The story of installing PowerShell7

I installed PowerShell7 on my Windows 10 PC.

Install to

Since the shortcut “PowerShell 7” was created in the start menu, check the location and name of the executable file in the properties.

"C:Program FilesPowerShell7pwsh.exe" -WorkingDirectory ~

The file name of the executable file is pwsh.exe. Version 5.1 of PowerShell was a PowerShell .exe, so there seems to be no inconvenience in calling both.

Launch PowerShell7

Press the “Win” key and type “pwsh” to start it with the enter key. Similarly, when you type “powershell” and press the enter key, PowerShell 5.1 was confirmed.

Output and encoding of text files

echo "日本語" | Out-File sample.txt

When I opened it with Notepad, I was able to confirm that the encoding was UTF8 and there was no BOM.

Check the cmdlet alias that is being set

I only touched it a little, but it seems that the basic operation can be handled by knowledge of PowerShell 5.1.

The object returned by Invoke-WebRequest did not have a ParsedHtml property. I think that it can not be helped, because it seems to be derived from IE, but it is a pity because I expected it to be supported in PowerShell 7. (Do you want to study RPA?)
