Hi there,
I have got the example of trailing a file from "Perl Cookbook":
-----------
for (;;) {
while (<FH>) { print $_ }
sleep 1;
seek(FH, 0, 1);
}
-----------
However, if another program removes (all) lines from the file referenced by
FH, perl looses the trailing (for a undetermined time). How do I improve
this code to understand the file was changed?
Cheers,
Bruno
