[Tutor] How to run a script file

[John Purser]

Bernard,

If you're new to Linux you might not be aware of an additional method to run
python scripts.  If the first line of your script is:
#!/usr/bin/python

And you've set your script permissions to be executable (chmod 700
myscript.py) then you can run your script just like any other program.  You
can double click on it in a GUI environment or run it from a command prompt
by just typing the script name.  Or depending on the value of $PATH variable
you might need to type "./myscript.py".  Those first characters have to be
right though.  I'm assuming your python is in /usr/bin.  And that is a hash
mark followed by an exclamation point.  This is called "hash bang" in
uningo.

Hi Bernard...

The most basic form is to type "python" followed by the script you want 
to run.  If your script is not in the system path, you'll either need to cd
to 
the directory, or give a full pathname: (the pythonpath doesn't come into 
play until the interperter is running.

python /usr/local/share/filename.py

Remember that the script will inherit whatever permissions you currently 
have, so either log in or su to the user that's expected to run the script.

Oh, and in case python itself isnt in your system path, (it probably is)  
you can find it by typing "which python" at the shell prompt.
