| Copy queries from one HPCC Systems host to another Using the ECL Command line interface |
| Write a script to publish multiple workunits and update ROXIE query data using packagemaps |
Using Packagemaps on the Command Line Interface (CLI) to update the dataset on an existing ROXIE query 'on-the-fly' |
| Set default values for command line parameters using an INI file (ecl.ini) Find out how to create that file, discuss the order of precedence for command line options and see some simple examples. |
| Use our scriptable command line interface to interact with your HPCC Systems environment Learn how to display a list of all queries. Then compile, publish and activate the query all in one easy step and finally confirm that it is the active query. |
