In computing, a symbolic link (also symlink or soft link) is a file whose purpose is to point to a file or directory (called the "target") by specifying a path thereto. [1] Symbolic links are supported by POSIX and by most Unix-like operating systems, such as FreeBSD, Linux, and macOS.
The ln command is a standard Unix command utility used to create a hard link or a symbolic link (symlink) to an existing file or directory. [1] The use of a hard link allows multiple filenames to be associated with the same file since a hard link points to the inode of a given file, the data of which is stored on disk.
A symbolic link is a reference to another file. This special file is stored as a textual representation of the referenced file's path (which means the destination may be a relative path, or may not exist at all). A symbolic link is marked with an l (lower case L) as the first letter of the mode string, e.g. in this abbreviated ls -l output: [5]
Symbolic links are reparse points which operate similarly to Junction Points, or symbolic links in Unix or Linux, and accept relative paths and paths to files as well as directories. Support for directory and UNC paths were added in NTFS 3.1.
Symbolic link: Points to a hard link, not the file data itself; hence, it works across volumes and file systems. NTFS links: Details the four link types that the NTFS supports—hard links, symbolic links, junction points, and volume mount points; Shortcut: A small file that points to another in a local or remote location
The link utility is a Unix command line program that creates a hard link from an existing directory entry to a ... it can create both hard links and symbolic links, ...
Using weak symbols in static libraries has other semantics than in shared ones, i.e. with a static library the symbol lookup stops at the first symbol – even if it is just weak and an object file with a strong symbol is also included in the library archive. On Linux, the linker option --whole-archive changes that behavior. [10]
BSD also added symbolic links (often termed "symlinks") to the range of file types, which are files that refer to other files, and complement hard links. [3] Symlinks were modeled after a similar feature in Multics, [4] and differ from hard links in that they may span filesystems and that their existence is independent of the target object ...
