I am trying to do some tests to see if I can execute a shell script in a variables contents, similar to the Invoke-Expression function in powershell. I am getting the contents of the variable from curl: a=$(curl https://some.site/test.sh) however, whenever I print out the variable, it only gives the last line of the shell script. Is there something I'm missing here? I'm using echo $a to print the variable.
Or, an introductory guide to robust filename handling and other string passing in shell scripts.  I wrote a shell script which works well most of the time. But it chokes on some inputs (e.g. on some file names).  I encountered a problem such as the following:   I have a file name containing a space hello world, and it was treated as two separate files hello and world. I have an input line with two consecutive spaces and they shrank to one in the input. Leading and trailing whitespace disappears from input lines. Sometimes, when the input contains one of the characters \[*?, they are replaced by some text which is is actually the name of files. There is an apostrophe ' (or a double quote ") in the input and things got weird after that point. There is a backslash in the input (or: I am using Cygwin and some of my file names have Windows-style \ separators).   What is going on and how do I fix it?
Unable to load styles and script from static resource in LWC after summer'19 release Deriving Chinese Remainder Theorem from gcd Bezout identity I'm looking for a high current DC switch (able to switch something like 5V@30A) and I've encountered several DPDT that might do what I need, however they are only rated for AC applications (3A@250VAC or 6A@125VAC). Are these rating convertible to DC? or is that something that only the facturarer would know? How to apply CSS to iframe? I have a simple page that has some iframe sections (to display RSS links). How can I apply the same CSS format from the main page to the page displayed in the iframe? How do I create a file of size 10M, format it with ext3 filesystem and then mount it in /media/fuse?  I tried with  mkfs -t ext3 file   then to mount it  mount -t ext3 file /media/fuse   It didn't work because it said that file wasn't a block device. Can anybody help me? I wanted to apply texture on some house following an tutorial, I'm sure I did all what was needed but still don't see the texture.  Here's a screenshot: Finding the conjugate hyperbola Assume we are given a general proper hyperbola $  a_{11}x^2 + 2 a_{12} x y + a_{22} y^2 + 2 a_{13}x +2 a_{23}y + a_{33} = 0$ with  $D =\det \begin{pmatrix}   a_{11} &amp; a_{12} \\   a_{12} &amp; a_{22} \end{pmatrix} &lt; 0$ and $ A = \det \begin{pmatrix}   a_{11} &amp; a_{12} &amp; a_{13} \\   a_{12} &amp; a_{22} &amp; a_{23} \\   a_{13} &amp; a_{23} &amp; a_{33} \end{pmatrix} \neq 0$.  Is there an easy way to find the implicit description of the conjugate hyperbola?  I could translate and rotate the hyperbola and obtain a canonical representation of the form $\frac{x^2}{a^2} - \frac{y^2}{b^2} = \pm 1$, find the conjugate of the canonical one and the transform back. However, I'm looking for a more straightforward way to achieve this. invalid EFI file path on windows 8 How to deploy EJB based application on Tomcat If you are not satisfied with answers on someone else's question, should you ask your own? Suppose you had a question, and you really want a good answer that would solve your problem, but noticed it was already asked by someone else. Now, a lot of answers had been posted and upvoted, and maybe one was accepted. However, none of the answers solved your problem. The system does not promote the question very much because it is not considered "unanswered", and a lot of users who would otherwise bother to give a correct answer will probably skip the question completely as there are already many highly-voted answers.  Now, what should you do in this case?  One idea is to ask a new, completely identical question, but now you're in control to decide when it is answered. But would that go against SE policy? How do I avoid conversation with strangers while traveling? In iOS, I only need to be asked once whether I want to allow a website to share my location data. Is it possible to permanently do this in OS X version of Safari as well? As I have heard people did not trust Euler when he first discovered the formula (solution of the ) $$\zeta(2)=\sum_{k=1}^\infty \frac{1}{k^2}=\frac{\pi^2}{6}.$$ However, Euler was Euler and he gave other proofs.   I believe many of you know some nice proofs of this, can you please share it with us? If $ a$, $ b$, $ x$, $ y$ are integers greater than $1$ such that $ a$ and $ b$ have no common factor except $1$ and $ x^a = y^b$ show that $ x = n^b$, $ y = n^a$ for some integer $ n$ greater than $1$.  I started this way: $x^a=y^b$ $=&gt;$ $x=y^{b/a}=(y^{1/a})^b$. Thus $x$ is an integer, and so is $y^{1/a}$, so $y=n^a$ for some integer $n$ greater than $1$. Then from the given relation, we get $x=n^b$.   I am not very convinced with my solution, as I feel I did some mistake. Can anyone point out where the mistake is? Any other solution is also welcome :) "Duplicate of...[deleted post]" Comma after introductory words, phrases, clauses: unacceptable, obligatory or optional? Disabling module with config sync and removing with composer I have an issue disabling modules, I've searched but cannot find something useful:  - Developer A disable module and via composer remove it  - I pull his changes so i run composer install that remove the code, then drush cim to update configuration, but it complains that the module is missing while it's trying to delete its configurations.  What's the right way to do this? I can't import config before running composer install because along the uninstalled module there could be also new modules needed for the configuration import. Run Trigger As A Specific User (or Profile)? Is this possible?  I'm not finding help, Google or otherwise, for this.  Situation:  A trigger runs and cycles through groups of Opportunities.  Some of these Opportunities are Closed Won, and most users of the system are not allowed to Edit Closed Wons (especially the Sales team).  But I need this trigger to be able to touch the Opps (it's fired when the User touches the Account and subsequently a group of Opps under that account gets touched).  It is a VALIDATION RULE blocking them.  Ultimately, I may investigate, if no other option, setting a HIDDEN FIELD on the Opp before updating, then clearing if after, and putting bypass code in the Validation rule.  This is a backup plan.  I'd like to know how to "Run As" a specific profile though.  Anyone have an example of this?  I have three profiles out of twelve that can touch Closed Wons...
