man set is not found in bash? I am using bash  I wanted to read the documentation of set  But when i typed man set,it is showing   No manual entry for set    But when i code  set hit="COVID19" echo $1   it prints as   hit=COVID19   How to find and add the man page of set inside the current man pages.
Why don't shell builtins have proper man pages? All shell builtins share the same manual page:  BUILTIN(1)                BSD General Commands Manual               BUILTIN(1)  NAME      builtin, !   etc.   Then there is a little text describing what shell builtins are, and then a list that  looks something like this:    Command       External    csh(1)    sh(1)        !             No          No        Yes        %             No          Yes       No   But if we do man grep we get sections such as   Bugs History See also Standards Description   etc.  Don't shell builtins have their own history, description and arguments like -A or -r? Why isn't that provided in the manual pages and how would I learn to use them correctly and efficiently?
I set up Windows 10 and have been using it for months on a spare laptop.  When installing, I did not use a Microsoft account to enable all of the app connectivity because I don't need that functionality.  I do not want these features active on this device, and I used a simple user name during the install.  Everything was going fine until I read about the Linux/bash features that are available in the anniversary update.  I decided to try them out and entered my Microsoft Insider credentials to enable the features in the developer options of the Control Panel.  I didn't realize the primary account on this device would now become linked to that Microsoft account.  Is there a simple way to disassociate the Microsoft account from the local account, or are they now linked forever in an unholy union?  I can set up a new local account, but I'd rather not lose all the settings and folder preferences prior to my gaffe. solution for apex cpu time limit exceeded exception What is behind the definitions of work and energy? New post formatting Update 3 It took me longer than I wanted, but I’ve got some updates for you on our s-prose component. You can see the  with my thinking over at our design system’s repo. It does the following:  Spreads s-prose headers out from paragraphs for better grouping. Tightens up s-prose paragraphs a bit, and made sure spacing under headings are more consistent. Replaces all s-prose margins internal to the component with a CSS variable var(--s-prose-spacing) so our users can more easily tinker with it in their browsers and user scripts. Kills trailing margins in s-prose  You can see  of content at our Stacks documentation.  Update 2 I’ve split the difference between the original 1.3 line-height and the proposed 1.6 line-height. We’re now at 1.5, with additional refinements to spacing between elements. I’ve also reduced line height within code blocks back to near the original value.  Update 1 This is now live.  We’re doing a bit of refactoring on our post formatting. Currently, we apply a single class with both layout and styling called .post-text. Our first goal is to separate layout from our text styles. Simple enough! However, our current post styling has a few missing spots and areas for improvements. Using our  as a sandbox, we’ve beefed up our styling and created a new component called .s-prose. It’s designed to offer styling for everything the  spec allows. This should allow us to add Stack Overflow-flavored styling anywhere we need to consume Markdown—questions and answers, of course, but also things like user profiles. Our .s-prose component adds:  Proper formatting for   Further header support and better spacing there  Additional blockquote refinements.  Refinements for revealing spoilers. We now reveal this on click / tap for a more consistent experience across devices—fewer accidental reveals as well, since it’s no longer a :hover interaction. Clicking again does not hide the spoiler. We also now add a badge to the top right corner. You can see how these work on our . It looks something like this:   This is a spoiler  It has two lines   General refinements to spacing including nested lists, images within lists  Sizing variations for different contexts. We offer xs, sm, and md variations of the .s-prose component.   As with everything, our prose component is a work in progress. We think we’ve got a heck of a start to a reusable component. We plan on going live with the new component network wide on Thursday, August 27, 2020. We’ll edit this post if that changes. If you see something funky, let us know. Some things are intended but might feel like regressions—images have a slightly different baseline—but others may have slipped through the cracks. The LaTeX Wikibook :     Please understand: you do not have to use floating tables. It only   looks more professional. If you want to place your tables where they   lie in your source code, do not use table at all! This is a very   common misunderstanding among newcomers.   LaTeX works with an intricate , but I often prefer immediate placement with the H placement specifier (enabled by the float package).  My understanding is that captions and table/figure numbering require the table/figure environments. Is this really so, or are there ways around that? What other reasons are there for using table/figure if we know that we don't want a particular object to float? Why is rendered viewport faster than rendering individual frames? When I'm using rendered viewport it initially takes a while before rendering starts, but once it does, I can freely move around and rendering a new view happens almost instantaneously. When on the other hand I'm rendering a movie, for each frame Blender takes a significant amount of time before rendering even starts, usually doing the following:  Synchronizing object, Updating images, Updating meshes, Updating Scene BVH, Packing BVH,  Why does it do this? And is it possible to disable this to increase movie rendering speed? Maximum power of $2$ which divides $3^{1024}-1$ What is the maximum power of $2$ which completely divides $3^{1024}-1$?  