Hi Nico, > This breaks systems that keep "python" as python2 and don't have a "python2" > binary, no?
It would totally depend on the distro but in my experience "/usr/bin/python" and "/usr/bin/python2" are both symbolic links to the real python executables. So it works fine for many distros that only have python2.x and do not have python3 as well. E.g. on Ubuntu 12.04 LTS (Python2 is default) $ ls /usr/bin/python* /usr/bin/python /usr/bin/python2 /usr/bin/python2.7 /usr/bin/python-mkdebian dan@Sputnik:~$ ls -l /usr/bin/python* lrwxrwxrwx 1 root root 9 Jun 18 2013 /usr/bin/python -> python2.7 lrwxrwxrwx 1 root root 9 Jun 18 2013 /usr/bin/python2 -> python2.7 -rwxr-xr-x 1 root root 2989496 Sep 26 21:29 /usr/bin/python2.7 -rwxr-xr-x 1 root root 14078 Jul 12 2012 /usr/bin/python-mkdebian and similarly on Fedora 18 (python2 is default) $ ls -l /usr/bin/python* lrwxrwxrwx. 1 root root 7 Jan 22 2013 /usr/bin/python -> python2 lrwxrwxrwx. 1 root root 9 Jan 22 2013 /usr/bin/python2 -> python2.7 -rwxr-xr-x. 1 root root 7120 Aug 9 2012 /usr/bin/python2.7 -rwxr-xr-x. 1 root root 1785 Aug 9 2012 /usr/bin/python2.7-config lrwxrwxrwx. 1 root root 16 Jan 24 2013 /usr/bin/python2-config -> python2.7-config lrwxrwxrwx. 1 root root 14 Jan 24 2013 /usr/bin/python-config -> python2-config lrwxrwxrwx. 1 root root 3 Aug 1 23:06 /usr/bin/python-pip -> pip and on something like Arch Linux where Python3 is default (I also have python2.7 installed along side) $ ls /usr/bin/python* lrwxrwxrwx 1 root root 7 Nov 26 16:42 /usr/bin/python -> python3 lrwxrwxrwx 1 root root 9 Nov 26 15:53 /usr/bin/python2 -> python2.7 -rwxr-xr-x 1 root root 6224 Nov 26 15:53 /usr/bin/python2.7 -rwxr-xr-x 1 root root 1668 Nov 26 15:53 /usr/bin/python2.7-config lrwxrwxrwx 1 root root 16 Nov 26 15:53 /usr/bin/python2-config -> python2.7-config -rwxr-xr-x 1 root root 94 Aug 22 13:15 /usr/bin/python2-pyuic4 lrwxrwxrwx 1 root root 9 Nov 26 16:42 /usr/bin/python3 -> python3.3 -rwxr-xr-x 2 root root 10384 Nov 26 16:42 /usr/bin/python3.3 lrwxrwxrwx 1 root root 17 Nov 26 16:42 /usr/bin/python3.3-config -> python3.3m-config -rwxr-xr-x 2 root root 10384 Nov 26 16:42 /usr/bin/python3.3m -rwxr-xr-x 1 root root 1972 Nov 26 16:42 /usr/bin/python3.3m-config lrwxrwxrwx 1 root root 16 Nov 26 16:42 /usr/bin/python3-config -> python3.3-config lrwxrwxrwx 1 root root 14 Nov 26 16:42 /usr/bin/python-config -> python3-config The patch is fine for the Linux distros that I use but I cannot speak for everybody. Do you know anyone that uses a (still supported) distribution that does not provide the python2 symlink? I haven't talked about OSX at all... I don't use it so I can't test it but I would be surprised if it didn't work because I've written python scripts before (with the same shebang) that I know OSX users use.
