I don't know what the Cinnamon guys renamed gnome-shell when they forked, so you'll have to find this out. It's probably either cinnamon-shell or cinnamon or something. I'll assume it's called cinnamon.
Now, the GNOME Shell - and by extension, Cinnamon - will respond to SIGHUP by completely rein...
@strugee - ***emacs*** The community of emacs editing enthusiasts was adamant that the full emacs editor not be included in the base documents because they were concerned that an attempt to standardize this very powerful environment would encourage vendors to ship versions conforming strictly to the standard, but lacking the extensibility required by the community. The author of the original emacs program also expressed his desire to omit the program. Furthermore, there were a number of historical UNIX systems that did not include emacs, or included it without supporting it, but there were …
If so comments are getting out of hand and I wanted to make sure I understood this correctly:
declare is the bash equivalent of ksh's typeset. bash, zsh also support typeset so in that regard, typeset is more portable. export -p is POSIX, but it doesn't take any argument and its output is shell dependent (though it's well specified for POSIX shells, so for instance when bash or ksh is called as sh). Remember to quote your variables; using the split+glob operator here doesn't make sense. — Stéphane Chazelas19 hours ago
Do I rightly gather that the only bonus would be for shells other that bash/zsh? I don't have much experience testing that so I only tested my code in those two shells (and denoted it as such) but I can swap out declare for typeset if it's a net gain and makes it work on other shells.
@Caleb typeset is from ksh, but I don't think ksh has a typeset -g. ksh93 is now opensource (since around 2000) so you should be able to experiment with it.
Gilles already has the export -p covered though I don't think it would be useful to the OP. Anyway POSIX only specifies scalar variables, and serialising those by hand should be relatively easy (adding the quoting with awk for instance).
@StéphaneChazelas I think I'll skip it. I'm not sure on whether to keep or ditch the last section on keeping the data in a single file. It's broken and warning or not I think it might be better to ditch it rather than encourage the use of broken code --- unless there is a way out of that mess.
@Braiam - I think its a manual bug. Most of those commands can be used several ways - but most of those ways are via standard-in - like via the http-shell or pacmd. So it works fine like echo ... -10 | pacmd but needs the extra shell safety of the -- so it doesn't get interpreted as an option on the command line.
@Gilles I admit that I very consciously sometimes post (solid) assumptions on the assumption that if they are wrong, people are more likely to call this out ("This is wrong") than act on their own initiative ("Here's my answer"). That may not make for the best answer, but (casual estimate) it is a correct answer 95% of the time. The more in-depth answers in this particular scored lower because they were posted much later. I don't at all like the fact that S.E. encourages quicker...
...vs. more in-depth answers, but that is very clearly the case.
@terdon I think it's more noticeable on S.O., where the first sufficient (correct == sufficient) tends to collect all the points then the volume of viewers falls off rapidly. I think that is sort of inevitable, as opposed to indicating a moral failure of the participants, lol. Meaning, I agree we do do better, but probably mostly because we have a much lower volume (vs. being much better people). Systems involve trade-offs. The positive side of this is it entourages people to provide
a quick sufficient answer if they don't have time to get in-depth.
Punishing people for being correct but not in-depth would simply discourage answers.
True. I've just found that, in general, in depth answers do rise to the top here. On the flipside, very simple answers to silly little questions get way too many upvotes.
The uname utility gets its information from the uname() system call. It populates a struct like this (see man 2 uname):
struct utsname {
char sysname[]; /* Operating system name (e.g., "Linux") */
char nodename[]; /* Name within "some implementation-defined
...
I don't see how I possibly deserve any down votes, but there are some late answers there that definitely deserve up votes. Note that none of them is explicit about how to actually change the value, they just pinpoint its origin further.
@terdon BTW I don't think my assumption that if someone answers wrong, "people are more likely to call this out...than act on their own initiative" indicates a moral failing either. It just makes more sense. It is more important to correct what's wrong!
