Java seemed to have a lot more options for deployments and monitoring for a long time. More advanced 3rd party libraries in general. It had simply been around longer and thus had those tools available. Now that C# has been standard for a while almost all of those tools have a C# equivalent. As a .NET dev I'd actually argue that the things available to C# now are actually better (especially Visual Studio), but that's…

VS was probably always a better coding and debugging environment. I've used VS as far back as VS 2010 and it's always been great for C#, but I've never had more than a mediocre experience writing Java in an IDE. Did anything support VS's level of convenient debugging ability for Java?

I have not used VS as much as I have used Java IDEs, but I'd say they are on par. VS shines in how well the debugger is integrated with the rest of the environment, but both NetBeans and IDEA offer very close to the same level of convenience. Admittedly, I have never liked the Eclipse debugger.

Is this really so useful in practice? I have never used PowerShell before (nor do I have plans to do so in the near future), but I would imagine the downside is complexity, both for user and especially for developers. With text you just read and parse, while with objects you need to know the object type, its fields,... Whatever happend, I hope text stays here (and I have a bad feeling about it ever since I met system…

Pipe anything to Get-Member. For example: (ls)[0] | gm will list every field and its type on a File object. Wicked easy.

You can even just do

    ls|gm
and get the lists for both FileInfo and DirectoryInfo. There will be no duplicate types listed because Get-Member already sees to that there won't.

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.

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…

You can use Ctrl+R for reverse search. However, these are minor things... You can find a plugins and what-not to add these kind of functionalities.

I use oh-my-zsh and I'm more accustomed with searching sub-history of commands, e.g. nmap #=> shows flags...

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…

> Once you've piped strongly-typed objects around between your shell commands, text scraping seems barbaric by comparison This is why Powershell is a great thing on Windows. Windows works with .Net objects and Powershell works directly with those objects. It's also why I don't see the reason to be excited that it can run on OS X and Linux now, because neither of those systems work by passing .Net objects around. You…

> Windows works with .Net objects and Powershell works directly with those objects.

I'd say COM, WMI, and the registry are more prominent parts of Windows itself than .NET is. However, PowerShell seamlessly works with those as well.

Could you elaborate on what the actual complexity is, rather than what you imagine? For a developer writing a tool, exposing an interface as objects is far easier than having to constantly serialize data into a string. Keep in mind that once you serialize data into a string, you can never change the order of the data or else other tools will break. Not so with a object based interface. In other system-admin type task…

> Could you elaborate on what the actual complexity is, rather than what you imagine?

I can only use this feature by using a .NET language. I can't take the strongly typed objects into a Node.js script, or a perl script.

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…

I've been loving using Node.js for scripts. You get all the NPM goodies plus STDIO, and they end up working just as well as shell scripts.

One of the big advantages IMO is that I only need to master one language for all of my needs, from browser to server to shell :)

Powershell is the first language where I managed to save time by writing a program for a task. Needless to say, I'm thrilled at the prospect of using it on Linux. The only thing that I hope they will need to work on is startup time making sure it performs well on low-spec servers (It can be a bit slow starting cold on older laptops). ls -Recurse | ? { $_.Name -match ".+docx" }

I am not sure what your example does. How does it differ from find . -name " .docx" ls -Recurse | ? { $_.Name -match ".+docx" } And, if these are the same, why type in twice as many characters as a command? Actually, ls -R | grep "\.docx$" is, I think, closer in spirit. Now, the issue is things further in the pipeline, I imagine. The find solution allows selection on type name, type, date, depth, mounts, properties,…

I should have made it clear that this wasn't an example of Powershell being superior to bash, just what I can remember from that little script.

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…

or Lua?

This might come across as a little rude, but I really wish Windows developers stayed away from Unix. I moved away from Windows a long time ago because I didn't want anything to do with Windows or Microsoft, and I went to great lengths to avoid their software and their proprietary file formats. Now we had command-line interfaces, desktop environments, running on top of an incredible, powerful Unix-like OS. It was free…

I have to agree. I can only feel like this is pollution or another EEE attempt.

Tell me how well EEE works with an optional application released on Github with an MIT license will work.
