Description

This step allows you to get the value of a variable. This step can return rows or add values to input rows.

Note: You must specify the complete variable specification in the format ${variable}
or %%variable%% (as described in Variables) . That means you can also enter complete strings in the variable column, not just a variable.

For example, you can specify: ${java.io.tmpdir}/kettle/tempfile.txt and it will be expanded to /tmp/kettle/tempfile.txt on Unix-like systems.

See also the Set Variables step.
To convert the Variable into a data type other than String use Select Values - Meta Data tab.
To get system values, including command line arguments, use the Get System Info step.
