You can build output by running the ant command and specifying the DITA-OT parameters at the command prompt. You also can use an Ant build script to provide the DITA-OT parameters

1. Run the startcmd file that is applicable for your operating system.
   The startcmd.bat and startcmd.sh files are in the directory where you installed the DITA-OT.
2. To provide the DITA-OT parameters from the command prompt, issue the following command:

   ant -Dargs.input=input-file -Dtranstype=transformation-type -Dparameter-name=value

   where:

   • input-file is the DITA map or DITA file that you want to process.
   • transformation-type is the transformation type.
   • parameter-name is the name of an optional parameter.
   • value is an applicable value for the optional parameter.
   If you do not specify an output directory, by default, the DITA-OT writes the output to the installation-directory\out directory.
3. If you use a build script, issue the following command:

   ant -f build-script target

   where:

   • build-script is name of the Ant build script.
   • target is an optional switch that specifies the name of the Ant target that you want to run. If you do not specify a target, the value of the @default attribute for the Ant project is used.
