Yes. Here's an example of some code I use that does this (but alarm, as I've heard, may be unsafe in older Perls):

#!/usr/bin/perl
use strict;
use warnings;

my $timeout = 180;
my @array = (
        "command 1 goes here",
        "command 2 goes here",
        "command 3 goes here",
        );

for (@array) {
eval {
    local $SIG{ALRM} = sub {
        die "alarm\n";
    };
    alarm $timeout;
    system($_);
    alarm 0;
};
