You can teach your linux system that executable python files must be executed with /usr/bin/python. This allows you to write python scripts without the shebang line
#!/usr/bin/env python . This snippet shows you how to do it !
# This is rather a shell code snippet than a python code snippet :) # Your linux system can recognize that an executable file # with extension ".py" must be executed with the python interpreter. # For this, issue the following command in a terminal (as root): echo ':Python:E::py::/usr/bin/python:' > /proc/sys/fs/binfmt_misc/register # Now test this: echo "print dir()" > mytest.py # create a python script in the current dir chmod +x mytest.py # make it executable ./mytest.py # run it # You dont need the shebang line '#!/usr/bin/env python' # in your scripts any more !!!!! # Now we don't want to do this each time we log in. We can # edit (as root) a file named rc.local. It can be /etc/rc.local # on your system. On mine this file is a symbolic # link and the true file is /etc/rc.d/rc.local. Anyway, # we add the following lines at the beginning of this file if [ -e /proc/sys/fs/binfmt_misc ]; then echo ':Python:E::py::/usr/bin/python:' > /proc/sys/fs/binfmt_misc/register fi # Now your system knows that ".py" files must be interpreted # with /usr/bin/python.
