       realpath - return the canonicalised absolute pathname


       realpath [-s|--strip] [-z|--zero]  filename  ...
       realpath --h|--help
       realpath --v|--version


       realpath  converts each filename argument to an absolute pathname, which has no components
       that are symbolic links or the special .  or ..  directory entries.  (See realpath(3)  for
       more information.)
       Each  path component in the filename must exist, otherwise realpath will fail and non-zero
       exit status will be returned.
       Please note that mostly the same functionality is provided by  the  `-e'   option  of  the
       readlink(1) command.

       When  the  -s  option  is  used  realpath only removes the .  and ..  directories, but not
       symbolic links from filename.  If the given filename argument is relative (i.e.  does  not
       start  with  `/'),  realpath -s prepends to it the current directory name as obtained from
       the getcwd(2) system call before further processing.

       Each converted pathname is output to the standard output, on its own line.


       -s, --strip
            Only strip .  and .., components, but do not resolve symbolic links.

       -z, --zero
            Separate output filenames with the null character instead of newline, so  it  can  be
            used with the `-0' option of xargs(1).

       -h, --help
            Print short usage information.

       -v, --version
            Show realpath's version number.


       For  the  examples  below  let's suppose that /usr/bin/X11 is a symbolic link, pointing to
       directory /usr/bin.

   Example 1
       Regardless of what the current directory is
           realpath /../usr/bin/X11/./xterm
           realpath -s /../usr/bin/X11/./xterm

   Example 2
       When the current directory is /usr/bin/X11 (which is still a symbolic link  to  /usr/bin),
       the output of both
           realpath ./xterm
           realpath  -s ./xterm
       will be

   Example 3
       Providing  that  the  current directory is /home/user (and the directory exists before and
       during the realpath run), the  command
           realpath ../path/to/some/./non-existent/./directory/../or/../file
       will fail with the following error
           ../path/to/some/./non-existent/./directory/../or/../file: No such file or directory
           realpath -s ../path/to/some/./non-existent/./directory/../or/../file
       will return


       realpath returns a zero exit code when all pathnames were successfully converted.
       In case of any errors (e.g. missing or unavailable  directories  in  the  path),  realpath
       prints error message to stderr and returns a non-zero exit code.


       basename(1), dirname(1), readlink(1), chase(1), realpath(3)


       Hopefully none :)
