问下ns2的这些命令应该写在哪里面？我用的ubuntu，是ubuntu终端？……

下面是ns2的Tcl程序，这些代码应该写在哪里面？ubuntu的终端？我在终端里输入前三条命令还通过，第四条就提示duplex-link：找不到命令？
set ns [new Simulator]
set n1 [$ns node]
set n2 [$ns node]
$ns duplex-link $n1 $n2 1Mb 1ms DropTail
set udp [new Agent/UDP]
$ns attach-agent $n1 $udp
set cbr [new Application/Traffic/CBR]
$cbr attach-agent $udp
set nul [new Agent/Null]
$ns attach-agent $n2 $nul
$ns connect $udp $nul
$ns at 0.0 "$cbr start“
$ns at 2.0 "exit 0“
$ns run

建一tcl文件...然后在terminal里面打ns 文件名.tcl
