Some random scripts with no dedicated PyMOLWiki page.

Launch interactive python terminal with PyMOL process: (see also Launching From a Script)

#!/usr/bin/python2.6 -i

import sys, os

# autocompletion
import readline
import rlcompleter
readline.parse_and_bind('tab: complete')

# pymol environment

sys.path.insert(0, moddir)
os.putenv('PYMOL_PATH', os.path.join(moddir, 'pymol/pymol_path'))

# pymol launching

    if [[ -e $name ]]; then
        cd $name && $1 pull
    else
        $1 clone $2 && cd $name
