@Glenn对不起！只是道歉,我的意思是！

对不起Glenn您的代码需要进行一些更改,我在这里添加并使其工作.谢谢你！抱歉我的粗鲁.
以下是其他需要它的人的固定代码.您可以将IP放在文本文件中,然后将cat放在servers_addresses中.像servers_addresses =(‘cat ip_list.txt’)
在IP列表中添加IP,如10.10.10.1 10.10.10.2 10.10.10.3

如果需要还有更多例子.
运行命令：

./test.sh "sudo cat /etc/hosts"

运行多个命令

./test.sh "sudo cat /etc/hosts & /etc/init.d/network status"

@L_673_9@和替换

./test.sh "sed -i -e 's/search_string/replaCE_StriNG/g' /tmp/Filename.txt"

完整代码：

#!/bin/bash
    (( $# != 1 )) && { echo >&2 "Usage: $0 \"[COMMAND]\""; exit 1; }
    servers_addresses=( 10.10.10.10 192.168.10.1 )
    for server_address in ${servers_addresses[@]}; do
        expect <<EOF
    set passwds { password1 password2 password3 }
    set i 0
    spawn ssh -t root@$server_address "$*"
    expect {
        "Are you sure you want to conTinue connecTing (yes/no)?" { send "yes\r"; exp_conTinue }
        "s password:" { send "[lindex \$passwds \$i]\r"; incr i; exp_conTinue }
        eof
    }
    EOF
    done

我正在尝试运行此脚本,但在修改时出现了不同的错误.这是代码和输出.请帮忙.

使用调试信息更新帖子的末尾

#!/bin/bash
    (( $# != 1 )) && { echo >&2 "Usage: $0 \"[COMMAND]\""; exit 1; }
    servers_addresses=(10.10.10.10 )
    for server_address in ${servers_addresses[@]}; do
    expect <<EOF
    spawn ssh -t root@$server_address "$*"
    expect -timeout 2 "Are you sure you want to conTinue connecTing (yes/no)?" { send "yes\n" }
    expect "s password:" { send "Correct_password\n" }
    expect "s password:" { send "Wrong_password_22222\n" }
    expect "s password:" { send "Wrong_password_33333\n" }
    expect eof
    EOF
    done

输出如下：

goldberg188@Test-Server ~$./test.sh "sudo cat /etc/hosts"
    spawn ssh -t root@10.10.10.10 sudo cat /etc/hosts
    root@10.10.10.10's password:
    # Do not remove the following line,or varIoUs programs
    # that require network functionality will fail.
    10.10.10.10             TEST-004 localhost.localdomain localhost
    ::1             localhost6.localdomain6 localhost6
    Connection to 10.10.10.10 closed.
    expect: spawn id exp4 not open
        while execuTing
    "expect "s password:" { send "Wrong_password_33333\n" }"

如果我像这样修改,那么输出会有所不同

expect "s password:" { send "Wrong_password_11111\n" }
    expect "s password:" { send "Correct_password\n" }
    expect "s password:" { send "Wrong_password_33333\n" }

    goldberg188@Test-Server ~$./test.sh "sudo cat /etc/hosts"
    spawn ssh -t root@10.10.10.10 sudo cat /etc/hosts
    root@10.10.10.10's password:
    # Do not remove the following line,or varIoUs programs
    # that require network functionality will fail.
    10.10.10.10             TEST-004 localhost.localdomain localhost
    ::1             localhost6.localdomain6 localhost6
    Connection to 10.10.10.10 closed.
    expect: spawn id exp4 not open
        while execuTing
    "expect eof"

如果第三行中的密码正确,则根本没有错误.在这一个工作正常.

expect "s password:" { send "Wrong_password_11111\n" }
    expect "s password:" { send "Wrong_password_22222\n" }
    expect "s password:" { send "Correct_password\n" }


    goldberg188@Test-Server ~$./test.sh "sudo cat /etc/hosts"
    spawn ssh -t root@10.10.10.10 sudo cat /etc/hosts
    root@10.10.10.10's password:
    # Do not remove the following line,or varIoUs programs
    # that require network functionality will fail.
    10.10.10.10             TEST-004 localhost.localdomain localhost
    ::1             localhost6.localdomain6 localhost6
    Connection to 10.10.10.10 closed.

忽略编辑：我知道如何一次运行2个命令.

更新：调试信息 – 修改为

exp_internal 1
    expect "s password:" { send "Wrong_password_11111\n" }
    expect "s password:" { send "Correct_password\n" }
    expect "s password:" { send "Wrong_password_33333\n" }
