Revision as of 15:01, 12 November 2019
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
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 -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 -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 chopping -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:
|
• "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
|

GUI
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.

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 -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.
