The term "soft link" is used in computer science to describe a symbolic or indirect connection between files or directories. Its spelling is based on the English language's phonetic rules, with "soft" pronounced as /sɒft/ and "link" pronounced as /lɪŋk/. The first syllable of "soft" takes the short "o" sound while the "i" in "link" follows the short "i" sound. Together, the two words form a compound noun that accurately represents the nature of their connection within the computer system.
A soft link, also known as a symbolic link or symlink, is a type of file that points to another file or directory in a computer's file system. It acts as a virtual reference, allowing users to create a shortcut or alias for a file or directory, without creating a physical copy or duplicating the original data. Soft links are typically created within the same file system, allowing users to access files or directories located elsewhere on their system without having to navigate through complex directory structures.
Unlike hard links, soft links are more flexible as they can point to files or directories on different file systems. This means that even if the original file or directory is moved or renamed, the soft link will still direct users to the correct location. Soft links preserve the original file permissions and attributes, ensuring that when accessed through the link, the same level of access and functionality is maintained.
In a graphical user interface (GUI) environment, soft links are often represented by an icon that has an arrow or a shortcut symbol, indicating that it is a reference rather than the actual file. Soft links are widely used in operating systems such as Unix, Linux, and macOS to create convenient shortcuts, enhance system organization, and streamline access to files and directories. They provide a means for users to navigate the file system efficiently and save disk space by avoiding unnecessary duplication of data.
The term "soft link" originated in the context of computer science and is commonly used as a synonym for a symbolic link or symlink. The word "soft" in this context refers to the fact that it is a non-permanent or flexible link.
The term "symbolic link" was first introduced in the early 1970s with the development of the Unix operating system. It was created as a means to reference or link to another file or directory within the file system, without creating a physical copy of the actual file.
The term "soft link" emerged as an alternative term to "symbolic link", and it emphasizes the idea that the link is not a physical or direct connection, but rather a symbolic representation of the target file or directory. This distinction was established to differentiate it from a "hard link" which is a direct reference to the physical location of the file.
