What symlink means?
A symbolic link, also termed a soft link, is a special kind of file that points to another file, much like a shortcut in Windows or a Macintosh alias. Unlike a hard link, a symbolic link does not contain the data in the target file. It simply points to another entry somewhere in the file system.
What does a symlink contain?
A symbolic link contains a text string that is automatically interpreted and followed by the operating system as a path to another file or directory. This other file or directory is called the “target”. The symbolic link is a second file that exists independently of its target.
How do I unlink a symlink?
To remove a symbolic link, use either the rm or unlink command followed by the name of the symlink as an argument. When removing a symbolic link that points to a directory do not append a trailing slash to the symlink name.
Does deleting symlink Delete file?
Deleting a symbolic link is the same as removing a real file or directory. ls -l command shows all links with second column value 1 and the link points to original file. Link contains the path for original file and not the contents.
Do symbolic links take up space?
Symbolic links do take room, of course, but just the room it takes to store the name and target plus a few bytes for other metadata. The space taken by a symbolic link does not depend on the space taken by the target (after all, the target is not even required to exist).
What is the use of symlink?

Why do we need symlink?
Why use symbolic links? You can operate on symlinks as if they were the actual files to which they pointing somewhere down the line (except deleting them). This allows you to have multiple “access points” to a file, without having excess copies (that remain up to date, since they always access the same file).
Does rm follow symbolic links?
