Eivind Uggedal 8f4b2e8689 ln: only check existence of src/to for hardlinks
This allows for creating dangling symlinks with force applied:

    # Before:
    $ ln -sf non-existant target
    ln: stat non-existent: No such file or directory
    $ ls -l target
    ls: lstat target: No such file or directory

    # After:
    $ ln -sf non-existant target
    $ ls -l target
    lrwxrwxrwx    1 eu    users   12 May 08 07:50 target -> non-existent

This also allows creating relative non-dangling symlinks with force applied:

    touch existant; mkdir dir

    # Before
    $ ln -sf ../existant dir
    ln: stat ../existant: No such file or directory
    $ ls -l dir

    # After
    $ ln -sf ../existant dir
    $ ls -l dir
    lrwxrwxrwx    1 eu    users   11 May 08 07:53 existant -> ../existant

The check for whether each src and to pairs are on the same device with the
same inode are only needed for hardlinks so that a forcefull link does
not remove the underlying file:

    touch f; mkdir dir

    # Before:
    $ ln -f f f dir
    ln: f and f are the same file
    $ ls -i f dir/f
    3670611 dir/f
    3670611 f

    # After:
    $ ln -f f f dir
    ln: f and f are the same file
    $ ls -i f dir/f
    4332236 dir/f
    4332236 f

sbase - suckless unix tools
===========================

sbase  is a  collection of  unix  tools that  are inherently  portable
across UNIX and UNIX-like systems.

The following tools are implemented:

'#'  -> UTF-8 support, '=' -> Implicit UTF-8 support, '*' -> Finished,
'|'  -> Audited,       'o' -> POSIX 2013 compliant,   'x' -> Non-POSIX,
'()' -> Petty flag

The  complement of  sbase  is  ubase[1] which  is  Linux-specific  and
provides all  the non-portable tools.   Together they are  intended to
form a base system similar to busybox but much smaller and suckless.

Building
--------

To  build sbase,  simply  type  make.  You  may  have  to fiddle  with
config.mk depending on your system.

You  can  also  build  sbase-box,  which  generates  a  single  binary
containing  all  the  required  tools.    You  can  then  symlink  the
individual tools to sbase-box or run: make sbase-box-install

Ideally you will  want to statically link sbase.  If  you are on Linux
we recommend using musl-libc[2].

Portability
-----------

sbase has been  compiled on a variety of  different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.

Various combinations of operating  systems and architectures have also
been built.

You can build sbase with gcc, clang, tcc, nwcc and pcc.
