symlink

问题 I need to create symlinks in frameworks inside an app on OSX (vers 10.10.1). I am outside of XCode as the app is developed in Qt. It provides the frameworks, but they need some retouches to work on the new codesigning rules. I call "ln -s path_origin path_target_link" and apparently it works, the links are created and they resolve to the right place. But when I codesign the app, I get an error "unsealed contents present in the root directory of an embedded framework" (In order to verify my

问题 I am running a linux (ubuntu) system within a virtual box container. I used symlinks in the shared directory, which needed some extra work as described here: https://www.virtualbox.org/ticket/10085 This worked very well for my requirements running a Windows 8 host. Now, I switched to Windows 10 and the symlinks do not work any more. I am still able to create symlinks, but the correct path cannot be resolved. Using readlink, I can see that the created symlink is wrong. If I create a symlink

问题 Related: single node_modules folder for multiple projects If npm install -g everything is not recommended, and I do not want to link individual modules, can I possibly symlink <some project>/node_modules to a common directory to be shared by multiple projects? 回答1: Node can handle the symlinks perfectly fine. How to achieve this is going to depend on some of your objectives. The most important being: what experience do you want to have for other developers who download your project(s) from

问题 I'm not exactly sure how to go about doing this, but I need to create symbolic links for certain files in one directory and place the symbolic links in another directory. For instance, I want to link all files with the word "foo" in its name in the current directory bar1 that does not have the extension ".cc" and place the symbolic links in a directory bar2. I was wondering if there was single line command that could accomplish this in LINUX bash. 回答1: Assuming you are in a directory that

问题 I accidentally typed: sudo ln -sf /usr/local/bin/python2.5/ /usr/bin/python instead of: sudo ln -sf /usr/local/bin/python2.5 /usr/bin/python Now bash tells me that /usr/bin/python is not a directory whenever I run python. ls -l /usr/bin/python gives me expectedly /usr/bin/python --> /usr/local/bin/python2.5/ Is there any safe way to remove that symbolic link to a directory (that does not exist) and replace it with a link to the intended file? Arigato in advance if you have any ideas. I am

问题 In Linux, if you have a path to a file which you know is a symlink, how do you programmatically determine (in C or C++) the path to the file that it points to? 回答1: The readlink function. Do a man 2 readlink . This function is part of the Posix API, so it should work on almost any Unix. If the path starts with a '/' , then its an absolute symlink and you have the full absolute path of the file to which it refers (which may be another symbolic link, and you'll have to repeat the process again)

问题 I have a situation where a user is attaching files within an application, these files are then persisted to Azure Blob storage, there is a reasonable likelihood that there are going to be duplicates and I want to put in place a solution where duplicate blobs are avoided. My first thought is to just name the blob as filename_hash but that only captures a subset of duplicates, then filesize_hash was then next thought. In doing this though it seems like I am losing some of the flexibility of the
