What is a symbolic link in Linux?

A symbolic link in Linux is essentially a pointer to another file or directory. This feature allows users to create references that act like shortcuts, directing the operating system to another location in the filesystem. When a symbolic link is accessed, the system follows this reference to reach the target file or directory. This capability is beneficial for organizing files, enabling easier access, or maintaining compatibility when the actual location of a file or directory might change.

In practical terms, symbolic links can help create a more manageable and user-friendly structure within a file system. For instance, if a program or script relies on a specific file location, a symbolic link can be created to point to the actual location, ensuring that the program continues to function correctly even if the location changes.

Understanding that a symbolic link serves as a reference rather than a duplicate or a copy of the original data is key to leveraging this feature effectively in Linux.
