Is there something analogous to a bashrc file for Powershell?
There is not an exact equivalent of a bashrc file in Powershell. However, Powershell does have a similar concept called a profile file. The profile file is essentially a script that is executed whenever a Powershell session is started. There are multiple profile files that can exist, depending on the scope of the session.

The locations of the profile files vary based on the version of Windows and Powershell being used. Some sample locations for profile files include:

$HOME\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1

$HOME\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

C:\Program Files\WindowsPowerShell\Modules\Microsoft.PowerShell_profile.ps1

You can create and edit a profile file using any text editor. Once created, the profile file can contain any Powershell commands or scripts that you want to run every time a Powershell session is started.
