Browse questions →Know where each command runs
Opening PowerShell on your PC does not change the operating system of the server. Each example names its shell and explains the result to check.
Run on your own Windows computer in Command Prompt.
Run in PowerShell on your own Windows computer.
Connect with SSH first, then run on the Linux server.
Run on the Windows server in the stated remote session.
Example names and IP addresses are placeholders. Use the server, account, paths and port assigned to your service. Commands are text examples; copying one does not run it.
