Usage: 

ln [OPTION]... [-T] TARGET LINK_NAME  (1st form)

or:  ln [OPTION]... TARGET                  (2nd form)

or:  ln [OPTION]... TARGET... DIRECTORY    (3rd form)

or:  ln [OPTION]... -t DIRECTORY TARGET...  (4th form)

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.

Mandatory arguments to long options are mandatory for short options too.

--backup[=CONTROL]      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

--version  output version information and exit
