genius! :) maybe a cronjob? (every 24 hours overwrite the script) (silly one) maybe a startup overwrite? or an aur package?

Lots of python scripts still use #!/usr/bin/python instead of explicitly stating which version of python to use. Here's quick trick to make running various python version 2 or 3 scripts easier:
remove the /usr/bin/python symlink and replace with this shell script:
#!/usr/bin/env bash exec /usr/bin/"${PYTHON:-python3}" "$@"
Now you can set the PYTHON environment variable to be either python2 or python3, depending on which version of python the script expects. Just don't set PYTHON=python, or you'll get a recursive loop! The only problem with this approach is that /usr/bin/python is owned by the python package, so if you upgrade the python package it might create problems. Any one know of some way to work around this problem?
