[Solved] How to save a file in /usr/bin/local using gedit as an admin?

Question

In my attempt to run these two programs:
https://github.com/kerchen/export_gr2evernote
https://github.com/spiermar/bookmarks2evernote
I noticed they assumed the default python is python 2. I have python 3.3.1 and 2.6.8. I'm following the instructions at: https://wiki.archlinux.org/index.php/Py … ld_scripts
Created a file with this:
#!/bin/bash
script=`readlink -f -- "$1"`
case "$script" in
/home/Dropbox/export_gr2evernote-master1/*|/home/Dropbox/bookmarks2evernote2/*)
    exec python2 "$@"
esac
exec python3 "$@"
I then, tried to save it as p2 under /usr/local/bin/ where the only thing that's there is meteor, node, and npm, and it throws me an error saying I don't have enough permissions.
How do I save p2 as an admin in /usr/bin/local using gedit?
I've searched on the forums 'create a file in /usr/' and I haven't found anything. Can someone please help me?

I moved p2 to bin, edited my projects path with the username in front of home, saved it as python, made it executable (#sudo chmod +x /usr/local/bin/python), removed p2. Ran:

It's still referencing python 3...
"python3: can't open file 'evernote2enex.py': [Errno 2] No such file or directory"
My python file contains this:

I did everything exactly like the wiki said, what seems to be the problem?
OK. Looking at the 2 scripts you quoted, neither one is using a shbang line to set a python version to call. Without that, the python intercept doesn't even come into play. The problem that I see is the way you are starting it:
sudo nano /usr/local/bin/python
Is root really necessary for these if they are in your /home/<user>/Dropbox/ directory. And it appears that you are assuming python3 when you start them that way. If you are going to use that method and they are indeed python2 scripts, then change your command to this:
#python evernote2enex.py -m 10
You might try it as your normal user too in case root isn't really required.
I tested out the first ten with:
#python2 export2enex.py -m 10
it worked!
then proceded with
#python2 export2enex.py GStarred -n exported.enex
The script is fully functional. Thanks man!
Actually, you're not even using the script when starting your python scripts that way. You are explicitly calling either python3 (python) or python2 (python2) to run the indicated python script and not even touching the work around /usr/local/bin/python script. If your python script started with a line like either :
#!/usr/bin/env python
or:
#!/usr/bin/python
And was executable, such that you called it by it's name, i.e. "someprogram.py", then the python script in /usr/local/bin/ would take precedence and effectively intercept the python call and choose the appropriate version of python as long as the path to the directory where "someprogram.py" resides is specified in that /usr/local/bin/python script.
