The exceptions are those which may create binary netCDF grid files such as <A NAME="tex2html1124" HREF="../man/surface.html"><I><B>surface</B></I></A><A NAME="18708"></A> (due to the design of netCDF a filename must be provided; however, alternative binary output formats allowing piping are available; see Section <A HREF="node71.html#sec:grdformats">4.17</A>). With <I>UNIX</I> you can redirect standard output to a file or pipe it into another process. Error messages, usage messages, and verbose comments are written to standard error in all cases. You can use <I>UNIX</I> to redirect standard error as well, if you want to create a log file of what you are doing. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html3380" HREF="node62.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="next.png"></A> <A NAME="tex2html3374" HREF="node30.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="up.png"></A> <A NAME="tex2html3368" HREF="node60.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="prev.png"></A> <A NAME="tex2html3376" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="contents.png"></A> <A NAME="tex2html3378" HREF="node255.html"> <IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="index.png"></A> <BR> <B> Next:</B> <A NAME="tex2html3381" HREF="node62.html">4.10 Input data formats</A> <B> Up:</B> <A NAME="tex2html3375" HREF="node30.html">4.
