readlink is not a standard command, but it’s common on Linux and BSD, including OS X, and it’s the most straightforward answer to your question. BSD and GNU readlink implementations are different, so read the documentation for the one you have. If readlink is not available, or you need to write a cross-platform script that … Read more
Have a look at the following config option from nginx docs: Syntax: disable_symlinks off; disable_symlinks on | if_not_owner [from=part]; Default: disable_symlinks off; Context: http, server, location This directive appeared in version 1.1.15.
private bool IsSymbolic(string path) { FileInfo pathInfo = new FileInfo(path); return pathInfo.Attributes.HasFlag(FileAttributes.ReparsePoint); }
NTFS file system has junction points, I think you may use them instead, You can use python win32 API module for that e.g. import win32file win32file.CreateSymbolicLink(fileSrc, fileTarget, 1) If you do not want to rely on win32API module, you can always use ctypes and directly call CreateSymbolicLink win32 API e.g. import ctypes kdll = ctypes.windll.LoadLibrary(“kernel32.dll”) … Read more
My very personal trick for files (not directories): sed -i ” **/* Note that I’m using ** which uses the bash globstar option, you may have to enable it beforehand: shopt -s globstar How it works I trick sed to do the job, by using an implementation detail of the sed inplace mode. sed is … Read more
Thanks to Andy Skelton, it appears the answer is readlink -f: $:/tmp/symtest$ readlink -f /tmp/symtest/foo/bar/cat /tmp/symtest/cat
Try this: function Test-ReparsePoint([string]$path) { $file = Get-Item $path -Force -ea SilentlyContinue return [bool]($file.Attributes -band [IO.FileAttributes]::ReparsePoint) } It is a pretty minimal implementation, but it should do the trick. Note that this doesn’t distinguish between a hard link and a symbolic link. Underneath, they both just take advantage of NTFS reparse points, IIRC.
I think readlink is what you are looking for: File.readlink(“path/to/symlink”)
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 the documentation … Read more
