unix_s
======

shell (sh) command execution, no output



Calling Sequence
~~~~~~~~~~~~~~~~


::

    unix_s(cmd)




Arguments
~~~~~~~~~

:cmd a character string
:



Description
~~~~~~~~~~~

Sends a string `cmd` to Unix for execution by the sh shell. The
standard output is redirected to /dev/null. Unix execution errors are
trapped; *NOTE* that only the last shell command error is reported
when a list of command separated by ";" is sent: this is not
recommended.



Examples
~~~~~~~~


::

    if `getos`_() == 'Windows' then 
      unix_s("del foo");
    else 
      unix_s("rm -f foo"); 
    end
