+`test` implements a subset of the <a href="http://www.unix.com/man-page/POSIX/1/test/">IEEE Std 1003.1-2008 (POSIX.1) standard</a>. The following exceptions apply:
 - The `<` and `>` operators for comparing strings are not implemented.
 - Because this test is a shell builtin and not a standalone utility, using the -c flag on a special file descriptors like standard input and output may not return the same result when invoked from within a pipe as one would expect when invoking the `test` utility in another shell.
  In cases such as this, one can use `command` `test` to explicitly use the system's standalone `test` rather than this `builtin` `test`.
