Powershell Configuration

$PROFILE

# Create the file if it does not already exist
if (-Not (Test-Path -Path $PROFILE -PathType Leaf)){
    New-Item -ItemType File -Path $PROFILE -Force
}
# Note: The -Force flag will create the directories if needed, but will overwrite existing files

Keep in mind that Powershell may use different $PROFILE files for different versions or contexts - for example, on Windows, for Powershell Core, it's located at $HOME\Documents\PowerShell\Microsoft.PowerShell_profile.ps1, or either $HOME\Documents\WindowsPowerShell\Profile.ps1 or $HOME\My Documents\WindowsPowerShell\Profile.ps1 for Windows Powershell. The version of Powershell that runs within VSCode and VSCodium would be $HOME\Documents\PowerShell\Microsoft.VSCode_profile.ps1.

To edit the profile, you can open it with your text editor of choice. In my case, I'd start a Powershell session with the pwsh command, and run vim $PROFILE.