I proceeded thus: $\phi(2^n)=2^{n-1}$ for all $n\ge1$ $$3^{1024}=3^{2^{10}}\equiv1\pmod {2^{11}}$$ $$3^{1024}-1\equiv0\pmod {2^{11}}$$ Since $\phi(2^{11})=2^{10}$.  So, maximum power of $2$ must be $11$. But the answer says it is $12$. Where am I wrong and how to solve it correctly? How do I disable negative scaling? By default blender allows you to scale past 0 - how do I prevent this?  i.e. it's common in other 3D modelling software to resize a set of vertices against an axis to align them - however this isn't possible when negative scaling is enabled. Windows 10 sees much more monitors than I have If we have a point charge and outside of it we have a non-conducting Gaussian sphere, then Gauss's law says that the net flux should be zero. I agree that the total field lines coming in are equal to the number of field lines coming out, but isn't it true that the magnitude of the electric field at those segments of the sphere where the field is coming in is greater than those where it is coming out? So when we integrate, wouldn't these areas, having a greater electric field, contribute more to the net flux? I don't see why they would cancel each other out. When given $p = 5, q = 11, N = 55$ and $e = 17$, I'm trying to compute the RSA private key $d$.  I can calculate $\varphi(N) = 40$, but my lecturer then says to use the extended Euclidean algorithm to compute $d$. That's where I get stuck.    Here's my work so far:  First I use the Euclid algorithm to calculate:  40 = 2(17) + 6  17 = 2(6) + 5 6 = 1(5) + 1 = gcd   So I know the GCD is 1. Applying the 'extended' section of the algorithm:  6 = 40-2(17) 5 = 17-2(6) 1 = 6-1(5) 1 = 6-1(17-2(6)) 3(6) = 1 (17) 3(40 - 2(17)) - 1(17) 3(40) - 3(17)   I know the answer is $33$, but I have no idea how to get there using the extended Euclidean algorithm. I can't figure out why I'm getting $3(40) - 3(17)$ when I know the answer should contain $33$. I am using an USB port as a power supply. Is there a way I can take the weak 5V of a regular laptop USB and transform if to 100V+ while begin in the smallest package possible. I've heard of boost converters but they are usualy too big. I want something that has the size of like a normal USB key.   What I want to do is to charge up around 5 capacitors at 100+V and then discharge them later. Power efficiency not a concern for me.  It would be helpful to include a schematic of the circuit. hyperlink name with biblatex authoryear (biblatex 1.4b) I'm new here so I'm not sure if this is the right way to express my question:  I'm using the excellent biblatex package with the author-year style and want the links in my citations to include the name of the author as well as the parentheses. The answer presented at  did exactly what I wanted but it seems the solution is broken with the newest biblatex version 1.4b. Can anyone help me by adapting the code to the newest biblatex version? What's the simplest way to call Http GET url using Delphi? There's a web services I want to call in my application, I can use it with importing the WSDL or by just use "HTTP GET" with the URL and parameters, so I prefer the later because it's simple thing.  I know I can use indy idhttp.get, to do the job, but this is very simple thing and I don't want to add complex indy code to my application.  UPDATE: sorry if I was not clear, I meant by "not to add complex indy code", that I don't want add indy components for just this simple task, and prefer more lighter way for that. How to make the numbering of subsections independent from the numbering of sections? I am writing a constitution for a society.  I would like to have the subsections numbered independently of the way that the sections are numbered, i.e:  Section 1     Subsection 1     Subsection 2 Section 2     Subsection 3   How can this be done? in the street or on the street How can we prove that a binomial coefficient $n\choose m$is divisible by the ratio of $n$ and $\gcd(n,m)$? Prove that for every $n\geq m \geq1$ natural numbers, the following number is an integer:  $${\gcd(n,m)\over n}\cdot{n\choose m}$$  Where $\gcd$ is the greatest common divisor.  I tried to make it simpler by cancelling the $n$ from the left side, and making it $(n-1)!$ on the right: $\gcd(n, m) \cdot \frac{(n-1)!}{m!(n-m)!}$, but can't really go further.   This was problem B-2 on the . I'm trying to find out why my application is very slow on a certain machine (runs fine everywhere else). I think i have traced the performance-problems to hard-disk reads and writes and i think it's simply the very slow disk.  What tool could i use to measure hd read and write performance under Windows 2003 in a non-destructive way (the partitions on the drives have to remain intact)? Why have header files and .cpp files? Why does C++ have header files and .cpp files? sObject ' ' type is not supported Hey everyone I've been seeing this a lot lately and am trying to figure out why this error is thrown when querying the SOAP API directly. I've tried several very basic SOQL queries such as  SELECT Body FROM AssetFeed   Only to be met with the sObject type 'AssetFeed' is not supported. error.  The account that I'm currently querying is just a standard user who accepted permission from an app that was created by a Developer Account, so I'm wondering if it might be permissions from the user or permission from the app itself? Possibly because Developer accounts cannot use 95% of whats offered?  The WSDL used is a v27.0 generated Partner WSDL if that helps narrow it down.  I've noticed this in multiple standard objects, so I'm wondering what the trend really is? Seems like a good informational question for future googling of others?
