Unless they are managing tons of 'nix boxes, why not just stick with powershell?
Because BASH was there a decade before PowerShell and is way easier to use. Easier than CMD, too. More power, less effort. Why wouldn't they have been using it? CSH has long been available on Windows, too.

Do people confuse all the things that don't have GUIs as being part of PowerShell?
No, they confuse them as part of CMD.
You mean you think Windows admins actually think like chkdsk is part of CMD and not an application of its own?
I'll admit that I've conflated this a bit by mixing windows users and windows admins in this conversation. But super green admins - who don't know powershell, only ever seen CMD - yeah, I think they could be confused about that.
So you think it is improving because now they are seeing two shells and realizing that now, with three shells to use (the GUI is a shell) that the apps aren't tied to the shell?
Did they never notice that they were apps on the disk that could be deleted?

This has long been a "strength" of Linux, because BASH wasn't universal (nothing was) and because BASH is available on loads of things that are not Linux (like VMware ESXi, Solaris, Windows, etc.) it's super obvious with even casual use to see that top or whatever can't be part of BASH because you can run them without BASH and BASH can exist without them.
Because Linux has long has like ten shells in typical installations, it's really hard to confuse the shell and the apps that it calls. Windows only shipped with one traditionally, making it a lot harder to figure out.

I'll admit my own ignorance in this a while ago - just because you saw different apps on the disk didn't mean they were truly separate - there are a few dozen exe's in the Office folder - yet all those things are tied together. Granted word.exe doesn't need excel.exe, but (I think at least) there are common exe's that they both call as part of their usage. So that leads one to believe this is a common practice and since all those other things in windows are in the same directory as CMD, why aren't they just part of it?

DLLs are shared, EXEs generally are not. BASH is certainly a single file. As is AWK. As is PowerShell. As is Python. As is top. It's very, very rare for EXEs to be shared like libraries. In Windows, typical libraries are called DLLs. In Linux, they are typically .so

Without looking at a box with them, I'm guessing you are thinking of the launcher application, which is definitely separate. That .exe is like a shell, sort of, with the only job to discover and launch other applications. It then launches Word, Excel, or whatever else is there. Each being completely separate applications.
In that case, the "shared" is misleading as it is its own thing, and the underlying things are not connected at the application level. You can remove the launcher without disabling anything that it calls. Or remove Word without affecting the launcher or Excel.

I could be mistaken about word.exe calling other exes versus just calling DLLs. but to the uninitiated, all being in the same folder makes them seem like they are a single thing, and even though they are multiple files, they seem inexorably linked. I'm not saying it's right to think that - only that they do, I know I did in the past.

Now, when taking this bit of the conversation and looping it back to careers, this is where we could say how important it is that IT people learn basic programming. Because it takes extremely little time programming, like a few days, before we can then simply explain that "BASH is a programming language" to make basically everything else really clear. Realizing that BASH is a programming language, it becomes obvious that things like top, AWK or cal (the calendar) are obviously applications being called from it, and not a part of it.
No programming language or shell anywhere has that stuff built in. For some bizarre reason, BASH has earned this weird reputation as being the cumulation of all software that can be run by an operating system.
But oddly, why does AWK or cal get confused as part of BASH, but not Rocket, MySQL, Microsoft SQL Server and other apps called identically?
Because the people teaching it don't know jack or **** about the OS they're teaching. Our intro to UNIX professor probably did, but I doubt anyone else knew, or cared back in 1996.

@travisdh1 It's funny, in all these years I feel like I've come across so few good teachers. but I feel like my UNIX professor in 1994 was spot on, and he wasn't even an admin, just a programmer. But I learned so much admin stuff from him.

I've been investing my time in learning Ansible and SaltStack to manage Linux and Windows. And started using the native tools available from Linux and Windows through Ansible and SaltStack.
