<pre class="moz-quote-pre" wrap="">cdfdiff and ncmpidiff were designed to be more like unix command “diff”.
It reports whether the 2 NetCDF files are different and the “locations”
of differences.

FYI. I updated cdfdiff to report the array indices of first
array element that is found different
....
Command line option -b is for verbose mode, which also reports
what objects are the same.</pre>

Wei-keng -- I'm still trying to work with the sources that I ported
before you made more of the "diff" changes.<br>
This output here, is it only telling me that the arrays are not
identical?<br>

I'm trying to figure out "how different" the two files are.<br>
Can you tell me what the <tt>(1)</tt> & <tt>(-1)</tt> refer
to?<br>
If I use the "<tt>-b</tt>" option, I get the extra output about the
sizings of the arrays, for example<br>
<blockquote><tt>Variable "wwAvg_split":</tt><br>
<tt> SAME: data type (float)</tt><br>
<tt> SAME: number of dimensions (3)</tt><br>
<tt> dimension 0:</tt><br>
<tt> SAME: name (Time)</tt><br>
<tt> SAME: length (2)</tt><br>
<tt> dimension 1:</tt><br>
<tt> SAME: name (nCells)</tt><br>
<tt> SAME: length (40962)</tt><br>
<tt> dimension 2:</tt><br>
<tt> SAME: name (nVertLevelsP1)</tt><br>
<tt> SAME: length (57)</tt><br>
<tt> SAME: number of attributes (2)</tt><br>
<tt> attribute "units":</tt><br>
<tt> SAME: data type (char)</tt><br>
<tt> SAME: length (16)</tt><br>
<tt> SAME: attribute contents</tt><br>
<tt> attribute "long_name":</tt><br>
<tt> SAME: data type (char)</tt><br>
<tt> SAME: length (51)</tt><br>
<tt> SAME: attribute contents</tt><br>

but the difference in the content is still reported the same as
above.<br>