@goldilocks Well first of all before I even read the answers involved let me suggest that you might be thinking about votes all the wrong way. Not all "downvotes" are because an answer is inherently bad.
The vote system is first and formost a crowd-sourced way to SORT posts. In the case of vote disparity, it might be somebody thought the sort order of posts was off and used the full weight of their vote (1 up + 1 down = sort weight of 2) to get the sort in line so the most useful answer would get to the top.
@Caleb I upvote answers that deserve it, but I would never downvote a correct answer, period, as this is a discouragement to providing correct answers. Otherwise I would too much be in the position of downvoting (correct, but less thorough) answers to a question that I have answered, which seems like gaming the system excessively.
I do sometimes feel that I've gotten less votes for a better answer, but again, systems have trade-offs. I do not think that S.E. would be perfect "if only everyone used it properly", etc.
@Caleb Out of curiosity, have you ever down voted a question to, as you say, "correct the sort" and actually left a comment , "Although this is answer is correct, I am downvoting because there is a better answer"?
@goldilocks Maybe you would never do that. but you don't determine what votes mean to other people or control when they use them or don't use them. You need to realize it's' a crowd sourced system and different things trigger vote actions for different people. Some people may use it for the reason I described, and that is not wrong. That is the system working how it was designed to. The aggregate of different people's reasoning for voting is what makes the final result a useful metric.
@goldilocks As a matter of fact I have, but very infrequently (and not in this case!)
And no matter what the reason it is rarely a good idea to comment specifically that you downvoted. That does not lead to productive interactions. Instead downoting with a comment that only says what is wrong or how the post could be improved with no mention of voting at all is almost always more constructive.
@Caleb Sure -- although my opinion of democracy in general is that what it is best at is keeping tyranny in check, and not necessary producing the best result. That's a system and that's the trade-off. Using S.E. as an example, it is better at discouraging idiocy, etc, than encouraging quality (which it does, but to a lesser extent).
@Caleb This (the propensity for grudges and spiraling negativity) is the ONLY reason I think that leaving a comment for a downvote should not be mandatory. If not for that (e.g., if you could leave a comment anonymously), it should be. Punishment is not correction, and correction should be preferred to punishment. Down voting is inherently negative, but it is a necessity.
Really depends on the question. I tend to give a generic example, and then provide more specific instructions depending on how I judge the OP to handle it on their own. For total newbies I usually provide both generic and full.
@Ramesh If you are reasonably clear (which the current version is) then no, that's ridiculous -- this is the first time I've seen anyone complain "you didn't quote the exact same paths" and I pretty much always use /your/whatever/path unless the original is really short. Dumbing things down excessively is not productive.
@goldilocks, yeah. I checked the command before posting my answer. I normally check the commands that I give as an answer. Anyways, after I posted the answer when I realized, the cp won't work, I was trying to fix it. But in the mean time, the OP had accepted which is unbelievable :)
First of all, yes, I have read LinuxAteMyRAM, which doesn't explain my situation.

@Ramesh I think you're reading something into that comment and missing the point it was trying to make. The issues is not that your code does not use the same path examples as the OP (that is never really expected) but that the OP describes a tree scenario where he wants instances of a file from multiple points in the tree to be flattened into a single dir structure. Your code does not handle a tree at all, it only handles the current directory.
Also @Seth re your comment there: your argument about the OP accepting it being evidence that it doesn't need fixing it because the OP for some reason accepted that answer before it was even fixed to do anything at all (the first version was broken in a way that would have totally messed things up and not done anything useful ever if the paths had been adapted).
@goldilocks Turns out I needed to use :%s, not just :s. Root Access chat room got it for me. Vim was complaining it couldn't find any patterns matching a colon.
Did not know about using %s to make things apply to the whole buffer tho! I always use g100000 or something. WRT version, start vim with no doc and it says.
