落花浮王杯 提交于 2019-12-06 19:39:23
问题 What is the difference between test -L filename and test -h filename in ksh shell. From the man page, both were used to identify a symbolic link, but I want to know the exact difference. Here is the description from the man page. -h file True if file exists and is a sym- bolic link. -L file True if file exists and is a sym- bolic link. 回答1: The source code for ksh93 , in file bltins/test.c , shows that these two options are treated exactly the same, except for the author's hopes for the

Modifying a symlink in python

问题 How do I change a symlink to point from one file to another in Python? The os.symlink function only seems to work to create new symlinks. 回答1: If you need an atomic modification, unlinking won't work. A better solution would be to create a new temporary symlink, and then rename it over the existing one: os.symlink(target, tmpLink) os.rename(tmpLink, linkName) You can check to make sure it was updated correctly too: if os.path.realpath(linkName) == target: # Symlink was updated According to

Having project_name/node_modules as a symlink?

十年热恋 提交于 2019-12-06 16:08:38
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? 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 version control? When designing this experience, it is super helpful to read about the Node module loading

Tomcat 7 symbolic link to war file

别来无恙 提交于 2019-12-06 13:51:36
问题 I would like to have a symbolic link in tomcat's webapps directory that points to a war file at another place in my file system, and I would like that war file to be served as the default webapp. I have pieced together the following solution, but the app is not accessible from the browser. I have a folder in my home directory ~/tomcat/webapps. The owner is tomcat7. In this folder, I have my war file, myapp-1.0.war. In my /var/lib/tomcat7/webapps directory, I have a symbolic link: myapp ->

Deleting a symbolic link in java

二次信任 提交于 2019-12-06 13:41:35
Is there any api available to delete a symbolic link using java. Files.delete(Path) didn't work out.Please post your suggestions. Files.delete(Path) is working perfectly on symbolic links. You should have a other issue in your code. This code sample works (JAVA 8): import java.io.IOException; import java.nio.file.Files; import java.nio.file.Paths; ... String symLinkName = "/some/path/to/symlink"; try { if(Files.exists(Paths.get(symLinkName))) { Files.delete(Paths.get(symLinkName)); } } catch (IOException e) { log.info("Cannot delete symbolic link " + symLinkName); e.printStackTrace(); }

If circular symlinks are useless, then why are they allowed?

风流意气都作罢 提交于 2019-12-06 13:17:13
问题 I was just reading this post here: What are circular symlinks in Unix-like systems used for? And the answers were quite interesting. They seem to say conclusively that there is no reason one would ever create such a circular symlink, and therefore it must have been created in error. If this is true, then why on earth are they allowed? Is it because the mechanics of disallowing them are prohibitively complicated or computationally intensive? I don't see why this would be the case: can't we

laravel symlink is changed when code is pushed to live site

大兔子大兔子 提交于 2019-12-06 12:46:52
I am using laravel 5.5's storage symlink to store images. When I push code to the git and pull from live site then symlink path on live site becomes same as is on my local code . My local has this symlink storage -> /home/path/to/project/app/public/ But live site expects this symlink path storage -> /var/www/html/website.com/public_html/project_code/storage/app/public/ Every time I have to delete symlink and create it again on live site. I have do these steps on live site cd public rm storage cd .. php artisan storage:link after doing these steps my symlink becomes according to live site and

How do I selectively create symbolic links to specific files in another directory in LINUX?

守給你的承諾、 提交于 2019-12-06 09:35:41
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. Assuming you are in a directory that contains directories bar1 and bar2 : find bar1 -name '*foo*' -not -type d -not -name '*.cc' -exec ln -s $PWD/'{

PHP realpath on Windows Case Issue

故事扮演 提交于 2019-12-06 09:09:11
I have a symlink on my Windows server which was made like this: F:\>mkdir link-target F:\>mklink /D link f:\link-target (Note the lower case f: in the symlink target) In PHP I run this: $dir = realpath('f:\link'); var_dump($dir); $dir = realpath($dir); var_dump($dir); Which outputs: string 'f:\link-target' (length=14) string 'F:\link-target' (length=14) Notice the change in case on the second realpath. Is this a bug, or intended? And whats the best way to work around it? It is breaking a case like this: function check_link($to, $from) { if (realpath($to) !== realpath($from)) { ... } } Which is

How to follow a shortcut in powershell

别等时光非礼了梦想. 提交于 2019-12-06 08:13:34
In powershell, you use cd dir to go into the directory dir . But if dir is a shortcut to a directory, cd dir and cd dir.lnk both give an error, saying that the directory doesn't exist. So how do I follow that shortcut? (In Linux cd dir just works . In Windows, I've got no idea) Using the shell com-object, you can get the target path and from there, do what you wish. Get-ShortcutTargetPath function Get-ShortcutTargetPath($fileName) { $sh = New-Object -COM WScript.Shell $targetPath = $sh.CreateShortcut($fileName).TargetPath [System.Runtime.Interopservices.Marshal]::ReleaseComObject($sh) | Out
