@terdon (need your advise) (if matters) For this question, I've currently posted two edits with two command-line example in each edit. also see revision. Now I want to make sure if question became boring. Should I delete "for" command example or any other suggestion that should I do for making it sample. (if matter for visitors to be boring, simple or not-well-explained)
@Pandya - maybe dont change questions substantially from their original (or at least their answered) forms. different questions are just different - not better.
altering the source of a problem alters the meaning of the question - you can only make a question better by better describing the problem asked about - not changing it.
@Pandya 1) Never add "Edit" to your posts. The idea is that SE is like a wiki. You don't write the question/answer only for the 1st person to read it, you must write it in such a way that if I see it for the 1st time in 5 years, it will still make sense. So "edit" is noise. Just make the edits and don't point them out. 2) Since others have pointed out ways of improving the question, just keep the improved version and remove everything else.
There's no point in showing your first (not as good) attempts, just show the best one.
And no, a question should be able to stand on its own, it shouldn't have "EDIT1" and "EDIT2" and "EDITN". That's just noise. If the previous attempts are important, they should be included in such a way as to not break the flow of the question.
@terdon - but i have a point. i completely agree about the edit stuff, though. that is neither here nor there. but there ought to be some reasonably obvious connection to the problem asked about in the first place. wouldnt you say?
it does make sense to simplify some code snippet or whatever - to distill it to the core of the issue.
Well, yes. The problem asked about is "Why is yes so much faster than shell loops". Anyway you look at it, it boils down to the same basic point. To make the question as good as it can be, the shell loop in question should be as good as it can be.
@mikeserv if its that thing about the write buffer, I think he just doesn't know you can drag the bottom of the answer box to make the textarea as big as needed
otherwise I have no idea what our "community write buffer" refers to
Let me give an example:
$ timeout 1 yes "GNU" > file1
$ wc -l file1
11504640 file1
$ for ((sec0=`date +%S`;sec<=$(($sec0+5));sec=`date +%S`)); do echo "GNU" >> file2; done
$ wc -l file2
1953 file2
Here you can see that the command yes writes 11504640 lines in a second while I can write o...
@Pandya the objective is to make the question easily understandable for someone who reads it for the first time after the edits. There's no need to highlight the history of the question's evolution. Just integrate the changes into a coherent whole that can stand alone. As I tried to do to yours.
@terdon but i also there was a chance you understood something differently about it than i did - which is why i tried talking to you about it. twice now.
@Pandya No problem. By the way, here's an even more impressive one:
$ time perl -e 'print "GNU\n" x 30000000 ' > file
real 0m0.790s
user 0m0.067s
sys 0m0.197s
That's 30,000,000 lines in under a second.
@mikeserv I consider it a dupe and did what I was elected to do: I closed it as a dupe. If you disagree, vote to reopen or post on meta. I answered your comment, wasn't convinced by your arguments and have absolutely no desire to get into another long discussion with you. There are mechanisms to deal with this sort of thing, use them.
@mikeserv Perhaps. But one of the side effects to being a self-described jerk is that after the 200th time, people no longer have the patience to deal with you. Not even in the cases where your arguments are valid. It's a shame but there you go.
@terdon - so thats a mere formality then? and moderators should close every question immediately if, in their opinion, a question might be related to some other?
How can I remove all script blocks (including multi-line ones) from html files such as:
<script type="text/javascript">
var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
(function() {
var gads = document.createElement('script');
gads.async = true;
gads.type = 'text/javascript...
I do the same thing where I have a diamond -- I one-vote hammer obvious dupes and egregiously off-topic and I abstain from most others unless its sitting at 4 votes
@mikeserv Yes. When I find things that I consider to be clear duplicates, I will close them as such on my own initiative. If you disagree, you can take it to meta and/or vote to reopen.
@mikeserv I refuse to deal with you when you're in this mood. It is not the first time. Hell, it isn't even the 10th time. You always do this instead of using the tools available and I;ve had enough of it.
@mikeserv the answer on the dupe works perfectly for the OP's example here. I have no idea what ..."...span>"... is supposed to be. In any case, this question has already been answered to the OP's satisfaction so, again, there's no point in having them both open. However, there are mechanisms in place for cases where you feel a question has been wrongly closed: i) vote to reopen and ii) bring it up on Unix & Linux Meta. — terdon ♦18 hours ago
@mikeserv write a level-headed meta post if you want a properly addressed answer. that way it also stays around so future equivalent meta complaints can be dupe-closed to it
@mikeserv simply put, the answer on the dupe answers the question as far as I can see it. The other difference is <span> vs <script> tags, but the result is the same
I am running a Fedora Workstation virtual machine on an Ubuntu host.
