Microsoft is projecting that the .NET ecosystem will become a main revenue driver, regardless of the underlying operating system.

Microsoft operates as though, and under the assumption that their software is needed. It's a faulty premise. The presumption is arrogance incarnate.

As a business I can fully, completely operate without any of the their software, profitably, peaceably, and with at least the same amount of friction or less. And more securely.

If you think otherwise, you are ignorant of the tools available for free and of some intelligently thought-out engineering.

Quality of a language is such a trite, over-used discussion that the results/goals of software are completely forgotten. This too is arrogant ignorance.

How many software engineers are there in the world? It's more than taxi-cab drivers. More than Dr.'s More than teachers. Cooks, farmers, and builders (not combined of course). This is evidence of software for software's sake. There is no quality. Just a moving shell-game of "you need this".

I love writing algorithms--that PowerShell and .NET are some kind of something that will solve people's problems any better than something else is simply marketing. I have a pet rock to sell you.

For Fedora 24 users: So some reason, the rpm that Microsoft provides doesn't list all the dependencies that it actually requires. What is even worse, the compiled binaries inside, require quite outdated versions of icu & openssl that are not available in Fedora 24 any more. What I've come up w/ to force poweshell to run: # dnf install icu lldb lldb-devel lttng-tools lttng-ust To view what we're still missing: $ find…

The build scripts for PowerShell right now require an existing powershell binary to work. If I can untangle this and work out what's required to build from scratch, then that'll probably help you build a proper Fedora RPM.

(I'm looking into it for Debian, but the work will help other distros, too).

getting an IP is still pretty ugly, somehow: ip address show dev eno1|grep 'inet '|cut '-d ' -f6 But I wouldn't call it unreliable. The cut is the only really nasty bit. Changing your fstab is easy with a little awk: $2=="/tmp"{$4=$4 ",nosuid"} {print $0} Given, it won't remove contradicting options...

And either the "ip" command can never change how it formats its output, or your script with that command will break some day.

...Which is why I said it was ugly. The grep probably won't break, the cut is more likely to. This is in part because the 'ip' command isn't very well designed. A better solution I found is

  ip addr show wlan0 | grep -Po 'inet \K[\d.]+'
Which is less likely to break. If your system supports it,

  hostname -I
Works great. However, this seems to be an ubuntuism, and it doesn't work on my system.

As a Windows Sysadmin, my life would be a living hell without PowerShell.

I don't see a tremendous amount of accumulated wisdom in Powershell. It may be newer, but I'm not sure they looked at prior art or had design members who were shell gurus in any other shell than `cmd.exe`, which is a horrific shell. Why are commands horrendously long in powershell? If you spend time in the shell, you don't want your fingers falling off due to overuse. Aside... one of the design decisions Microsoft to…

There are lots of aliases for cmdlets for exactly this reason - interactive use. The verbose commands are useful when reading a script that isn't working at 3am in the morning when your boss is breathing down your neck to fix it "stat!". RE - your aside '\' vs '/' - I think most of us still shake our head at that decision. Jeffrey Snover [MSFT]

I don't know if that was really a "decision" or an unfortunate compromise. DOS inherited /foo style command line parameters from CP/M, and DOS 1 didn't have a hierarchical file system, so there was no conflict with the path delimiter character UNIX was using. When DOS 2 introduced directories (and brought over the cd, md, rd, etc. commands from UNIX) suddenly we had to choose between massively breaking backwards compatibility or using something else, like \, as a delimiter.

Having lived around the Windows world since Win 3.1, I cannot get over the sneaking suspicion that somewhere deep down Microsoft is working towards an attempt to "embrace and extend" Linux. Maybe it's just me, but they've gotten rather interested in Linux lately and they are reaching out to it in seemly innocuous ways. I hope I am wrong.

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…

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…

I just now have the chance to use Powershell on Linux, with that Powershell command you demonstrated, I get a command not found.
