tcl - how to execute a command for multiple occurrance and change the variable from list each time

Question

I have a list which contains 72.xx.xxx.xxx 72.xx.xxx.xxx (There are some spaces ) I have a variable say var

Now I have to execute a command for $var times and I have to use "72.xx.xxx.xxx" each time. let us say the command is : "reset vpn $IP".

I have to execute the above command say two times (stored in variable) and for two IP address stored in list. Can any one help with TCL code? Thanks in advance.

这真的是一个家庭作业。并且任务规范缺少一些重要的细节。

如果要遍历列表中的所有IP，只需执行

set ips {72.xx.xxx.xxx 72.xx.xxx.xxx}
foreach ip $ips {
  reset vpn $ip
}

如果您向ips列表中添加更多值，则该foreach命令将对所有剩余元素进行更多次迭代。

如果你想迭代，比如说，前 N 个元素，只需一个一个地选择它们：

set ips {72.xx.xxx.xxx 72.xx.xxx.xxx 72.xx.xxx.xxx 72.xx.xxx.xxx ...}
set ntimes 2
for {set ix 0} {$ix < $ntimes} {incr ix} {
  reset vpn [lindex $ips $ix]
}

等等。

没有火箭科学。只需阅读教程，阅读本书，在您真正尝试自己之前，请尽量避免提出这些简单的问题。
