first prompt). You will then be able to choose to either use the default bindings for the 
  embedded webserver or adapt these to your specific setup.
 
  You can always reconfigure the webserver bindings afterwards by calling this command:
  $ ` + os.Args[0] + ` configure sites
  See corresponding inline documentation for further details.

AUTOMATED PROVISIONING

  For automated, non-interactive installation, you can pass a YAML or a JSON config file that contains all necessary 
  information, please refer to the documentation on https://pydio.com

ENVIRONMENT

  All the command flags documented below are mapped to their associated ENV var using upper case and CELLS_ prefix.
  For example :
  $ ` + os.Args[0] + ` configure --bind :9876
  is equivalent to 
  $ export CELLS_BIND=":9876"; ` + os.Args[0] + ` configure

  For backward compatibility reasons, the --cli, --yaml and --json  flags do not respect the above rule (this might evolve in the 3.x version).
  They are respectively equivalent to CELLS_INSTALL_CLI, CELLS_INSTALL_YAML and CELLS_INSTALL_JSON ENV vars.

var RootCmd = &cobra.Command{
	Use:   os.Args[0],
	Short: "Secure File Sharing for business",
	Long: `
DESCRIPTION

  Pydio Cells is self-hosted Document Sharing & Collaboration software for organizations that need 
  advanced sharing without security trade-offs. Cells gives you full control of your document sharing 
  environment – combining fast performance, huge file transfer sizes, granular security, and advanced 
  workflow automations in an easy-to-set-up and easy-to-support self-hosted platform.

CONFIGURE

  For the very first run, use '` + os.Args[0] + ` configure' to begin the browser-based or command-line based installation wizard. 
  Services will automatically start at the end of a browser-based installation.

RUN

  Run '$ ` + os.Args[0] + ` start' to load all services.

WORKING DIRECTORIES

  By default, application data is stored under the standard OS application dir: 
  
   - Linux: ${USER_HOME}/.config/pydio/cells
   - Darwin: ${USER_HOME}/Library/Application Support/Pydio/cells
   - Windows: ${USER_HOME}/ApplicationData/Roaming/Pydio/cells

  You can customize the storage locations with the following ENV variables: 
  
   - CELLS_WORKING_DIR: replace the whole standard application dir
   - CELLS_DATA_DIR: replace the location for storing default datasources (default CELLS_WORKING_DIR/data)
   - CELLS_LOG_DIR: replace the location for storing logs (default CELLS_WORKING_DIR/logs)
   - CELLS_SERVICES_DIR: replace location for services-specific data (default CELLS_WORKING_DIR/services) 

LOGS LEVEL

  By default, logs are outputted in console format at the Info level and appended to a CELLS_LOG_DIR/pydio.log file. You can: 
   - Change the level (debug, info, warn or error) with the --log flag
   - Output the logs in json format with --log_json=true 
   - Prevent logs from being written to a file with --log_to_file=false

  For backward compatibility:
   - The CELLS_LOGS_LEVEL environment variable still works to define the --log flag (or CELLS_LOG env var)
     but is now deprecated and will disappear in version 4.     
   - The --log=production flag still works and is equivalent to "--log=info --log_json=true --log_to_file=true"

RootCmd represents the base command when called without any subcommands

var StartCmd = &cobra.Command{
	Use:   "start",
	Short: "Start one or more services",
	Long: `
DESCRIPTION

  Start one or more services on this machine. 
  $ ` + os.Args[0] + ` start [flags] args...

  No arguments will start all services available (see 'ps' command).  
   - Select specific services with regular expressions in the additional arguments. 
   - The -t/--tags flag may limit to only a certain category of services (see usage below)
   - The -x/--exclude flag may exclude one or more services
  All these may be used in conjunction (-t, -x, regexp arguments).

REQUIREMENTS
  
  Ulimit: set a number of allowed open files greater or equal to 2048.
  For production use, a minimum of 8192 is recommended (see ulimit -n).

  Setcap: if you intend to bind the server to standard http ports (80, 443), 
  you must grant necessary permissions on cells binary with this command:
  $ sudo setcap 'cap_net_bind_service=+ep' <path to your binary>    

EXAMPLES

  1. Start all Cells services
  $ ` + os.Args[0] + ` start

  2. Start all services whose name starts with pydio.grpc
  $ ` + os.Args[0] + ` start pydio.grpc

  3. Start only services for scheduler
  $ ` + os.Args[0] + ` start --tag=scheduler

  4. Start whole plateform except the roles service
  $ ` + os.Args[0] + ` start --exclude=pydio.grpc.idm.role

ENVIRONMENT

  1. Flag mapping

  All the command flags documented below are mapped to their associated ENV var, using upper case and CELLS_ prefix.
  For example :
  $ ` + os.Args[0] + ` start --grpc_external 54545
  is equivalent to 
  $ export CELLS_GRPC_EXTERNAL=54545; ` + os.Args[0] + ` start

  2. Working Directories 

  - CELLS_WORKING_DIR: replace the whole standard application dir
  - CELLS_DATA_DIR: replace the location for storing default datasources (default CELLS_WORKING_DIR/data)
  - CELLS_LOG_DIR: replace the location for storing logs (default CELLS_WORKING_DIR/logs)
  - CELLS_SERVICES_DIR: replace location for services-specific data (default CELLS_WORKING_DIR/services)

  3. Timeouts, limits, proxies

  - CELLS_SQL_DEFAULT_CONN, CELLS_SQL_LONG_CONN: timeouts used for SQL queries. Use a golang duration (10s, 1m, etc). Defaults are respectively 30 seconds and 10 minutes.
  - CELLS_CACHES_HARD_LIMIT: maximum memory limit used by internal caches (in MB, default is 8). This is a per/cache limit, not global.
  - CELLS_UPDATE_HTTP_PROXY: if your server uses a client proxy to access outside world, this can be set to query update server.
  - HTTP_PROXY, HTTPS_PROXY, NO_PROXY: golang-specific environment variables to configure a client proxy for all external http calls.

  4. Development variables

  - CELLS_ENABLE_WIP_LANGUAGES: show partially translated languages in the UX language picker. 
  - CELLS_ENABLE_LIVEKIT: enable experimental support for video calls in the chat window, using a livekit-server.
  - CELLS_ENABLE_FORMS_DEVEL: display a basic UX form with all possible fields types in the UX (for React developers)

Functions

func Execute

func Execute()

Execute adds all child commands to the root command and sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.

func GenerateRandomBytes

func GenerateRandomBytes(n int) ([]byte, error)

GenerateRandomBytes returns securely generated random bytes. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.
