Inspired by “Leon Bambrick” blog, I’ve decided to start a Category on my blog wherein I’ll be posting small stuff that I learn that never get a chance to land up on a blog post. It can be a Tip, single line of code or concept, anything that is worth sharing.

Leon is a great guy! (Follow him on twitter @SecretGeek) . I was going through some of his work on his blog and Quickly became fan of his inclination towards learning and implementing new things.

TODAY I LEARNED :  How to identify PowerShell variables in a script open Powershell ISE ?

For a small code its a piece of cake, but to identify all variables in hundreds of lines of code is Humongous task.

Well it was easy than I expected, use the Powershell parser to tokenize (A programming token is the basic component of source code, like variables, operators and separators)all content of the current open tab of ISE, then filter out variables. BOOM! here you go with the variables.

PowerShell variables

I’ve wrapped this in a function and added functionality to identify variables in all open ISE.

You can find the function on my Github Repository – http://github.com/PrateekKumarSingh/Today.I.Learned

Book follows a comparative method to jump start readers journey in Python, but who is the target audience? and who should read this book –

  • Any System Administrator who want to step into Development or Programming roles, and even if you don’t want to be a developer, knowledge of another scripting language will make your skill set more robust.
  • Python Developers who want to learn PowerShell scripting and understand its ease of user and importance to manage any platform.

Python is one of the top programming languages and in fast changing IT scenarios to DevOps and Cloud to the future – Data ScienceArtificial Intelligence (AI) and Machine Learning Python is a must know.

But this PowerShell Scripting guide to Python would be very helpful for you if you already have some knowledge of PowerShell
