Execute a process

Description

You can use the Execute a process transform to execute a shell script on the host where a workflow will run.

The transform is similar to the workflow action Shell, but can be used in a pipeline to execute for every row.

Options

Option	Description
Transform name	Name of the transform; this name has to be unique in a single pipeline
Process field	The field name in the data stream that defines the process to start (shell script / batch file to start). Arguments can also be used.
Fail if not success	Checking this option means if the exit status is different than zero the transform fails. You can use error handling to get these rows.
Output line delimiter	Without defining a line delimiter, all returned lines are collapsed into a single string with no line delimiters. This option is available since 5.0 and by default empty for backward compatibility. You can set to any line delimiter and special characters can be set with the format $[value], e.g. $[0D] for CR or $[0D,0A] for CR/LF (since 5.0).
Result fieldname	Specify here the name of the result fieldname (STRING) added to the output stream of the pipeline. This field is populated by the output stream (stdout) of the process.
Error fieldname	Specify here the name of the error fieldname (STRING) added to the output stream of the pipeline. This field is filled by the error stream (stderr) of the process.
Exit value	Specify here the name of the exit fieldname (INTEGER) added to the output stream of the pipeline. This field is filled by the exit output of the process.
