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).

Drive-by armchair comment: it seems like the obvious answer would be to change the prompt depending on what mode you're in?

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. PowerShell will never accumulate a library as comprehensive as what any of those three have, each has had decades to accumulate packages of all kinds, and more are still being added. It's odd, but not surprising given their history of "N…

[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…

All those sysadmins would have been perfectly happy with just a properly working unix like shell.

I'm always in favor of things being open-sourced, but I do kind of wonder in what universe I would use PowerShell when Bash is readily available.

It is about Microsoft being a neutral player in a multiple platform world. Microsoft want people using their tools as it means they are more likely to use their platforms and services. Be it PowerShell on Linux or Bash on Windows or VSCode on macOS they want to make the best tools in the hope that it will push companies/developers towards Azure/SQL/Cloud as that is where the future for MS is. Windows is on life suppo…

>Windows is on life support and they know this.

How is Windows "on life support"? Desktop/laptop computers are not going anywhere, at least until they invent some kind of VR (and no, mobile OSes like iOS are not suitable for doing real work and managing data in a networked environment the way desktop OSes are). Windows still has at least 90% of the OS market. People and businesses could change to an alternative, but they just aren't, and they aren't going to unless something really drastic happens to force them to (and this would likely have to include many popular applications also providing support for one or more of the alternatives). In the business/enterprise world at least, there is simply no indication that Windows is in any danger at all of losing marketshare or revenue, in fact it's probably going to increase since businesses seem to love the software-as-a-service model.

MS could probably just make Windows free for home users (and make even money on them with advertising and selling telemetry data and also support calls), maybe small business users too, and then soak the big businesses with high fees for their site licenses and SaaS and other services.

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…

IIRC correctly, the major PowerShell push started with Win Server 2008, and headless server mode (no desktop). A lot of WinX sysadmins pissed their pants that they couldn't use GUI's to control everything, and PowerShell was pushed as the way to do server management w/o GUI's (crazy, I know).

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. > So, yes, someone did ask for it - the IT industry. The part of it stuck in Windows, that is. Vendor lock-in is a powerful thing.

Yeah, DCOM was a task of fillout the correct fields with the correct values, and try again until you get it right. Anyone with passing C++ knowledge could do it through shear brute force. It's one of the things which made me never want to program on Windows again.

I ported a bunch of COM to Linux in the late 1990's. Not DCOM with the full RPC, but just in-process COM. I had .so shared libs with DllMain and DllCanUnload now in them, I had CoCreateClass, I had a significant part of the registry API implemented in terms of a text file store (HKEY_LOCAL_USER being in the home directory, HKEY_LOCAL_MACHINE somewhere in /etc, ...) and such. IUnknown, QueryInterface, AddRef, Release, ...

I think I tried something like this once before, and it broke something else. I can't remember what that was, so I'm totally trying this.

Yeah, this breaks the "move over by word" with Ctrl+Left and Ctrl+Right which I use a lot. Maybe I need to add them explicitly.

Ah. I use the standard emac'esque commands to move over by word. alt+b for back word, alt+f for forward word. Not at all intuitive... windows line movement commands win over emacs bindings form an intuitive perspective.

Also you don't need these to get up/down to work:

    "\e[C": forward-char
    "\e[D": backward-char
Those are for left/right arrows.

That doesn't work on my CentOS box. [kapil@localhost ~]$ ip addr show | grep inet inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host inet 192.168.128.236/24 brd 192.168.128.255 scope global dynamic eth0 inet6 fe80::215:5dff:fe80:501/64 scope link [kapil@localhost ~]$

ip addr | awk '/inet / { print $2 }'

That doesn't work either.

  [kapil@localhost ~]$ ip addr | awk '/inet / { print $2  }'
  127.0.0.1/8
  192.168.128.236/24
  [kapil@localhost ~]$
You guys are just proving my point. _I_ already know how to do it using bash. Its just that using objects and querying properties is far simpler. And I just took a random example because its a common thing that someone would want to do.

Cool! I'm having a play with it and it seems to work really nicely. Does anyone know why the following commands don't produce the same output? get-childitem | ConvertTo-Csv get-childitem | ConvertTo-Json | ConvertFrom-Json | ConvertTo-Csv It seems like, if there's a perfect underlying data model doing what's effectively an identity conversion shouldn't change anything. Edit oooo, and all the linux stuff is available…

ls is an alias for Get-ChildItem. However, grep is the native command in this case. While such things work to some extent, it has the problem of turning your objects into plain strings. Effectively the same as if you had run

    (ls | % Name) -match '_'
The fact that the file's name is its default string conversion can be pretty annoying when dealing with results, e.g. from gci -recurse where it's quiet important to retain the path to the file. So, careful with such things. On Stack Overflow I tend to scold people who reduce PowerShell objects to strings without good reason ;-)
