How to make PowerShell tab completion work like Bash

New versions of PowerShell include PSReadline, which can be used to do this:

Set-PSReadlineKeyHandler -Key Tab -Function Complete

To make it permanent, put this command into C:\Users\[User]\Documents\WindowsPowerShell\profile.ps1.

powershell cmd tab-completion

It is now possible to get PowerShell to do Bash-style completion, using PSReadline.

powershell cmd tab-completion

tab only completes the command name not its previous arguments/parameters.

to also autocomplete the complete command with arguments from history set the below keybinding.

Set-PSReadlineKeyHandler -Key UpArrow -Function HistorySearchBackwardSet-PSReadlineKeyHandler -Key DownArrow -Function HistorySearchForward

Now, type few characters of command name and use up/down arrow to autocomplete this command (with arguments) from history.

real time saver.
