symlink

问题 I'm trying to create a script that searches through a directory to find symlinks that point to non-existing objects. I have a file in a directory with a deleted symlink, but for some reason when i run the below script It says file exists. #!/bin/bash ls -l $1 | if [ -d $1 ] then while read file do if test -e $1 then echo "file exists" else echo "file does not exist" fi done else echo "No directory given" fi Thanks 回答1: Check this page. It has a test for broken links. It uses the -h operator

问题 I need to move multiple symlinks within a VOB in a dynamic view. As described in my previous question, this is not as trivial as it sounds (to me), as the target path is saved relative to the link itself and not to the VOB root or anything like that. This wouldn't be a big issue, if ClearCase would adjust the path information in those links, but appearantly, it does not. Details: Let's assume following folder structure: /myVOB /Originals /LinksA /SubDir /LinksB Then moving a link to the file

问题 Is there a way in Python to check whether or not a file is a symlink to another specific file? For example, if /home/user/x symlinks to /home/user/z , but /home/user/y links somewhere else: >>>print(isLink("/home/user/x", "/home/user/z")) True >>>print(isLink("/home/user/y", "/home/user/z")) False >>>print(isLink("/home/user/z", "/home/user/z")) False (/home/user/z is the original file, not a symlink) 回答1: import os def isLink(a, b): return os.path.islink(a) and os.path.realpath(a) == os.path

问题 Here I received a solution to my problem that every time when I deploy my Spree Commerce app with Capistrano my images are removed (they are still there, but the folder names are wrong) and I have to add them again via admin. Both on this Google group and in the answer to the question it is said that symlinking is solution. You need to make sure that your RAILS_ROOT/public/spree directory is being symlinked in from the Capistrano shared directory and not recreated every time you deploy. If

问题 When a file is loaded/required via a symbolic link, all the methods, keywords, etc. that refer to a file name seem to refer to the link name, and not the real file name. For example, suppose I have a file foo.rb with its contents something like: puts __FILE__, __dir__, caller and a symbolic link bar.rb pointing to foo.rb . If I load/require foo.rb via the symbolic link bar.rb , then all of the file names given by the commands above describe the symbolic link name bar.rb , and not the real

问题 I am trying to install opencv on Mac OSX Lion. brew install opencv I get the following error (and a few other similar ones) Error: The linking step did not complete successfully The formula built, but is not symlinked into /usr/local You can try again using `brew link jpeg' When I do brew link jpeg Linking /usr/local/Cellar/jpeg/8d... ln: wrjpgcom: File exists I do not understand what this means? What should I be doing? Thanks 回答1: Check for the following files in the /usr/local folder: bin

问题 I need a couple of symlinks in my project. From src/openlayers , folders img and theme have to be symlinked in contrib/openlayers . The contrib/openlayers folder should also be created automatically. .PHONY: run run: contrib/openlayers/theme contrib/openlayers/img ../bin/pserve development.ini --reload contrib/openlayers/theme: ln -s src/openlayers/theme $@ contrib/openlayers/img: ln -s src/openlayers/img $@ But this rule tries to create symlinks every time. (I put -f flag to ln , so it re

问题 I have a script that is symlinked from one folder to another /var/www/default/index.php which is symlinked to /var/www/mysite/index.php However when i call DIR from mysite the path resolves to the origial path under default. How do i make it return the mysite path (the symlinked folder, not the actual folder) 回答1: For Web Server requests dirname($_SERVER['SCRIPT_FILENAME']) will give you what you need. Failing that $_SERVER['PHP_SELF'] or even REQUEST_URI may have what you need, depending on

问题 I try to create symbolic link on Windows (as 1st answer to Is there any way to integrate Eclipse with Gradle in Android project?) On linux it is ln -s src/main/res res ln -s src/main/AndroidManifest.xml AndroidManifest.xml Windows 7 has mklink util, but it just did not work on my PC. I found a great Junction util and could do junction res src/main/res , but for link to file is created .lnk file (aka Windows shortcut). I discovered that Git Bash can execute ln -s src/main/AndroidManifest.xml

问题 I'd like to change the structure of our source code inside ClearCase before using a custom script to export that to another SCM system. As the original code may still change slightly, I did this by symlinking the contents of the existing folders into the new structure. Now the desired folder structure has changed and I need to move those symlinks (or start the whole process over, which is my fall-back strategy if no one can help me here). But after moving any symlinks (inside the same VOB in
