The Shell ROP runs an external command, either directly or in a shell. Running a command directly does not support basic shell redirection or piping, however, it is much easier to interrupt.
Parameters
Render
Begins the render with the last render control settings.
Render Control
Opens the render control dialog to allow adjustments of the render parameters before rendering.
Render with Take
Uses the settings in a particular take while rendering. Choose Current to use the current take when rendering.
Shell
Command
The command to execute.
Execute in a Shell
Running a command in a shell allows I/O redirection and other shell features to work. However, interrupting a render in the middle of a shell command will stop the Houdini render process, but the shell command will continue until it is finished.
If off, the command will be run directly, which is much easier to interrupt. If you don’t need shell features, this is the recommended way to run external commands.
