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
