ln

LN(1)							      General Commands Manual							     LN(1)

NAME

       ln, clone - create a link to a file

SYNOPSIS

       ln [-ifmrRvx] file [name]
       ln [-ifrRvx] file ... dir
       clone [-ifmvx] file [name]

OPTIONS

       -i     Ask if ok to remove a file

       -f     Remove existing links

       -m     Merge trees, disable the into-a-directory trick

       -rR    Recursively link a directory tree

       -v     Display what ln is doing

       -x     Do not cross device boundaries

EXAMPLES

       ln file newname	   # Make newname a synonym for file

       ln /usr/games/chess # Create a link called chess

DESCRIPTION

       A directory entry is created for name .	The entry points to file .  Henceforth, name and file can be used interchangeably.  If name is not
       supplied, the last component of file is used as the link name.  If more than one file is supplied or the name refers to an existing  direc-
       tory, links will be created in that directory.  An existing name will not be removed unless the -i or -f flag is specified.

       Clone is a convenient synonym for ln -fmr to create a so-called "link farm", a directory full of links to the original tree.

SEE ALSO

       cp(1), link(2), unlink(2).
