当界面要求时，如何使用Shell脚本提供密码 [英] how to use a shell script to supply a password when the interface asks for it

问题描述

我有一个脚本( dobrt )，该脚本在执行时会要求输入密码.我该如何编写一个执行 dobrt 并自动提供密码要求.

I have a script(dobrt) which upon executing asks for a password.How can i write a script which executes dobrt and automatically supplies the password it asks for.

当我执行./dobrt -p file.txt时，系统要求输入密码.我希望密码由脚本自动发送.这是输出

when i execute ./dobrt -p file.txt , the system asks for a password. I want the password to be sent in automatically by the script. Here is the output

$ ./dobrt -p file.txt
Found 194 tests to execute
------------ 2010 February 11 11:27:33 ------------
Password: *************** 

我尝试为此使用shell和expecxt脚本.这就是我所做的.

I tried using shell and expecxt scripts for this. here is what i did.

我有2个脚本.我从第一个脚本(run_dobrt.sh)调用第二个脚本(run_dobrt.exp).

I have 2 scripts. I call the second script(run_dobrt.exp) from the first one(run_dobrt.sh).

脚本1:run_dobrt.sh

#!/bin/ksh

TESTCASE_HOME="/home/abhijeet/code/testcases";
TESTCASE_LIST="file.txt";
PASSWORD="*****";

echo "Running Expect Script"
`./run_dobrt.exp $TESTCASE_HOME $TESTCASE_LIST $PASSWORD`

脚本2:run_dobrt.exp

#!/usr/local/bin/expect -f
set TESTCASE_HOME [lindex $argv 0];
set TESTCASE_LIST [lindex $argv 1];
set PASSWORD [lindex $argv 3];

set timeout 200
spawn $TESTCASE_HOME/dobrt -p $TESTCASE_HOME/$TESTCASE_LIST
expect "*?assword:*" {send -- "$PASSWORD\r";}
expect eof

现在，当我运行run_dobrt.sh时，出现以下错误 run_dobrt.sh [20]:产生:未找到 如何摆脱这个错误并完成这项任务?请帮忙.

Now when i run run_dobrt.sh i get the following error run_dobrt.sh[20]: spawn: not found How to get rid of this error and get this task done? Please help.

推荐答案

我看到两个问题:

1. 在shell脚本的最后一行中，删除命令周围的反引号`` 它们将导致Expect脚本的输出作为Shell命令执行.

2. 在Expect脚本中，更改

1. In the last line of your shell script, remove the back-quotes `` around the command, they will cause the output of the expect script to be executed as a shell command.

2. In the expect script, change

设置密码[lindex $ argv 3]；

set PASSWORD [lindex $argv 3];

到

set PASSWORD [lindex $argv 2]; 

您正在跳过一个论点.
