Seriously? If you think Xcode is "great dev tools", then you need to get out more.

(and I think the UI overhaul in [Xcode] 4.0 was a major step backwards).

I feel like XCode used to be *better* dev tools. Honestly, I was most fond of medium-early versions of CodeWarrior (before OS X, before OS 9, really; the early "pro" versions), though that may be nostalgia talking more than accurate recollection. XCode, like everything else, seems to have bloated and gotten creaky with age (and I think the UI overhaul in 4.0 was a major step backwards).

I can't stand Xcode 4, it seems to have been written by someone who doesn't understand IDEs. I'd sooner use Eclipse. I could barely tolerate 2.x. For that matter, Objective-C drives me crazy. I use CodeWarrior 7 for Classilla and frankly there's no Mac development tool that even comes close. The debugger is delightful, if "debugger" and "delightful" can ever occur in the same utterance, and it integrates well with MPW and all the other build tools that Jobs II Apple swept out. The programs I create on OS X all compile from the command line. If I absolutely have to use Xcode to build something, it's with xcodebuild, not with GUI Xcode.

Well, /strictly/, yes, but since I have never seen or heard of a single UNIX or Linux shell that does what I consider to be the sane or right thing, I think it's fair to say that it's an attribute of the OS as a whole.

I think writing a small program to do what would take a single command on almost any other CLI OS I have ever used illustrates my point rather well...!

Joking aside, I have considered it. I honestly think a decent Win9x/NT-style DOS shell for Linux would help its adoption by Windows techies moving across. The main snag being that C21 Windows techies barely use the CLI at all and are not really skilled in it, whereas 1990s or even 1980s MS techies probably know Unix already. I did start, in the early 1990s, a COMMAND-COM compatible shell for Acorn RISC OS. Its native CLI is deeply odd, as it dates back to the late '70s/early '80s and owes nothing to anything - it was all original. (Examples: directories are called Catalogues and are listed with CAT; their names are separated in paths with dots, rooted at filesystemname::devicenumber:$.; there are no native file extensions but when needed they are simulated with slashes, so an MS-DOS file called C:\DOS\COUNTRY.SYS would be something like dosfs::4:$.DOS.COUNTRY/SYS (allowing for ::0 to ::3 being 4 floppy drives). It was... weird.) I only got as far as DIR, COPY, DEL and TREE and got distracted and moved on. But I'd love a DOS shell for Linux, yes. If I had the skills, I'd try to do it.

For manipulating DOS floppies, or for running DOS apps. But they are, obviously, *not shells.* So, no, I do not use them for attempting to manipulate Unix files. Look, Unix/Linux has replaceable shells and comes with a choice of them: bash, zsh, tcsh, csh, etc. etc. This is well-known. What I am arguing for is another one, but one that uses a CLI that is approximately syntax-compatible with that of the industry-leading OS, the OS that runs on approximately 95% of the desktop, laptop and server computers in the world and has done for 25y now. I know that this CLI is less powerful and less flexible and less capable than the Unix one. I am not arguing that. What I am arguing is that the Unix one is hard work. It's complex, it takes time to learn - and, I'd say, a certain mindset, too - and it's also quite dangerous if you're not careful. It is, as all these "rm *. o" examples illustrate, very easy to accidentally do things you didn't mean to because it's so terse and the commands can do so much. It can do many brilliant and wonderful things that I don't want to do. :?) But it is often notably poor at /easily/ and /simply/ doing the stuff I do on a daily or weekly basis, like, say, searching recursively through users' home directories, finding, moving then later erasing all the temporary files abandoned by MS Office because it's too crap to clean up its own detritus after itself or even keep its temp files in the designate temp-files directory. If I can specify *.foo as the source of a command then I damned well want to specify *.foo as the /destination/ of a command as well. I do not /care/ about how the shell is implemented, I want it to work in a simple and obvious fashion. If *.foo matches all files called (something)(full stop)('foo') in one position in the command then it is natural and obvious that it should /also/ match (something)(full stop)('foo') in /any other position in the command as well/. It does on almost every other CLI OS I have ever seen, from RSTS to VMS to CP/M to DOS to Windows 7. /Pace/ different wildcard operators and things it does on AmigaOS and Acorn RISC OS and so on as well. On every Unix shell I've seen (i.e. since the late 1980s), it doesn't. Because Unix doesn't work that way. It's special. It does things differently. Well, that's fine. I am not arguing for the removal of all other shells except my notional DOS-like one. Good gods no. I'm just saying that, for all its limitations, the DOS-type method does actually have its uses and indeed its *benefits*. I honestly think it's easier - easier to learn, easier to use. And given that DOS-type systems run on 95% of x86 hardware, and that most people in IT only use DOS-type x86 systems and know nothing else, then there's a fairly strong case to be made that this way works and is good enough. Perhaps it's another instance of the "worse is better" argument. http://en.wikipedia.org/wiki/Worse_is_better I'm not saying it's crap. I'm saying it's more difficult, yes. Ah, but none of those sell roughly ten times more than all the Unixes in the world ever put together, do they? None of those utterly dominate commercial, charitable and governmental computing. None of those are the de facto standard, so overwhelming that even the surviving RISC UNIX boxes today use the buses and the interface connectors and the video and networking standards, and the storage media, and the disks and the RAM, *set by the x86 PC.* Sure, if that's what you want, fine. Users? Yes, in large part. Admins? No, actually, that is changing, fast. Modern versions of MS server tools are graphical wrappers around command lines, and when you perform an operation, they show you the command line first so that you can learn to do it yourself. The big new thing in Windows servers is the massive engineering effort to separate out the kernel and the GUI, the server application layers from the presentation layers. There are now CLI-only versions of Windows Server (although they retain the windowing system, thus far), and CLI-only versions of the big server apps, so that you can run them on headless boxes hosted in VMs and manage them remotely. Yes, it means MS is trying hard to catch up with where Unix has been for decades, yes yes. We know. But still, it's happening. Finally, MS is learning some stuff from the way things are done on the older OSs, the ones in long trousers that were established before Tim Paterson even wrote QDOS. Nope. But I've done it myself. :?) Oh, yes, absolutely. But they're happy with their GUIs; leave them to it. I'm talking about a tool to make life easy for the legions of Windows techies out there to adapt to the proliferation of free Unixes. Well, a bit. That's just a thought experiment.

