BenBart> How do I prevent multiple instance of the same script from running?
Use the "highlander" solution:
#!/usr/bin/perl
BEGIN {
use Fcntl ':flock';
flock DATA, LOCK_EX | LOCK_NB or exit 0; # I'm already running
}
[ rest of your script here ]
__END__
To do this, you must have __END__ at the end of your script, or else DATA
is not opened.
