Problems compiling python

[Florian Lindner]

Hello,
I want to compile that small python script:

bastet:/ # cat test.py
#!/usr/bin/python
import sys, os
username = os.getlogin()
print username
os.spawnv(os.P_ WAIT, "/root/mailboxmgm.py", sys.argv)

Python 2.3.2 (#1, Oct 12 2003, 14:27:24)
[GCC 3.2] on linux2
Type "help", "copyright" , "credits" or "license" for more information.[color=blue][color=green][color=darkred]
>>> import py_compile
>>> py_compile.comp ile("test.py")
>>>[/color][/color][/color]
bastet:/ # chmod u+x test.pyc
bastet:/ # ./test.pyc
../test.pyc: line 1: syntax error near unexpected token `;'
'/test.pyc: line 1: `;ò
bastet:/ #

What is wrong?

Thanks,
Florian

A compiled Python file (.pyc) is not an executable. (Specifically, in
the Unix world, it does not contain a bangpath.) Instead, just pass it
as an argument to the Python interpreter:

max@oxygen:~/tmp% cat > hello.py
print "Hello, world!"
^D
max@oxygen:~/tmp% python

>>> import py_compile
>>> py_compile.comp ile('hello.py')
>>> ^D[/color][/color][/color]
max@oxygen:~/tmp% ls hello.py*
hello.py hello.pyc
max@oxygen:~/tmp% rm hello.py
max@oxygen:~/tmp% python hello.pyc
Hello, world!

Can I run these scripts under another UID than the user executing them?
(SUID)

Thx,
