Any number of links can be assigned to a file. The number of links does not affect other file attributes such as size, protections, data, etc. If linkname is omitted, the last component of filename is used as the name of the link. Hard links can only be made to existing files. A symbolic link, made with the -s option, is a special directory entry that points to another named file.
Symbolic links can span file systems and point to directories.
A symbolic link to a directory behaves differently than you might expect in certain cases. This means that the parent of the new working directory is not the parent of the symbolic link, but rather, the parent of the pointed-to directory. If the linkname is an existing file and its mode does not forbid writing, then its contents are des- troyed. If however its mode does not allow writing, the mode is printed, and the user asked for a response. Create a symbolic link or links.
