The phrase resolving a link means to substitute the actual location in the file system for the symbolic link. ![]() Reading or writing to a symbolic link is the same as reading or writing to any other file or directory. HomeLogFile is the target of the link.Ī symbolic link is usually transparent to the user. In the following figure, logFile appears to be a regular file to the user, but it is actually a symbolic link to dir/logs/HomeLogFile. (The file or directory being pointed to is called the target of the link.) Exceptions are when a symbolic link is deleted, or renamed in which case the link itself is deleted, or renamed and not the target of the link. For the most part, symbolic links are transparent to applications, and operations on symbolic links are automatically redirected to the target of the link. A symbolic link is also referred to as a symlink or a soft link.Ī symbolic link is a special file that serves as a reference to another file. But some file systems also support the notion of symbolic links. Symbolic Linksįile system objects are most typically directories or files. Without more information, a program cannot reliably locate the joe/foo directory in the file system. All of the information needed to locate the file is contained in the path string.Ī relative path needs to be combined with another path in order to access a file. For example, /home/sally/statusReport is an absolute path. An absolute path always contains the root element and the complete directory list required to locate the file. Relative or Absolute?Ī path is either relative or absolute. The character used to separate the directory names (also called the delimiter) is specific to the file system: The Solaris OS uses the forward slash ( /), and Microsoft Windows uses the backslash slash ( \). For example, the statusReport file in the previous figure is described by the following notation in the Solaris OS: The Solaris OS supports a single root node, which is denoted by the slash character, /.Ī file is identified by its path through the file system, beginning from the root node. Each root node maps to a volume, such as C:\ or D:\. Microsoft Windows supports multiple root nodes. The following figure shows a sample directory tree containing a single root node. Each directory can contain files and subdirectories, which in turn can contain files and subdirectories, and so on, potentially to an almost limitless depth. Under the root node, there are files and directories ( folders in Microsoft Windows). At the top of the tree is one (or more) root nodes. Most file systems in use today store the files in a tree (or hierarchical) structure. A file system stores and organizes files on some form of media, generally one or more hard drives, in such a way that they can be easily retrieved.
