如何在使用期望“发送"的同时将输出存储在变量中.命令. [英] How to store output in a variable , while using expect "send" command.

问题描述

大家好，
我在使用send in Expect(tcl)时遇到了一些问题.
问题:
1.在linux机器上，我正在运行一些refelct:使用
获取我所有反射进程的进程ID. ps -aef | grep反映| grep -v grep | awk''{print $ 2}''
将会返回类似

2.我想在pf Expect的帮助下做同样的事情，这是我的代码

Hi all,
i am facing some problem while using send in expect (tcl).
problem:
1. in linux machine i am running some process refelct: for getting the process id of all the reflect processes i m using
ps -aef | grep reflect | grep -v grep | awk ''{print $2}''
which will return something like

19768
19546
10465

2. same thing i want to do with the help pf expect , here is my code

proc monitor_server {ip_server} {
	source "/cygdrive/e/ncp/pat/pat_config.exp"
	set cmd1 {ps -aef | grep reflect | grep -v grep | awk ''{print $2}''}
	if {[catch { spawn ssh $ip_server -l root } res]} {
			puts $res
			return 0
		} else {
			expect -re "(yes/no)"
			send "yes\r"
			sleep 1
			expect -re "root@$ip_server''s password: " 
			send "$passwd_testbed\r"
			expect -re ".*# " {
				send " $cmd1 \r"
				expect -re "/\d\n" 
				puts $expect_out(0,string)
			}		}
}

该代码正在执行命令，但是当命令执行时，我想将输出放入变量$ expect_out(0，string).
可能是我需要某种模式匹配，还是在发送$ cmd时获得某种变量的结果(我的意思是命令的结果).
因为我是tcl的新手，并且期待. 在此先感谢

this code is working up to executing the command, but when the command is getting executed , i want to get the out put in variable $expect_out(0,string).
may be i need some kind on pattern matching for that or is there any other way to get the result in some variable while i send the $cmd (i mean result of the command).
as i am new to tcl and expect.
thanks in advance
tanuj
