Symboldateien

Symboldateien, often referred to as symbolic links or symlinks, are a type of file in Unix-like operating systems that act as a pointer to another file or directory. Instead of containing the actual data of the target file, a symlink contains the path to that target. When an operating system accesses a symlink, it follows the path embedded within the symlink to reach the intended file or directory. This mechanism allows for creating aliases or shortcuts to existing data.

The primary use of symlinks is to provide flexible file system organization. They can be used to make a file or directory appear in multiple locations without duplicating the actual data, saving storage space and simplifying management. For instance, a common application is in software development, where symlinks can point to different versions of libraries or executables, allowing users to switch between them easily. They are also frequently employed in system administration to manage configuration files or to create standardized paths for commonly accessed resources.

Creating a symlink typically involves a specific command, such as `ln -s target_path link_name` on Unix-like systems. The `-s` option explicitly indicates that a symbolic link should be created. It is important to distinguish symlinks from hard links. A hard link is a direct reference to the data on the disk, whereas a symlink is a separate file that contains a path. Deleting the target file of a symlink will result in a broken link, meaning the symlink will no longer point to a valid location.
