Not a very clear question. If you need to check whether
something completes then have the code write out a pidfile
when it starts and unlink it on the way out. A second
process can check for the pidfile at a later time; if the
file is present then check for the process still running.
If the process croaks before the unlink you will find a
pidfile that contains a non-running process [leaving out
the rather unlikely case that your pid's wrap].
e.g.,
#!/usr/bin/perl
my $pidfile = $rundir . '/' . basename $0;
open my $pidfh, '>', $pidfile
or croak "$pidfile: $!";
print $pidfh "$$\n";
close $pidfh;
# do things...
unlink $pidfile
or croak "unlink $pidfile: $!";
-
__END__
A second process can then look for the pidfile (e.g., /var/run/blah.pid),
open it and scream for help if the file is present and the pid doesn't
refer to a running process.
You are nearly always better off having the process that ran
whatever the sql is checking for itself, however, since any
external method runs into various logic races rather quickly.
enjoi.
