（TCL /期待）退出后，画面清晰 [英] (Tcl/Expect) clear screen after exit

问题描述

我想从我的（半）互动expect脚本退出后清除屏幕（在本地计算机上）。我能做到这一点从脚本内？这是我尝试过，失败。

I want to clear the screen (on the local machine) after exiting from my (semi) interactive expect script. Can I do that from within the script? Here's what I tried, that failed.

#!/usr/bin/expect -f
set env(TERM) vt100
spawn ssh -Y username@domain
set user username
set pass password 
#login sequence
expect "password: "
send "${pass}\r"
sleep .5  
#some menu commands to enter ERP....
#...
#...
set CTRLZ \032
set CTRLC \003
set CTRLA \001
#don't time out
set timeout -1 
        interact {
                -reset $CTRLZ {exec kill -STOP [pid]}
                $CTRLA   {   
                        exp_send "menucmd...\ry\r"
                }   
                $CTRLC   {  

                        #clear the host machine screen???
                        exec clear
                        exit
                }
                ~~  
        } 

在远程端我不是在shell，但在ERP项目。我可以退出的壳，然后在远程主机上做了一个明确的如果这就是必要的，但我想在远程主机提示仍然会在屏幕上。

On the remote side I'm not in a shell but in an ERP program. I could exit to the shell then do a "clear" on the remote host if that's what's necessary, but I think the remote host prompt would still be on the screen.

编辑：改为尝试退出之前清（子问题：EXEC清除运行脚本期待权的机器上执行）

changed to try clear before "exit" (sub-question: "exec clear" is executed on the machine running the expect script right?)

推荐答案

一旦[退出]，一切之后是不会被执行。你应该[执行清]飞去。

Once you [exit], everything else after is not going to be executed. You should [exec clear] before exiting.

如果您使用的是VT100兼容终端（和大多数Unix终端），那么你可以尝试直接发送VT100命令到终端：

If you're using a vt100 compatible terminal (and most Unix terminals are) then you can try directly sending vt100 commands to the terminal:

puts \033\[2J
