Options can be specified multiple times. All options are evaluated in the given order (in earlier versions, the sequential evaluation was limited to the specified inputs, query files, queries and commands, while all other options were initially set). The standard input can be parsed by specifying a single dash ({{Code|-}}) as argument.

This article is part of the Getting Started Guide. Each BaseX Startup mode has one or more command-line options which are described in this article.

Command-line options can be specified multiple times. Please note that all options will be evaluated in the given order. The standard input can be parsed by specifying a single dash (-) as argument.

Standalone[edit]

Added with Version 11: -C, -Q, -W

The following options are available for the standalone Command-Line Client: 

$ basex -h
BaseX [Standalone]
Usage: basex [-bcdiIoqrRstuvVwxz] [input]
  [input]    XQuery or command file, or query string
  -b<args>   Bind external query variables
  -c<input>  Execute commands from file or string
  -C<file>   Execute command script file
  -d         Toggle debugging output
  -i<input>  Bind file or database to context
  -I<input>  Bind input string to context
  -o<path>   Write output to local file
  -q<expr>   Execute XQuery expression
  -Q<file>   Execute XQuery file
  -r<num>    Run query multiple times
  -R         Toggle query execution
  -s<args>   Set serialization parameters
  -t[path]   Run tests in file or directory
  -u         Toggle updates in original files
  -v         Toggle output of progress info
  -V         Toggle detailed query output
  -w         Toggle whitespace stripping
  -W         Enable indentation with whitespaces
  -x         Toggle output of query plan
  -z         Toggle output of query result

Further details are listed in the following table. If an equivalent database option exists (which can be specified via the SET command), it is listed as well. For the examples to work, it might be necessary to escape some characters depending on your operating system.

Flag Description Option Default Examples
[input] Evaluates the specified input:
  • The input string may point to an existing file. If the file suffix is .bxs, the file contents will be executed as Command Script; any other file content will be evaluated as XQuery expression.
  • Otherwise, the input string itself is evaluated as XQuery expression.
 • "doc('X')//head"
• query.xq
• commands.bxs
-b<args> Binds external variables to XQuery expressions. This flag may be specified multiple times. Variables names and their values are delimited by equality signs (=). The names may be optionally prefixed with dollar signs. If a variable uses a namespace different to the default namespace, it can be specified with the Clark Notation. BINDINGS • -bv=example "declare variable $v external; $v"
• -b{URL}ln=value
"declare namespace ns='URL'; declare variable $ns:ln external; $ns:ln"
-c<input> Executes commands. If the specified input is a valid URI or file reference, this file is evaluated as Command Script. • -c list
• -ccommands.txt
• -c"<info/>"
-C<file> Evaluates the contents of the specified file as Command Script.
-d Toggles the debugging mode. Debugging information is output to standard error. DEBUG false
-i<input> Opens the specified XML file, directory with XML files, or database. The opened input can then be processed by a command or XQuery expression. -iitems.xml "//item"
-I<input> Assigns an input string as item of type xs:untypedAtomic to the query context. -I "Hello Universe" -q "."
-o<path> All command and query output is written to the specified file. -o output.txt
-q<expr> Evaluates the specified string as XQuery expression. -q"doc('input')//head"
-Q<file> Evaluates the contents of the specified file as XQuery expression.
-r<num> Specifies how often a specified query will be evaluated. RUNS 1 -V -r10 "1"
-R Specifies if a query will be evaluated or parsed and compiled only. RUNQUERY true -V -R "1"
-s<args> Specifies parameters for serializing XQuery results; see Serialization for more details. This flag may be specified multiple times. Key and values are separated by the equality sign (=). SERIALIZER -smethod=text
-t[path] Runs all Unit tests in the specified file or directory. -t project/tests
-u Propagates updates on input files back to disk. WRITEBACK false
-v Toggles the output of process and timing information. false
-V Prints detailed query information to the standard output, including details on the compilation and profiling steps. QUERYINFO false
-w Toggles whitespace stripping of XML text nodes. By default, whitespaces will be preserved. STRIPWS false
-W Enables indentation with whitespace. By default, query results will not be indented. SERIALIZER indent=no
-x Toggles the output of the query execution plan, formatted as XML. XMLPLAN false
-z Turns the serialization of XQuery results on/off. This flag is useful if the query is profiled or analyzed. SERIALIZE true

GUI[edit]

The following options are available for the standalone Graphical User Interface: 

$ basexgui -h
BaseX [GUI]
Usage: basexgui [-d] [files]
  [files]  Open specified files
  -d  Enable debugging

You can pass one or more files as parameters. If an XML document is specified, a database instance can be created from this file. Other files are opened in the editor.

Server[edit]

Added with Version 11: -C

The following options are available for the Database Server: 

$ basexserver -h
BaseX [Server]
Usage: basexserver [-cdnpSz] [stop]
  stop       Stop running server
  -c<input>  Execute commands from file or string
  -C<file>   Execute command script file
  -d         Enable debugging output
  -n<name>   Set host the server is bound to
  -p<port>   Set server port
  -S         Start as service
  -z         Suppress logging

Details on all options are listed in the following table (equivalent database options are shown in the table as well). For the examples to work, it might be necessary to escape some characters depending on your operating system.

Flag Description Option Default Examples
stop Stops a local database server instance and quits.
-c<input> Executes commands. If the specified input is a valid URI or file reference, this file is evaluated as Command Script. -c"open database;info"
-C<file> Evaluates the contents of the specified file as Command Script.
-d Enables debugging output. Debugging information is output to standard error. DEBUG false
-n<name> Specifies the host the server will be bound to. SERVERHOST -p127.0.0.1
-p<port> Specifies the port on which the server will be addressable. SERVERPORT 1984 -p9999
-S Starts the server as service (i.e., in the background). Use YAJSW, or start BaseX as an ordinary background process to get more options.
-z Prevents the generation of log files. LOG true

Multiple -c and -i flags can be specified. All other options will be set before any other operation takes place. The specified inputs, query files, queries and commands will be subsequently evaluated after that in the given order. The standard input can be parsed by specifying a single dash (-) as argument.

Client[edit]

Added with Version 11: -C, -Q, -W

If the Database Client is launched, you will be requested for a username and password.
