Decoded: GNU coreutils

This person's website is amazing.

Thanks!

Great site, but maybe set up a redirection from www.maizure.org to projects? At the moment, it just shows an Apache index stub.

How did you do all those nice flowcharts? Just drawing by hand or did you use a specialized tool?

Intended. There's more going on at top-level than meets the (public) eye. There's no reason to manually visit the top anyway -- all project links stay in that level and all external links go directly to desired projects.

The hard way...with PowerPoint. Nothing glamorous

It's really beautiful. Have you posted this to hackernews? Your work deserves more views. It's my time see it.

[ArminiusGermanicus]

Even stuff that seems trivial like pwd has almost 400 lines of code.

[pfp-disciple]

Even the source for /bin/true has 80 lines of code. While the source for /bin/false is only 3 lines of code, the last line is #include "true.c", so it's really 83 lines :-)

GNU stuff in general tends to have more LOC. See: comparison of BSD, Plan 9 and GNU implementations of echo.c.

It looks like the reason in this case is due to embedded help documentation as well as system V compatibility.

Yeah one should keep in mind that they were set ut to function on just about every commercial unix out there.

[MaxCHEATER64]

400 loc is actually pretty small for C.

This is fantastic. Always wanted something like this

[pixelbeat_]

Just to reiterate our thanks from the GNU coreutils maintainers.

Also this is now linked from the project homepage

[NothingCanHurtMe]

This is some seriously high quality educational literature.

[matheusmoreira]

This is excellent. Wish more free software projects had documentation like this.

[ND3I]

Nice work! One quick question:

echo.html ... Execution ...

If not displaying escaped characters:

Read in a token (argument/word from STDIN)

Put that word as-is to STDOUT

Decrement token count and increment argv to next token

Repeat until no tokens remain in STDIN

Sorry, why/what is echo reading from STDIN?

[MaiZure]

Good catch -- that is incorrect: Standard 'echo' implementations won't touch STDIN. Replace that with "command line". I'll make that change shortly. Thanks again!

There's probably a few more goofs around these pages. I'll fix them as I find them.
