ln(1) - make links between files
In  the  1st  form,  create  a link to TARGET with the name LINK_NAME.  In the 2nd form, create a link to
TARGET in the current directory.  In the 3rd and 4th forms, create links to  each  TARGET  in  DIRECTORY.
Create hard links by default, symbolic links with --symbolic.  When creating hard links, each TARGET must
exist.  Symbolic links can hold arbitrary text; if later resolved, a  relative  link  is  interpreted  in
relation to its parent directory.
       make a backup of each existing destination file
-b     like --backup but does not accept an argument
-d, -F, --directory
       allow  the  superuser  to attempt to hard link directories (note: will probably fail due to system
       restrictions, even for the superuser)
-f, --force
       remove existing destination files
-i, --interactive
       prompt whether to remove destinations
-L, --logical
       make hard links to symbolic link references
-n, --no-dereference
       treat destination that is a symlink to a directory as if it were a normal file
-P, --physical
       make hard links directly to symbolic links
-s, --symbolic
       make symbolic links instead of hard links
-S, --suffix=SUFFIX
       override the usual backup suffix
-t, --target-directory=DIRECTORY
       specify the DIRECTORY in which to create the links
-T, --no-target-directory
       treat LINK_NAME as a normal file
-v, --verbose
       print name of each linked file
--help display this help and exit
       output version information and exit
