Use python module trace through Shebang

Question

I am working on an environment where I have to call my python script by itself : ./myscript.py instead of python-2.4 -m trace -t /myscript.py.

So , I try to add arguments in the shebang like below :

#!/usr/bin/python-2.4 -m trace -t

print "HELLO"

print "HW"

But I got the error message below :

/usr/bin/python-2.4: module trace -t not found

Is it possible in Python ? I don't want to handle this trace module inside my script.

It isn't possible to do this simply on most platforms, particularly Linux. The POSIX standard only requires that a single command line option be supported by the shebang. This can mean that the arguments are truncated, but it can also lead to all of the options being passed as a single option, as though they were contained in quotation marks.

The simplest way to achieve this is to create an additional wrapper. For example:

 #!/bin/bash
 /usr/bin/python-2.4 -m trace -t ./myscript.py
