Thanks!
The content of a symbolic link is a string. When the symbolic link is encountered while traversing a pathname, you will get an error if that string (when incorporated into the pathname being evaluated) doesn't resolve to a file of the type expected for the operation being performed. There is no requirement that the contents of the symbolic link can be used to access a file at the time the symbolic link is created.

If a symbolic link is not used in pathname expansion, you can use use readlink() (the function), readlink (the utility [not available on all systems]), or ls (the utility with the -l option), to read the contents of the symbolic link when it is not being used for its normal purpose.

ln(1)							      General Commands Manual							     ln(1)

Name
       ln - link to a file

Syntax
       ln [ -f ] [ -i ] [ -s ] name1 [name2]
       ln [ -f ] [ -i ] [ -s ] name ... directory

Description
       A  link is a directory entry referring to a file.  A file, together with its size and all its protection information may have several links
       to it.  There are two kinds of links: hard links and symbolic links.

       By default makes hard links.  A hard link to a file is indistinguishable from the original directory entry.  Any  changes  to  a  file  are
       effective independent of the name used to reference the file.  Hard links may not span file systems and may not refer to directories.

       Given  one or two arguments, creates a link to an existing file name1.  If name2 is given, the link has that name.  The name2 may also be a
       directory in which to place the link.  Otherwise it is placed in the current directory.	If only the directory is specified,  the  link	is
       made to the last component of name1.

       Given  more  than two arguments, makes links to all the named files in the named directory.  The links made have the same name as the files
       being linked to.

Options
       -f   Forces existing destination pathnames to be removed before linking without prompting for confirmation.

       -i   Write a prompt to standard output requesting information for each link that would overwrite an existing file.  If  the  response  from
	    standard input is affirmative, and if permissions allow, the link is done. The -i option has this effect even if the standard input is
	    not a terminal.

       -s   Creates a symbolic link.

	    A symbolic link contains the name of the file to which it is linked.  The referenced file is used when an operation  is  performed	on
	    the  link.	 A  on a symbolic link returns the linked-to file.  An must be done to obtain information about the link.  The call may be
	    used to read the contents of a symbolic link.  Symbolic links may span file systems and may refer to directories.
