Specifies the OpenEdge startup parameters you want to use.
output-file
Specifies the name of the file where messages are sent.
Notes
For UNIX, the BPRO command runs the following executable:
_progres -1 -b &
The & character causes an OpenEdge batch session to run in the background, and returns control to the terminal once the session starts. When the & character is not present (for example, when you simply use the (-b) startup parameter), OpenEdge initiates a batch session in the foreground without terminal interaction and control does not return to the terminal until the session completes.
On UNIX and in Windows, you can redirect batch job input and output with the < and > redirection symbols. You also can use the pipe symbol (|) to put an OpenEdge batch run in a command pipeline.
