We all have to have a setuid and setgid to be able to do things with setattr. If a python script is executed from a script that has a setuid and setgid, the executed script will be owned by the script that created it.
It turns out that we can use setattr to change values in our shell scripts and use them as variables in our scripts that don’t have setuid and setgid.
I was surprised to find that setattr doesn’t actually need to be called setattr. It just has to be called setattr. It’s also the same thing with python scripts. All you have to do is use the “setattr” function and it’ll take effect. And of course the good thing about this is that you can use your shell scripts to set variables that you will use in your python scripts. It also lets you use your shell scripts as functions too.
For more information on how to run your python scripts with setattr check out my guide to using setattr.
So what does this mean? Well if you run setattr, then all your variables in your shell scripts will be available in your python scripts. I’m pretty sure that means you can use any variables you want to in your scripts, no matter how they are set. I mean, if you’re programming in Bash and you use a function, then you can put your values in, and you can use them anywhere they are available.
I guess this is the first time in my life I have ever seen a python script that doesn’t have the line “if __name__ == ‘__main__’:” in it.
Setattr is the Python function that returns a reference to a named variable of the same name. It is also the main function that is called by all other functions in Python. Most people don’t use setattr since they are usually done as a part of initialization code or global definitions. However, it is useful to know that you can use your variables in your scripts, and you can use them anywhere they are available.
Setattr is helpful for a couple of reasons. First, you can use a variable anywhere in your code. The most common use is in a function that you call in your main script, or in a global definition (notably, in the global namespace).
Setattr is also useful for allowing you to change variables that are not in your script’s scope. In our example, it would allow us to change the name of a variable, but not the value. Other examples of setattr are functions and class variables. However, the following is a more specific example of setattr.
When we create a variable, we’re creating a new variable. The key part is that we’re assigning a value to that variable. In our example, we’re assigning the name “color” to “red.” However, what we’re really doing is defining a variable named “color” in the global namespace of our script.
