Your Powershell profile is a .ps1 (Powershell script) that’s automatically run whenever you start a new Powershell command prompt. You can do all sorts of customisation but possibly the best use for it is to add functions you’ve created yourself so they’re available at the command line. This post shows how to create it.
First, you need to make sure the profile script exists. Type the following into Powershell;
$profile
This will return the full path to your profile file. You can then create new one by entering;
notepad $profile
Note that if the parent folder doesn’t already exist you may get an error. You can then create the parent path manually or try the following command;
New-Item -path $profile -type file -force
This creates a new file using the full path and forces the creation of parent folders if they don’t exist. You can then edit it with notepad as above.
I normally put functions in here to speed up logging onto Office 365 or Azure plus some handy helper functions I’ve written, but there’s all sorts of cool stuff you can do (see Technet for some examples).
