Hi, it's probably a very noob question but i cannot find a proper documentation online.
I'd like to run a simulation on Linux and save the output files and the log in specific folders.

I created a dop and i was able to run the simulation (and save the outputs) using GUI buttons in Houdini.
How can i reproduce all this via command line?

Here's my command line

/opt/hfs18.0.499/bin/hbatch /home/ciara/Documents/Houdini_test/myscene.hipnc

Thanks for the help

You can use the same command-line:

hbatch /home/ciara/Documents/Houdini_test/myscene.hipnc

To see all the switches, just do:

hbatch --help

You have to send commands to hbatch, either by piping a command file or using -c on the command line.

e.g.

$:/hip> hbatch test.hip -c "render /out/geometry1 -f 1 20; quit;"
hbatch Version 18.0.460 (Compiled on May  8 2020)

Rendering geometry1
$:/hip>

hbatch is just houdini without an interface. Look at the help for hscript for how to script a non-gui session. There's also hython if you prefer to script in python.
