That is intended to send the script to an already running Chimera (or starts a Chimera if it finds none running).  If that is not what you are aiming for you can just use "chimera tmp.py" or 'chimera --script "tmp.py 1.5 100"' if your script wants some arguments.  If you really are trying to send the script to an already running Chimera, report a bug using Chimera menu Help / Report a Bug… in Chimera (non-headless version) and explain that the problem is with the linux headless version.
