Observations on writing to Screen and File in PowerShell

Posted on December 13, 2015 by Øyvind Kallstad in PowerShell

When writing a PowerShell script, you are typically doing “something” with “something” and getting a result based on this “doing”.

This is all well and good, but after you have gotten your result what do you do with the data? Two common scenarios are writing the result either to the screen or to a file. If the script is doing a lot of calculations, it’s quite common to also give the user some kind of feedback while it’s working, to indicate that it’s actually doing what it’s suppose to do and that it haven’t stalled.

Pro tip: Choosing the best collection for the job

Posted on November 18, 2015 by Øyvind Kallstad in PowerShell

You need to store a collection of data of some sort, so you stuff it in an array, problem solved, right? But is an array the best solution for your script? And should you care? (more…)

Progress Bar and Seconds Remaining

Posted on November 17, 2015 by Øyvind Kallstad in PowerShell

In my last post about using progress bars in PowerShell, we went through the basic usage, as well as nesting of progress bars. There was however one parameter that I didn’t discuss, and that I seldom see used; the SecondsRemaining parameter. (more…)

Quick tip: Enums with FlagsAttribute

Posted on November 11, 2015November 11, 2015 by Øyvind Kallstad in PowerShell

If you have worked with PowerShell for a while, chances are you are familiar with Enums. If you have also worked with more traditional programming languages you definitely are familiar with Enums!

Enums can have custom attributes, and one such attribute is the topic this quick tip; the FlagsAttribute! (more…)

ConvertTo-UNCPath

Posted on October 26, 2015October 26, 2015 by Øyvind Kallstad in PowerShell

Converting a path to UNC path doesn’t really take that many lines of code, but having recently been in a project where I needed to do this a lot, I got tired of copy-pasting the same 2-3 lines of code back and forth, and decided to create a helper function out of it. (more…)

Change the PowerShell console size and state programmatically

Posted on October 11, 2015October 11, 2015 by Øyvind Kallstad in PowerShell

Being able to change the size of the console window (or any window for that matter) are quick and easy to do using the mouse. The same for changing the window state (for example maximizing a window). But if you want to do this programmatically (for whatever reason) it’s not so simple.

I have created a small function that makes this much easier to accomplish. (more…)

Test-PasswordStrength

Posted on September 24, 2015September 24, 2015 by Øyvind Kallstad in PowerShell

In my last post I showed you a function to generate secure and complex passwords. This time I have written a small function you can use to test password strength similar to the strength bar you sometimes see in password fields on websites.

New-Password

Posted on September 19, 2015September 23, 2015 by Øyvind Kallstad in PowerShell

There is an ocean of password generators out there, and even quite a few written in PowerShell, but there were some features I wanted in a password generator that made me create my own. (more…)

PowerShell Prime

Posted on September 18, 2015September 18, 2015 by Øyvind Kallstad in PowerShell

Prime numbers will always have a special place in every mathematicians (or cryptographers) heart. The usefulness for the standard PowerShell user is questionable, but just for the fun of it I have created/translated a couple of functions for working with Primes.
