If you are okay with (or want) to kill the command that's taking too long then eval+alarm may be what you are looking for. Maybe this code will give you some ideas: 
sub cmd_wrapper {
    my $timeout = shift;
    my $cmd     = shift;
    my( $out, $rc );
    
    eval { 
        local $SIG{ALRM} = sub { die "alarm\n" };
        alarm $timeout;
        $out = (`$cmd`)[0]; # Get first line of output
        $rc = $?;
        alarm 0;
    };
    
    if( $@ ) {
        die "Eval failed for $cmd for unknown/unexpected reasons" if $
+@ ne "alarm\n"; 
        die "Eval failed for $cmd because alarm timed out";
    }
    die "Return code undefined for $cmd" unless defined $rc;
    return $rc, $out if wantarray;
    return $rc;
}

my $rc = cmd_wrapper(300, $pull_cmd); # Will timeout in 5 minutes (300
+ seconds)
