The Bash shell provides a builtin command that allows you to test the exit status of a command to determine if the command was successful or not. The test command provides a way to make decisions about what will happen next in a script.

The Bash shell has a builtin test command that can be used to check for multiple aspects in a script. This exercise helps you build a script that checks to see if a file exists and if it does, checks to see if it is writable.

Testing Load with smtp-source and top
In order to evaluate the load on your box you can run smtp-source and combine that with snapshots of top to evaluate the load on the server. Now open two terminals and in one run the smtp-source command and in the other snapshots for top.

This is a "newbie" mistake, but these little details do tend to get in the way, which is why I'm posting my wee Python tutorial. If you know Python or programming, even reasonably well, this will probably seem way too simple to you. Just giving you a "heads up" so you don't waste your time. I encountered a lesson that teaches storing conditionals using booleans. The code was presented like this:..

This is a topic that is quite easy and doesn't need much explanation but still many people manage to mess it up. Not going into a hyperbole, I'll get straight to the point...Basically, given any random number, if you take its modulus with a, you will obviously get a number between 0 and a -1. This is all fine and dandy, so now someone asks you to generate a random number between a and b (a < b).

The Bash shell contains builtin commands that do not create a fork when they are used. This is a list and description of those builtins.

This article asks what the Python frameworks do when they introspect a test module to discover what tests live inside of it. It also looks at details like how common test setup and teardown is supported, or not supported, by Zope, py.test and nose. Learn how these testing frameworks will support your Python development.
