Adding your own command to PowerShell

Step 1: Check the profile location

under PowerShell, type $PROFILE to get the location. It usually shows something like C:\Users\username\...\WindowsPowerShell\Microsoft.PowerShell_profile.ps1.

Step 2: Edit that file to add your own command.

For example, you installed a software Typora and want to add command typora to open it. In the profile file, just add set-alias typora "{$YourSoftwareLocation}\Typora\Typora.exe". After that, you need to close and open PowerShell again. Then you can use typora to open Typora or even use it edit a file.
