tree man page says: -d List directories only. So the output of tree -d YOUR_TARGET_FOLDER looks like: ├── appengine_admin │ ├── media │ │ ├── images │ │ └── js │ └── templates ├── common ├── conf │ └── locale │ ├── ar │ │ └── LC_MESSAGES │ ├── bg │ │ └── LC_MESSAGES │ ├── en │ │ └── ...

Welcome to unix.stackexchange.com! There's no easy answer to your question, and far better people than me have written entire books on the subject of the Linux kernel and operating systems in general. About the scope of the project: writing an operating system is not a simple task! Even a purposefully minimal OS like Minix is a pretty complex thing! To ...

You should take a look at the Wikipedia page on benchmarking, it gives quite a few benchmark tools including the CPU ones that will work on Linux. LinPack is free but a pain to compile. But you can certainly look at NBench and some others in the list.

To be clear, I'm using criteria that are usually termed as Free Software Guidelines. The two major versions of this that exist, which are very similar to be the point of being virtually indistinguishable, are the Debian and the FSF definitions. Here is the FSF take on this. There is room for disagreement. Personally, Debian is plenty free enough for me. ...

Here's the preamble to COPYING, included with the kernel source: NOTE! This copyright does not cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does not fall under the heading of "derived work". [...] note that the only valid version of the GPL as far as the kernel is ...

Google mozilla source code 1998 found Downloading Source Archives - Mozilla Developer Network which lists a URL pattern to the Mozilla FTP server. Going by that I quickly found what appears to be the original release of the Mozilla source code, with file dates around Q2 1998.

Let me to respond to your question with a alternative answer. I guess you want read the code for the traditional Unix command line tools, not only the GNU version of these. Read the code of similar tools from different projects is a good practice for learning different ideas and implementations. GNU has a nice web interface for the repo of coreutils: http://...

If you're looking for just a simple list of directories in this directory, then you could try find . -maxdepth 1 -type d The 1 following maxdepth indicates how many levels of recursion you want. If you're looking for all directories(regardless of depth), then try find . -type d

knowledge about early source-code repositories is woefully incomplete According to the SourceForge wikipedia page: SourceForge, founded in 1999 by VA Software, was the first provider of a centralized location for free and open-source software developers to control and manage software development and offering this service for free. It's certainly the ...

Tesseract As of 2018, the best available open source OCR software is Tesseract 4 (beta) with its new LSTM neural network OCR model. Its OCR performance is much better than the previous OCR model used in version 3. Example (produce a PDF file output.pdf with a text layer for a scanned german document): $ echo page-*.png > input.list $ tesseract --oem 1 -...

Assuming you are looking for software, your best choice is probably pfSense. You could also choose m0n0wall. If you're looking for hardware, see the pfSense list list of hardware vendors. Both m0n0wall and pfSense will run on the ALIX.2D13 board.

I think the first thing you need to define is "what are the changes you wish to bring to the OS". Until you decide this, you won't really get anywhere. There is no "one path" of learning. Furthermore, I think you should define better what you mean by OS. A big part (a major part) of the Ubuntu source code is outside of Linux. Linux is only the kernel, (it ...

I don't believe either configure or make is hard to learn. However, they are complex, so they can be tricky to learn - especially through experimentation. For example, make requires commands to build a target are indented strictly with a TAB character, which is hard to distinguish from spaces in many cases. Here's a page that goes over both of those (and ...

I'm pretty sure you can use wget and SourceForge, always use the url for the latest source. http://sourceforge.net/projects/$$PROJECT_URL$$/files/latest/download?source=files Where $$PROJECT_URL$$ needs to be replace by the part of url corresponding to the project. for ntopng ==> ntop which gives you: wget http://sourceforge.net/projects/ntop/files/...

Linux is a specific software project (the kernel) that's distributed under the GPLv2. That licence requires, among other things, that the source must be provided with it derivative works created by linking the code must be distributed under the same license people be free to spread it as they please, provided the above conditions are met So if you use the ...

ZRouter.org is a FreeBSD based firmware for embedded devices, a rather new project, you'll find more information in FreeBSD's Quarterly Status Report. (It supports ARM-based devices.) Also note that the BSD magazine recently had some related articles, they covered the NanoBSD scripts using an ALIX platform, for example. (It's free to download if they get ...

As there is no central place for open source development there is no central repository containing most open source software. Some use GitHub, BitBucket, private servers, Sourceforge, Launchpad, etc. So this is a truly distributed environment and there is no immediate benefit of having one repository just copying the source. On the other hand binary ...

Fedora has among its guidelines that nothing that can't be redistributed in source without legal restrictions (in the US, mainly because it is an US based distribution) is allowed. The exceptions to this are firmware for devices that the vendor allows to distribute freely, mostly distributed by/with the kernel. This is stuff that doesn't run on your ...

The same community that brought you Ogg, FLAC, Vorbis, and now Opus, created XSPF. Unlike M3U, XSPF is XML. Unlike SMIL, XSPF is simple. Unlike ASX, XSPF is open. From a practical standpoint, however, there isn't many software out there, that supports it. I still tend to use it for little projects, etc. but aside from RockBox, VLC and I ...

A lot of it is done with autoconf. I don't have any tutorial in particular to recommend (beyond the official documentation), but you will need one and that is what you want to look for. "Autoconf" colloquially refers to a suite of tools including 'automake'. I have not done it for a while, but I'll try to sketch out the process from my notes: For each ...

This might be a bit beside the point, but if you wish the learn about the Linux kernel and start to develop it you should really look into kernel newbies. It's a site that gives you insight into the kernel mechanics (like Alexios did in an excellent way), but also let's you pick a small task to handle (being a so called kernel janitor). It's a great way to ...

There is PureDarwin: http://www.puredarwin.org/ PureDarwin is the successor of OpenDarwin, and is a free, open source, community supported project to make Darwin more usable and compatible with non-Apple hardware. In reference to this question, PureDarwin is binary compatible as long as you do not rely on a library or other feature that is only available ...

Yes and no. You could run https://www.lineageos.org/ to have a completely FOSS operating system. You would still want some sort of app marketplace. You can put "gapps" on your LineageOS phone, or you could use https://f-droid.org/. However, "thinking in the mindset of Debian," this is like running Linux on a laptop in 2001: you may still need closed-...

There are several aspects to consider... Yes, Android is open source, at least as provided by the Android Open Source Project. However as you mention more and more of the platforms’ features are provided as non-open source components, e.g. in Google Services; this includes somewhat basic features such as the swiping keyboard, and more complex subsystems ...

Each distribution tends to have its own set of tools for this, there’s not much shared software here. Debian uses wanna-build, buildd and sbuild, which you’ll all find documented on the Debian site (follow the links too). wanna-build maintains the build queue, buildd picks a package to build, and sbuild builds it. wanna-build tracks packages with missing ...

Open source means that the source is open: available to look at. That does not influence the copyright and the license. The copyright holder can of course change the license (as with DaDaBIK in June 2012). The license of the software also determines whether derivatives are allowed and can be commercial or not.

I think you're out of luck with that hardware. It doesn't have support within the OpenWRT project for it: http://wiki.openwrt.org/toh/d-link/dsl-2640u-bru-c I found no other opensource firmware project that support it either. I went through each of the project's router databases: DD-WRT Tomato Additionally I went through the larger projects and none ...
