The document discusses the author's experience switching from Cygwin to using PowerShell (Posh) natively on Windows in 2010. It describes issues they initially had with Posh such as lack of emacs-like key bindings and broken aliases. It then summarizes solutions and tools the author developed to improve the Posh shell experience, including PSReadLine for readline functionality, psenv for managing environment variables, removing broken aliases, using the ConEmu console emulator, and creating custom modules for directory bookmarks and environment switching based on the current directory.

1. How did I get to live in posh?

3. (in 2010)
I switched from cygwin to PowerShell (posh).
I changed my mind.
Real Programmers DON'T USE cygwin.
(#｀Д´)ﾉﾉ┻┻;:'､·ﾞ

4. broken fork
peer performance
native exe compatibility
and more

5. (WSL)
At that time, it was not there.
orz....

6. Posh is too bad for interactive shell comparison to
bash.
No emacs-like key bindings.
Too much poor completion.
Long command name
Broken alias. Example: curl, diff

7. Many many applications append own path into
PATH environment.
The Problem is not caused by Posh, it's by
Windows.
However it is critical for console favorite people.
I call this "PATH Hell". It is something like DLL Hell

8. PSReadLine
psenv
remove-alias -force
ConEmu
cd bookmark (homemade)
ps envdir (homemade)

9. A bash inspired readline implementation for
PowerShell.
Extreamly superb cmdlet. I have no life without
this. Something like beer.
Now PowerShell 5.0 bundle PSReadLine. Good Job!
Set-PSReadlineOption -EditMode Emacs

10. Environment variables management cmdlet. For
avoid conflict.
For ex. In my default console dosen't include any
VisualStudio PATH. After start posh, execute
following command for set VS environment.
When I want vs 2017.
use vs140
use vs150

11. I made PR for Tab completion in Feb.
In this case, I use posh .
TabExpansion is powerfull.
use vs<tab>
vs110 vs120 vs140 vs150 vs90
TabExpansion

12. Just remove broken alias in
Microsoft.PowerShell_profile.ps1.
Make my life happy.
Remove-Item -Path alias:curl -ErrorAction SilentlyContinue -Force
Remove-Item -Path alias:diff -ErrorAction SilentlyContinue -Force

13. Windows console emulator with tabs.
I use evryday. I love it. <3 <3 <3

14. I made directory bookmark cmdlet to save my time.
Easy to install from
bookmark directory.
change bookmarked directory. cdb is alias of set-
cdbookmark
PowerShell Gallery
Install-Module cdbookmark
add-cdbookmark -name foo -value c:homefoo
cdb foo

15. I made environment switcher for the PowerShell.
It's add environment variable which depend on
directory.
Easy to install from PowerShell Gallery
Start new posh session and cd demo then execute
".psenvrc"
posh-direnv
cd demo
Edit-DirEnvRc
