For PLplot I have implemented a fairly complex bash script that runs<br>
through a large series of tasks to do comprehensive testing of PLplot.<br>
The script calls its own special exit function whenever the script logic says<br>
it is time to exit, and that function among other tasks collects a<br>
convenient report tarball of carefully selected test results which makes<br>
it much easier for me to diagnose any PLplot problems that occur<br>
during the comprehensive testing.<br>
<br>
So far so good, but sometimes this script just hangs (e.g., on<br>
platforms which have buggy parallel builds such as MSYS and MSYS2) so<br>
the user has to interrupt it to get it to exit. Can bash logic<br>
intercept such user interruptions and force exiting via the special<br>
exit function?<br>
<br>
One PLplot tester has just run into this problem so he has attempted<br>
to compensate by collecting all the useful bits and pieces by hand in<br>
a tarball. But the results would be more reliable and also more<br>
convenient for him, if the script could automatically do that when it<br>
was interrupted.<br>

Never mind. I haven't tried it yet, but there is a straightforward<br>
example of bash interrupt handling at<br>

which assuming it works should solve the above issue.<span class="HOEnZb"><font color="#888888"><br>