Joking aside, I have considered it. I honestly think a decent Win9x/NT-style DOS shell for Linux would help its adoption by Windows techies moving across. The main snag being that C21 Windows techies barely use the CLI at all and are not really skilled in it, whereas 1990s or even 1980s MS techies probably know Unix already.

(I am aware of 'file', but that doesn't, to me, do what you're suggesting.)

UNIX /does/ have and use and even depends upon file extensions, and yet, the shell does not really understand them as a separate entity from the file's /name/... & it is poorer than the admittedly far less powerful or capable Microsoft shell at manipulating

files /by extension/ a opposed to /by name/. When I do "ren *.log *.log.old" I am manipulating a /collection/ of files by their shared /extension/ and *not* by their name. No UNIX shell I am aware of can do this. Sure, you can kludge around it with loops or scripts or little Perl programs but that is more effort, more work and I would argue less elegant.

How do you think an unix shell is starting an excecutable file and trough wich mechanism it knows what todo with an perl script, an shell script, an C-shell scipt, and different kinds of executable binary formats? It looks in the file for its header and is starting the correct command interpreter for running that file or set up the environment for executing a binary executable.

In unix a shell is doing this,

Yes, the shell is doing this trough the system calls.

[...] but the system call is not using any naming conventions of file extensions to do this.

Oh man. Could you please take a look to the print filters in the printing system? This again has nothing todo wit unix as such.

In MS-DOS,

As for print filters, I hvae yet to find any documented option that allows me to tell it whether I want to print a particular piece of text as text or as PostScript code. (Because the content is exactly identical, it cannot even in principle tell on its own.) I haven't run into this problem on more than a half-dozen systems, though; I don't print very much, and even less on systems other than my own. But the details of the issue are not my point; my point is that the content is not always enough to tell.

There's no corresponding mechanism in traditional non-GUI Unix (GUIs usually add one). Yes, that more-or-less happens in those cases (GUIs and executables run from shell). But it *doesn't* happen elsewhere in Unix (e.g. for non-executable files). --T > >This is exactly what the /etc/magic mechanism is doing. > >Regards, > >Holm

Extensions are extensions. All the above is just interpretation. File association is not rocket science (though it's been reinvented too many times). The interesting exception is classic MacOS with its type/creator codes independent of extension (and where extensions were initially absent, though like Unix, supported as part of the file name).

On 12/12/11 5:23 AM, Liam Proven wrote: How does that show that representing extensions as part of a file name string is problematic? Extensions have 2 functions in Unix: ?* aide-memoire for the user including a large set of conventions; ?* (later) compatibility with legacy systems. The representation that Unix uses is effective for these use cases. Can you give an actual example of where Unix handles extensions "very poorly"? (Your faux-DOS command doesn't seem to qualify, as it is neither about Unix (rather, shell), nor a valid use of mv.) In the case of the web, browsers are supposed to pay attention to Content-Type, not sniff by extension. (Yes, I know Apache can be configured to sniff extensions. Again, this works just fine with Unix' representation.) Extensions are extensions. All the above is just interpretation.

Classic Mac OS had binary preference files, but half the time they could be easily modified with ResEdit, and with very few exceptions, most applications could at least handle having their preference files deleted as basically performing a "factory reset". We had a procedure for that at the Mac Shop. We could almost always

I'm not sure what your point is here. that's the intended design.

since when? and why not? Most of us have no problem with this.

you switch back and forth between how the GUI handles files and how the shell handles files,which one are you actually having a problem with? the GUI can easily distinguish between x.foo and x.bar named files.then again, so can the shell. a file extension is not a file "type"extensions as file types is a human fallacy, not a machine limitation.I regularly use files without any type of extension at all, quite easily. also, which shell are we talking about? c-shell? korn shell? bash? zsh?some shells have "extensions" that can differentiate files based on what's after the dot,some refer to the system configurations on what those files are.some don't care what a file is called or what it's "extension" is. the last type is the most correct, what comes after the dot is not truly an "extension"it's just part of the file name, and should be treated as such. the days of the 8 dot 3 file naming and typing conventions are long gone.

The GUI is for people who don't know how to use a computer.These people should also be forced to use "driverless-cars"

*sigh* OK, here's where Dan and I part company. I use a GUI all the time. Sometimes it's the best/easiest way to do something when I don't want to have to deal with (remembering) the intricacies of a particular feature/function. However, a poorly implemented/thought out GUI is the devil's spawn and can make a CLI a much better alternative. The alternative is also true, you can have CLIs that are so complex that tracking all of the options can be a job in and of itself. Sometimes a GUI wrapper can make those cases much easier to deal with.

It's even more general than that. Many folks have fallen into the Microsoft (FAT) limitation that a file is [3-letter extension format]

In other words: this mental model of a 3-letter file extension was around LONG before Microsoft.

Perhaps it's just me, but I really quite /liked/ the VMS system: name.extension;version. Saved my bacon a few times, did file versioning. Given how cheap disk space is now, I'm saddened it's not made a comeback.
