Why does “local” sweep the return code of a command?

问题 This Bash snippet works as I would\'ve expected: $ fun1() { x=$(false); echo \"exit code: $?\"; } $ fun1 exit code: 1 But this one, using local , does not: $ fun2() { local x=$(false); echo \"exit code: $?\"; } $ fun2 exit code: 0 Can anyone explain why does local sweep the return code of the command? 回答1: The reason the code with local returns 0 is because $? "Expands to the exit status of the most recently executed foreground pipeline." Thus $? is returning the success of local You can fix

问题 I have been developing an AJAX application using jQuery and Microsoft Seadragon technology. I need to have access to the html5 canvas function toDataURL. With Google Chrome, the same origin rule applies to this function which means that a page run locally (with the file:/// in the URL) failed to satisfy the same origin rule and an exception is thrown. With Chrome 7, starting the application with --allow-file-access-from-files option, allows to call canvas.toDataURL() from local files. However

问题 I was looking into xslt and started testing with the examples on w3schools. However, when I save the xml and xsl in files and try opening them locally, chrome won\'t perform the xsl transform. It just shows a blank page. I have added the <?xml-stylesheet type=\"text/xsl\" href=\"style.xsl\"> tag to the xml document, and firefox renders it as it is supposed to look. Also, if I look at the files through a web server, chrome displays the file as it is supposed to look. Is it that chrome has a

Returning local data from functions in C and C++ via pointer

I have argument with my friend. He says that I can return a pointer to local data from a function. This is not what I have learned but I can't find a counterargument for him to prove my knowledge. Here is illustrated case: char *name() { char n[10] = "bodacydo!"; return n; } And it's used as: int main() { char *n = name(); printf("%s\n", n); } He says this is perfectly OK because after a program calls name, it returns a pointer to n, and right after that it just prints it. Nothing else happens in the program meanwhile, because it's single threaded and execution is serial. I can't find a

问题 There appear to be many solutions that are very close to addressing my problem but of the dozens and dozens of questions I\'ve poured through not one seems to exactly address what I\'m trying to do. Although I have seen nearly the same question asked without an answer. I have tried so many combinations of options and functions to no avail. I want to use the modal form to add a new row with the inputted values to the jqGrid but I do not want it to post to the server upon Submit. I do want to

问题 I am actually new to programming in Java but I have been following several solutions to my problem here but didn\'t find one that suits my case and I can\'t seem to get the code down correctly. I would like to have a WebView that opens an online page (for example Google) when the phone is online and open a local HTML page when the phone is offline. At the same time though I want the phone to overwrite the local page when it is online so that the offline local page is always updated to the
