In the example below, I copied a statistics file from an active run to a new file, which deleted all of its contents:</div><div><br></div><div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> du -sh bkb1Ra1e5/output_bkb1Ra1e5/statistics</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>5.1M<span class="Apple-tab-span" style="white-space:pre"> </span>bkb1Ra1e5/output_bkb1Ra1e5/statistics</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> cp bkb1Ra1e5/output_bkb1Ra1e5/statistics stat</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> du -sh bkb1Ra1e5/output_bkb1Ra1e5/statistics</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>0<span class="Apple-tab-span" style="white-space:pre"> </span>bkb1Ra1e5/output_bkb1Ra1e5/statistics</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> </font></div></div><div><div><br></div></div><div>The copy of the statistics file also has no contents:</div><div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> du -sh stat</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>0<span class="Apple-tab-span" style="white-space:pre"> </span>stat</font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> </font></div></div><div><br></div><div>The same thing has definitely happened when I've open a statistics file with vi from an active model. </div><div><br></div><div>Doing "du -sh" within the same folder as the statistics file may also erase the contents:</div><div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>naliboff >> du -sh output_bkb1Ra1e5/statistics </font></div><div><font class="Apple-style-span" color="#ff271f"><span class="Apple-tab-span" style="white-space:pre"> </span>0<span class="Apple-tab-span" style="white-space:pre"> </span>output_bkb1Ra1e5/statistics</font></div></div><div>In the above case, at least, I don't remember going into the output folder prior to this morning, but another nefarious unix command may have killed the statistics file and I just don't remember.</div><div><br></div><div>Anyhow, I guess one solution to this problem is to not do any operation on the statistics file until the model is done running.</div><div><br></div><div>However, often times I want to plot some of the values within the statistics file during a run. In that case, is there a way around the apparent sensitivity of the statistics file to various unix commands?</div><div><br></div><div>I guess another question is whether this issue is specific to the cluster I'm running aspect on at Davis.</div><div><br></div><div>Cheers,</div><div>John</div><div><div><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><br></div><br class="Apple-interchange-newline"></div>
