symlink

问题 My searches have only shown me how to create symbolic links using mklink in cmd. I have seen some things saying to use readlink , but PowerShell and cmd don't know what readlink is, and cd obviously doesn't work. So how do I follow one? 回答1: For your question i made this batch file: mkdir truedir dir > truedir\fileone.txt mklink /d symdir truedir cd symdir dir And i have found no problem to get the content of the symblic link to a directory from command prompt. No problem also with powershell

问题 I'm trying to crawl the entire file system of an android device, both directories and files, without the benefit of NIO, to build a tree of it. If I had NIO then I could use WalkTree or similar, but I don't. The problem I am having (on the Nexus 5 API 23 x86 emulator) is in /sys/bus/pci/devices and possibly other directories (eg /proc/self ) - it doesn't complete before the app times out/quits/crashes (unknown which), possibly getting into some kind of loop or something (the path may change

问题 I want to read a symlink, and get the details of the link itself, not the contents of the linked file. How do I do that in Node, in a cross-platform way? I can detect symlinks easily using lstat , no problem. Once I know the path of the file, and that it is a symlink though, how can I read it? fs.readFile always reads the target file, or throws an error for reading a directory for links to directories. There is a fs.constants.O_SYMLINK constant, which in theory solves this on OSX, but it

问题 Currently in my Mac I have these JAVA versions: MyMac$ cd /Library/Java/JavaVirtualMachines $ ls -la total 0 drwxr-xr-x 4 root wheel 136 17 Oct 11:21 . drwxrwxr-x 5 root wheel 170 17 Oct 11:21 .. drwxr-xr-x 3 root wheel 102 14 Jul 22:52 1.6.0.jdk drwxr-xr-x 3 root wheel 102 17 Oct 11:16 jdk1.7.0_79.jdk What I am trying to do is change the symbolic link to point to JDK 7 instead of JDK 6: $cd /System/Library/Frameworks/JavaVM.framework/Versions $ls -la drwxr-xr-x 11 root wheel 374 17 Oct 11:21

问题 Is it possible in Android to have a SymLink (Symbolic Link) that leads to a point higher in the directory tree than the initial directory, so leading to a loop? For example: / Parent Child SymLink to directory '/Parent' This would loop if you try to crawl it with File.listFiles() . If so, how can one avoid it, other than not following SymLinks? Sure, we could check if a link points to a parent directory, but more complicated structures would break that: / Parent1 SymLink to /Parent2 Parent2

问题 I'm battling with cygwin for quite a while now. I searched far and wide on how to make cygwin create Windows-style symbolic links. I tried the following: export CYGWIN="winsymlinks:native" export CYGWIN="winsymlinks:nativestrict" export CYGWIN="winsymlinks:lnk" I also tried exporting w/o the quotes. I also tried from both cygwin/x86 and cygwin/x64 For the life of me - I can't get the Windows native symlinks to work. I'm working on Windows7/64bit; cygwin version 1.7.25. I'd love to get a

问题 I would like to safely be able to simulate open with O_CREAT | O_WRONLY | O_TRUNC | O_NOFOLLOW and O_CREAT | O_WRONLY | O_APPEND | O_NOFOLLOW on systems that do not support O_NOFOLLOW . I can somewhat achieve what I am asking for with: struct stat lst; if (lstat(filename, &lst) != -1 && S_ISLNK(lst.st_mode)) { errno = ELOOP; return -1; } mode_t mode = S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH; int fd = open(filename, O_CREAT | O_WRONLY | O_TRUNC | O_NOFOLLOW, mode); but then I

问题 Whenever I attempt to import cv2, I always get this error import cv2 Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /usr/lib/libgdal.so.1: undefined symbol: sqlite3_column_table_name I've already created a symbolic link and I have also already installed the libgdal-dev module from the Ubuntu Software Center. Any ideas? Thanks! EDIT : I did as pbu suggested, and the link was created without fail for the most part. But now, this error comes up: import cv2