@CanadianLuke Well -- g means global as per regexp generally, but what "global" means to vim is "the current line". So without g, you would replace only the first colon, with g you'd replace every colon in the line; with g10 it would apply to this line + the next 9. Hence, starting at the top and using g10000 generally covers things -- but as I just learned, %s will make it buffer wide :) Vim is an endless learning experience...
If it was, I would agree that the criticism is bogus. But I think the commenter just failed to explain the problem he saw (at least if he and I saw the same thing). Most of the other answers handle the tree scenario, that answer does not.
@derobert Depends. If it's a desktop, I'll have built it myself and thus bought new ram. In that case i usually memtest before installing winders. If it's a laptop that wasn't configurable the first thing i do is get a new SSD (if it needs one) and new ram. Then I memtest.
@DavidFreitag exactly. But sometimes I've just gone ahead and done the Debian install, when I'm fairly confident the RAM is good, and then I do the memtest from the grub menu.
Obviously, bad RAM would mean time to reinstall. But it was a 30-minute install, so no big loss.
@derobert Nope. That's how I discovered my RAM had been miss packaged for the last desktop I put together. I ordered 16 Gigs. Memtest told me I had 32 Gigs when I got the build together.
@FaheemMitha, I know but sometimes it will be encouraging for newer users to answer more questions if they are upvoted. Though I agree it should be for the quality rather than the quantity.
I don't see how I possibly deserve any down votes, but there are some late answers there that definitely deserve up votes. Note that none of them is explicit about how to actually change the value, they just pinpoint its origin further.
I've run it for years on every system I've got my hands on (which is probably only 200 or so)... and I've only ever had bad news from it. You're lucky.
The answer I linked to above is not explicit about how to change the value (which I pointed out) but it did give all the relevant files, so unless the build actually rewrites stuff on the fly it should just be a matter of changing those lines.
@Caleb so you got double the RAM you ordered? Are you required to do anything about it?
I just did a scan with my new Brother multifunction CP-7065DN printer using the SANE frontend gscan2pdf. The paper in question was handwritten, and the scan was too light. When I reprinted the scan, it was significantly lighter than the original; too light.
I'm interested in ways to fix this pro...
@FaheemMitha LOL, sorry my scan filters were a little off. This is why automated spam filtering, reply threading, etc. are hard. Even humans can't always filter messages correctly.
@FaheemMitha I'm a bit OCD, but at the same time it is rarely seen as important to the people already chatting out of place (after all you've already found somebody to chat with so why would you care) but if you are another visitor dropping by now or later looking for what the election buzz has been it's helpful to have it all in one place. A lot of things will get repeated as well and it's easier to search and quote in one room than across several.
@derobert Ha, I didn't realise we were writing for posterity. Dammit, I'm going to have to pick my words more carefully. Four score and seven years ago...
@FaheemMitha BTW, I looked at your scanning question. It's weird that its substantially lighter, the default settings ought to produce more or less the same brightness. If you scan something and pull it into GIMP, check the histogram, is the entire space used?
Colors -> Levels, you should see which values are used... You may need to click the logarithmic scale button above the chart to see colors other than white.
Lost a line? I edited out the first bit, after I realized it didn't need repeating (was going to post as a comment, but decided to put it here, as it's going to lead to more discussion...)
@FaheemMitha the software levels are basically that interface in GIMP... those are the black point, white point, and gamma
So you can find the right values in GIMP very quickly (because as you move them, you instantly see the result) and then put them into the scanning software.
@FaheemMitha Good question. Let see if I can find if it actually deals with white/black point (which is I'm pretty sure the lack of contrast you're seeing)

@FaheemMitha grayscale->B&W was in the docs. Black & white point weren't, and neither did grep'ing the source find anything about them. So I think it doesn't, but can't be entirely sure.
@Gilles, thanks. But I cannot guarantee the above command is faster than the original command. So it would be better if my answer is there in the comment section itself.
