'start' works fine with 'cmd', but it isn't an executable, so you have to run
it... through cmd again. You should be using subprocess.Popen instead of
os.system though:
args = ['cmd', '/C', 'start', 'cmd', '/K',
os.path.normpath(nuke.env['ExecutablePath'])]
if nuke.env['nukex']:
args.append('--nukex')
subprocess.Popen(args)

Subject: [Nuke-python] Launch a totally new Nuke process... From inside Nuke
Having fun trying to launch Nuke from Nuke. We have a custom Windows command
line launch system that handles all the packages, versions, licensing, etc.;
it’s based on subprocess.Popen. I’m building a tool that allows launching of a
script with a different build and/or package of Nuke. When I use the usual
culprits (subprocess.call, subprocess.Popen, os.popen, etc.) they all want to
launch a new Nuke in the same cmd window and with the same setup as the current
one – if I use any other setup it fails. So I figured I need to launch from a
new cmd window – so tried os.system(“start cmd /K blahblah”), and
os.startfile(“blahblah.bat”) which created a new cmd window – but it still has
the same problem. Of course if I use cmd directly I can launch as many
different versions of Nuke as I have licenses free. Any ideas how I can do this?
Thanks!
