I feel very similarly, but then I'm of the mind that if I can't apt-get it, I'm not interested, and I'll bet that "open source" doesn't mean to MS what it means to the open source world. As for the NIH syndrome, one of my favorite Paul Graham essays is still "What Languages Fix" ( http://www.paulgraham.com/fix.html ) particularly for C#: the problem that C# was invented to solve is that Microsoft doesn't control Java…

That doesn't make sense. ASP.Net, .Net Core, F# are all good examples of open source projects. This announcement promises the same for Powershell: Development with the community.

What are you missing? What's the criticism?

If you want to see a broken open source project, check out Android instead..

Bash is 27 years old. It was written to replace the Bourne shell, which is 39 . It is not terribly surprising that a 9 year old tool like Powershell made some improvements over an earlier tool that was already old enough to vote!

The bash I'm running is actually 3 years old. You make it sound like bash was written 27 ago and no one has touched it since then. Secondly, what constitutes an improvement is a matter of opinion. For example, I don't see this Powersell as an improvement at all.

Autocomplete in Bash was actually a revolutionary improvement

You can use control-O for that, which does "execute this command as if I pressed enter, then when it's done bring up the following command in command line prompt". So if you have a set of commands to run that are 20 lines up in history, you can first find them (with 20x UP or by reverse-search), then just control-O control-O control-O control-O ... to execute them one after another.

Don't forget control-R. I find that even the GP's example of up arrow 20x to be ridiculous when I can type C-r and a few unique letters that were anywhere in the command to find it instantly.

Which is why any sane powershell user would probably have installed PsReadline to get this and other goodies. Preferably running in ConEmu.

As a note, there have been strongly-typed shell languages for Unix for some time. Scheme Shell[0], Turtle[1] and TCSH[2] leap to mind; but there's nothing preventing a developer from using Perl, Python, Lisp or any other language that allows itself to accept stdin as an interpreted script. 0: https://scsh.net/ 1: http://www.haskellforall.com/2015/01/use-haskell-for-shell-s... 2: http://www.tcsh.org/Welcome Edit: oh m…

lately i use nodejs and have replaced the cmd tools with node modules. It is more verbose then piping shell commands but easier to understand and the same script can be reused across platforms.

As a full-time Linux user, I have to say that bash is overrated. For instance, on Windows I could press the up arrow through my history 20x to find a group of commands I want to run, press Enter, then press DOWN for the following command, then enter, then DOWN until I run them all. In Bash, I need to press UP 20x every single time. Yes, you can customize it a lot, and you can script it but default bash isn't that spe…

Doesn't work in bash running in my Terminal.app on macOS, although it certainly does when I `ssh` into one of my Ubuntu boxes. Wonderful shortcut.

EDIT: If anyone knows an easy way to get this working on macOS, I'd love to know it.

[Disclaimer: I work for Microsoft.] As far as I recall, the original impetus behind what became PowerShell (as handed down to us in a conference room by Ballmer himself, sometime around 2001) was to fill the gap between ops people who did enterprise administration manually with tools like MMC and engineers who automated enterprise administration with tools like C++/DCOM. The latter were necessary in a lot of cases, b…

I remember writing Windows software with DCOM was difficult, but it was more on the painfulness side than a difficult intellectual endeavor. Sure you didn't need PhDs to automate things.

The part of it stuck in Windows, that is. Vendor lock-in is a powerful thing.

did you try xonsh?

I did, and i found it a pretty big chore in practice. Its two modes (shell mode and python mode), never quite knowing which one you're in, I could never quite get used to that. PowerShell doesn't have this problem, because it was designed for the command line first and for scripts second (which is, incidentally, also its major downside if you ask me).

you can force captured subprocess mode if necessary

PowerShell is my guilty pleasure of the computing world. Once you've piped strongly-typed objects around between your shell commands, text scraping seems barbaric by comparison. The problem, of course, is that you can't use all that power for much, since the pool of PS-compatible tools and utilities is much shallower than it is for Unix shells. I'm really hoping this will help spur a new wave of PowerShell-compatible…

Back in the day I thought VAX/VMS was amazing. Particularly things like file versioning, however, I had to leave it behind and do things on UNIX (and then Linux) terminals. That change was relatively painless even if I did delete a file or two that I should not have. However, I have moved on and nowadays I would not have a clue how to use VMS beyond typing 'dir'.

If the VMS 'shell' was suddenly available on Linux, despite its 'proven' benefits in various scenarios, I just would not have the working knowledge to get going with it again. Furthermore, there would be no easy answers on StackOverflow to do basic things such as recursively renaming part of all filenames, or batch modifying the content of said files.

The problem PowerShell has for me is that it might as well be a souped up version of VMS (or even BBC Basic). It is not that I am adverse to learning, it is just that I left Windows World a long time ago. Much like my move from VMS to UNIX, there were some good things that I left behind (such as the file versioning thing), however, if you move to a new way of working then there is no need for the old stuff. I appreciate that PowerShell is new, but it does not suit my way of working, i.e. cribbing answers from StackOverflow and tutorial guides.

> This is why I find PowerShell to be an answer to a question nobody asked. If bash/zsh isn't cutting it for you, drop into something like Python, Ruby or Perl to do the heavy lifting. How are Python/Ruby/Perl going to give you structured objects from "ps"? That's the promise of object-based pipes. You can get useful records out of your command-line tools without having to write an ad-hoc regex.

> How are Python/Ruby/Perl going to give you structured objects from "ps"?

The usual answer would be "by parsing /proc instead and returning meaningful objects that expose the relevant parts of the OS" but why would you want to do that when you could just output the relevant data in easy to parse XML or JSON?

Oh. My. God. Life changing! Out of curiosity, how did you discover that you could do this?

I am not the GP but I learned about C-o by reading the man page. If you spend a lot of time in Bash, why not learn to use it properly? There are less than ~100 key bindings, see "Readline Command Names" in http://linux.die.net/man/1/bash You should at the very least skim over them.
