; [!bye|''bye'']
: Closes the connection to the administrator console.
; [!config|''config SERVICE'']
: Displays all valid configuration keys for the given service.

  If a key ends with the hyphen-minus character (""''-''"", U+002D), the key denotes a list value.
Keys of list elements are specified by appending a number greater than zero to the key.
; [!crlf|''crlf'']
: Toggles CRLF mode for console output.
Changes end of line sequences between Windows mode (==\\r\\n==) and non-Windows mode (==\\n==, initial value).
Often used on Windows telnet clients that otherwise scramble the output of commands.
; [!dump-index|''dump-index'']
: Displays the content of the internal search index.
; [!dump-recover|''dump-recover RECOVER'']
: Displays data about the last given recovered internal activity.

  The value for ''RECOVER'' can be obtained via the command ``stat core``, which lists all overview data about all recoveries.
; [!echo|''echo'']
: Toggles the echo mode, where each command is printed before execution.
; [!end-profile|''end-profile'']
: Stops profiling the application.
; [!env|''env'']
: Display environment values.
; [!help|''help'']
: Displays a list of all available commands.
; [!get-config|''get-config'']
: Displays current configuration data.

  ``get-config`` shows all current configuration data.

  ``get-config SERVICE`` shows only the current configuration data of the given service.

  ``get-config SERVICE KEY`` shows the current configuration data for the given service and key.
; [!header|''header'']
: Toggles the header mode, where each table is show with a header nor not.
; [!log-level|''log-level'']
: Displays or sets the [[logging level|00001004059700]] for the kernel or a service.

  ``log-level`` shows all known log level.

  ``log-level NAME`` shows log level for the given service or for the kernel.

  ``log-level NAME VALUE`` sets the log level for the given service or for the kernel.
''VALUE'' is either the name of the log level or its numerical value.
; [!metrics|''metrics'']
: Displays some values that reflect the inner workings of Zettelstore.
See [[here|https://golang.org/pkg/runtime/metrics/]] for a technical description of these values.
; [!next-config|''next-config'']
: Displays next configuration data.
It will be the current configuration, if the corresponding services is restarted.

  ``next-config`` shows all next configuration data.

  ``next-config SERVICE`` shows only the next configuration data of the given service.

  ``next-config SERVICE KEY`` shows the next configuration data for the given service and key.
; [!profile|''profile [PROFILE] [FILE]'']
: Starts to profile the software with the profile PROFILE and writes profiling data to file FILE.
If PROFILE is not given, a value ''CPU'' is assumed, which specifies to profile CPU usage.
If FILE is not given, a value ''PROFILE.prof'' will be used.

  Other values for ''PROFILE'' are: ''goroutine'', ''heap'', ''allocs'', ''threadcreate'', ''block'', and ''mutex''.
In the future, more values may be appropriate.
See the [[Go documentation|https://pkg.go.dev/runtime/pprof#Profile]] for details.

  This feature is dependent on the internal implementation language of Zettelstore, Go.
It may be removed without any further notice at any time.
In most cases, it is a tool for software developers to optimize Zettelstore's internal workings.
; [!refresh|''refresh'']
: Refresh all internal data about zettel.
; [!restart|''restart SERVICE'']
: Restart the given service and all other that depend on this.
; [!services|''services'']
: Displays s list of all available services and their current status.
; [!set-config|''set-config SERVICE KEY VALUE'']
: Sets a single configuration value for the next configuration of a given service.
It will become effective if the service is restarted.

  If the key specifies a list value, all other list values with a number greater than the given key are deleted.
You can use the special number ""0"" to delete all values.
E.g. ``set-config box box-uri-0 any_text`` will remove all values of the list __box-uri-__.
; [!shutdown|''shutdown'']
: Terminate the Zettelstore itself (and closes the connection to the administrator console).
; [!start|''start SERVICE'']
: Start the given service and all dependent services.
; [!stat|''stat SERVICE'']
: Display some statistical values for the given service.
; [!stop|''stop SERVICE'']
: Stop the given service and all other that depend on this.