I created a folder /home/cl/share in the guest and mounted the shared folder /media/cl/system/virtual/share as root following the instructions from linux-kvm :

@mikeserv that would a malformed page if it did. The contents of the tag are almost always going to be javascript and there is no reason it would emit an html script tag that I can think of.
@terdon The first event of our new kind of Linux information event was in May 2015 at 8 locations in Berlin. The second was in November in 79 locations in 72 cities in three countries (de/at/ch). The next event will be on April, 30th in at least 7 European countries.
@HaukeLaging Sounds interesting. I'd be willing to help but not to tale a very active role. I just started a new job a couple of months ago and don't have much free time. I'd be happy to give a hand though.
@terdon The main problem is to find the right people (in time). Bringing this information to the right people (whoever that may be) or pointing me at them may be much more worth than doing an event yourself.
@mikeserv javascript is Turing complete. You can do whatever you want with it, but yes you can dymaically alter the DOM (add/remove elements, hide/show them, populate them, etc).
@HaukeLaging I don't really have any contacts in the Greek Linux world, I'm afraid. I know it exists but that's about it. I've only been back in Greece for a year now and I'd left in 1998.
@terdon I have one contact in Greece (Pireus?) who wants to help and has told me that there were just very few Linux user groups in Greece. I have written to 12 organizations / mailing lists and he was the only one to reply (not a Greek problem, though).
@FaheemMitha Linux has an estimated desktop "market" share of 1.5%. That is not mainstream. Not nearly. Installing Linux has become much easier over the years but that does not get people interested it can just scare them off.
@FaheemMitha With the LPD 2015.2 we have founded two new LUGs in Germany.
@FaheemMitha You have misunderstood me. A complicated install can scare people off but even a perfectly simple install does not generate interest in the system.
@FaheemMitha If we have a Linux event for non-Linux users twice per year in several hundred European cities (the Italians and French had already 135 each with a similar event) then it should be possible to get media coverage in the nationwide non-IT media. Thus a< lot more people would HEAR about Linux at all.
@FaheemMitha I have thought about that but I thing the event has to becomne a bit more mature for that. Currently we try to get contact persons in as many countries as possible.
@FaheemMitha We were quite surprised by what we have learnt from the first event. Our local press failed completely thus nobody from the target group attended because they didn't know about the event. It turned out that many people who even tried to use Linux before had not even heard of Linux user groups. If they had then they had come to us years ago...
@HaukeLaging Hmm, that's weird. I got the strong impression that everyone who wanted to use free Unix-like systems was already using them, whether it was Linux-based or a BSD, or something else. And that the user groups were passe.
Plus Germany is ground zero for this kind of thing, surely?
I mean, it's probably got among the highest density of tech people on the planet.
@FaheemMitha And, of course, it's not enough to have heard about Linux. 99% of the users have to have seen and used it in order to decide to install it. Those who hate Windows so much that they are willing to switch unseen are too few... And hardly any non-nerd would consider using an OS if he doesn't know anyone who uses it, too.
Though in my case, I got myself a PC in 1998. It has Windows 95 on it. I installed Red Hat 5.2 on it (or whatever it was). I was expecting to use both of them to some extent, because I didn't really know anything about Unix at the time. As it turned out, I basically never used the Windows at all.
In fact at some point it just stopped working for no reason, and I totally failed to notice.
Maybe I should put this in my "getting to know you" answer.
@HaukeLaging Hey, answer my "getting to know you" question!!!! Pretty please.
@HaukeLaging Well, Germans more than everyone else, in my experience.
I thought it would be a nice idea if we could have a question thread where everyone posts an answer where they introduce themselves, talk about themselves a little bit, and tell the community their motivation for participating on this site (unix.stackexchange.com).
Some SE sites don't have much ...
@FaheemMitha OK, that's too far away to care about spreading there soon. But I assume that the LPD will be a worldwide event within a few years. Too easy to organize, too attractive for different types of organizations, too successfull not to spread "everywhere".
Let's say I have a video file that is splitted in multiple parts. Each piece is long 2 Megabyte. Imagine also that i have a list of the Sha256 of each piece and the Sha256 of the full file.

@FaheemMitha the funniest part of that for me isn't that he's asking an impossible question, its that in this day and age he's still downloading pirated video in 2mb chunks, I figured the days of .rar, .r01... .r99 were long behind us.
@HaukeLaging I just got a reply from the Greek Linux group I found (which is a good sign, they actually exist) and they're interested but understaffed. He said he can put up an announcement on their page and will discuss it with the group's board. I gave him your email from the linux-presentation-day page and asked if it would be OK to give you his. I'll let you know if there's anything new.
Let me give an example:
