We use the Gnome Terminal terminal emulator for this recipe, and tab completion on PowerShell on Linux on Gnome Terminal behaves exactly the same way that it works on Bash on Gnome Terminal:

• If only one word matches the string before the tab, the word is completed.
• If multiple words match the string before the tab, all possible options are listed.

If you are using VS Code for this recipe, or a different terminal emulator, its behaviour may be different.
