Hi

I'm using this to start a tail -f like window on Win to visualize logged output of a background process 

sub start_ps_tail {
    my ( $logfile ) = @_ ;

    print system <<"__CMD__";
    start "MONITORING $logfile" cmd /c powershell gc -tail 10 -wait $l
+ogfile
__CMD__

}

problem is I need to be able to kill the sub-process again when the logfile stopped being open for writing (i.e. isn't locked anymore)

I though about sending a 'kill', but Perl doesn't seem to give me the PID.

My workaround for the time being is to rename the logfile, b/c powerhell will terminate the tail then, but my boss doesn't want that (though I could rename it back)

Any better ideas, there must be a way to kill a sub-process...
