symlink

问题 I have a zipfile which is stored in memory as io.BytesIO buffer. Within, the zipfile, I need to create a symlink to one of the directories. Below is what I have tried so far (from this similar question on SO) but it is not creating the link as I want at top level. Link to be created to : root/scale/lib/hypervisor/kvm/pika_3_5 Link name : 'pika' Link location : at top level Existing Zipfile : data['egg_buffer'] with zipfile.ZipFile(data['egg_buffer'], 'a') as zip_buffer: dest = 'root/scale/lib

问题 In my project I use a JSON file as a database (which is currently stored in local on my computer). It is modified by Node.js and some pieces of information are rendered with React in an import : import Data from 'myPath/appData.json'; I cannot have my database in the src folder because the build is static, and my databse must be dynamic. I get this error : Failed to compile. ./src/components/Ligne1.jsx Module not found: You attempted to import myPath/appData.json which falls outside of the

问题 I'd like to be able to layer other branches on top of an existing branch, and have those branches be revisioned independently. This would be useful, for example, to allow the binaries for various subprojects to be unified into the same bin directory. In general a given file would only be present in one layer. Ideally I guess I would use a unionfs to accomplish this, but it would have to somehow provide a way to access the various .git directories, which are to appearances all subdirectories

问题 How can one recursively find all the symbolic links in a directory in Unix? Something like this find . -name *.o but for symbolic links along the lines of find . -type symlink ??? 回答1: find . -type l Should work. http://linuxmanpages.com/man1/find.1.php 来源： https://stackoverflow.com/questions/4611595/find-symbolic-links-in-a-directory

问题 I'm working on some linux kernel stuff and I have a fake path called /dev/blah/whatever that points to /dev/block/real_device The issue is that lookup_bdev will fail to follow the symlink so I'd like to massage the path upfront by getting the real path (/dev/block/real_device) so I can hand that off to lookup_bdev so it returns successfully instead of an error. Or any other kernel call that would correctly retrieve the block_device information given the initial path. Thanks 回答1: Use VFS layer

问题 I write ant build script. I need to create a symlink and I found symlink task. According to manual, it works only on Unix. What happens if someone run my build script on windows platform? Will build fail? Or this task will be ignored on windows platform? Or in case of NTFS drive, it will even work? 回答1: I'm running Win7 and I tried it. Since I have Mingw installed it used ln. Ln seemed just to copy everything. Since a normal Windows installation does not have ln, it would fail there. Here's

问题 I'm working in a UNIX environment where /bin has been set up like this: -rwxr-xr-x 1 root root 617144 Nov 19 2009 bash lrwxrwxrwx 1 root root 4 Nov 23 2010 sh -> bash In my environment I have set $BASH_ENV to point to my local .bashrc: env | grep BASH BASH_ENV=/home/users/atomicpirate/.bashrc In addition, .bashrc has as its first line echo BASHRC READ . I would expect /bin/sh and /bin/bash to behave exactly the same with this setup...but they don't: /bin/bash -c 'echo $BASH_ENV' BASHRC READ

问题 I am setting up a project that will be shared among several programmers at my organization. We are using git--to which I am a newcomer. The project directory includes symbolic links to documentation directories that should not be under version control. I want to maintain the symlinks under version control as symlinks, rather than having them dereferenced and all of the content of the symlinked directory placed under version control. I find that the git command line tool behave the way I want:

问题 Windows native alternative for ln -s is mklink . Is there any native alternative for readlink ? Or how to natively identify if the file is symlink? 回答1: I don't believe there's any tool directly equivalent to readlink . But you can see in the output of dir whether an item is a symlink or not, so you can still determine this from the command line or in a script. Test whether it's a symlink or not You can pretty easily test whether a given file is a symlink using syntax like: dir mysymlink |

问题 I wrote a simple script to automate creating a symbolic link. #!/pseudo today = "/tmp/" + date("Y-m-d") exec("ln -sf " + today + " /tmp/today") Simple enough; get today's date and make a symlink. Ideally run after midnight with -f so it just updates it in-place. This works just fine! ...for my user. xkeeper /tmp$ ls -ltr drwxrwxrwx xkeeper xkeeper 2014-10-21 lrwxrwxrwx xkeeper xkeeper today -> /tmp/2014-10-21/ xkeeper /tmp$ cd today xkeeper /tmp/today$ cd .. Notice that it works fine, all the
