On the topic of FHs, I have a CGI script that opens a file handle and then
in the HTML code I print out the results -
open(FH, "grep blahblah /usr/local/apache/log |");
print "<html>\n";
etc..
while <FH>{
print "$_ <br>";
}
etc..
print "</html>";
Now my problem is how do I time out the grep command?? Sometimes one of the
files that it runs against takes forever to mount (automount). Also the logs
are so big that grep runs forever - is there anyway to stop it, besides
getting on the box and killing the PID?

The two major ones I can think of off the top of my head is if the disk
fills up or you are writing to a file on a network disk and the connection
goes goes down. In both circumstances your data was lost and you would want
to know about it. There are many others.
