Shell Action

For example, suppose you have a program that reads five data tables and creates a file in a specified format.

You know the program works.

Shell allows you to do portions of your work in Hop but reuse the program that reads the data tables as needed.

The Shell workflow action is platform agnostic; you can use a batch file, UNIX, and so on.

When you use a Shell workflow action, Hop makes a Java call to execute a program in a specified location.

The return status is provided by the operating system call.

For example, in batch scripting a return value of 1 indicates that the script was successful; a return value of 0 (zero) indicates that it was unsuccessful.

You can pass command line arguments and set up logging for the Shell workflow action.
