It is possible to make autocompletion in Powershell work like in bash

autocompletepowershellscript

I love Powershell, but coming from a Linux background there is a few things that is really bugging me. Like for example how the default auto completion works.

For example: Get-PS expands to "Get-PSBreakpoint" which is the first matching command. In bash if there is only one command matching bash will expand to the matching command. If there is several hitting tab once does nothing, double tapping tab will show a list of matching commands but not expanding. Is there a way to make Powershell behave like this?

And one other thing, if i have written one line, and moves the marker back to an earlier command (marker is where the ^ is):

"Get-PSS^ | Remove-PSSession" auto completes to "Get-PSSession^", removing all trailing commands. In bash the trailing commands would still be there unaffected. Is there a way to make Powershell not remove the trailing commands when auto completing?

A bonus would be to get CTRL+L to clear the screen. CTRL+A to go to the beginning of the line, and CTRL+E to go to the end of the line.

Check out PSReadline.

From the article:

This module replaces the command line editing experience in PowerShell.exe. It provides:

  • Syntax coloring
  • Simple syntax error notification
  • A good multi-line experience (both editing and history)
  • Customizable key bindings
  • Cmd and emacs modes (neither are fully implemented yet, but both are usable)
  • Many configuration options
  • Bash style completion (optional in Cmd mode, default in Emacs mode)
  • Bash/zsh style interactive history search (CTRL-R)
  • Emacs yank/kill ring
  • PowerShell token based "word" movement and kill
  • Undo/redo
  • Automatic saving of history, including sharing history across live sessions
  • "Menu" completion (somewhat like Intellisense, select completion with arrows) via Ctrl+Space

I use it daily!
