スクリプトエラーの送信が予想されます：実行中にスポーンID exp4が開いていません

このスクリプトを実行しようとしていますが、変更すると別のエラーが発生します。これがコードと出力です。助けてください。

デバッグ情報を含む投稿の最後の更新

    #!/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

そして出力は次のようになります：

    goldberg188@Test-Server ~$ ./test.sh "Sudo cat /etc/hosts"
    spawn ssh -t [email protected] Sudo cat /etc/hosts
    [email protected]'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" }"

このように変更すると、出力は少し異なります

    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 [email protected] Sudo cat /etc/hosts
    [email protected]'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"

3行目に正しいパスワードが入力されていれば、エラーはまったくありません。これで問題なく動作します。

    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 [email protected] Sudo cat /etc/hosts
    [email protected]'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.

編集を無視：2つのコマンドを一度に実行する方法を知っています。

意図的に間違ったパスワードを送信していないと想定して、exp_continueをループ構造として：

expect <<EOF
set passwds {foo bar baz}
set i 0
spawn ssh -t root@$server_address "$*"
expect {
    "continue connecting (yes/no)?" { send "yes\r"; exp_continue }
    " password: " { send "[lindex $passwds $i]\r"; incr i; exp_continue }
    eof
}
EOF

クレジット： glenn jackman

申し訳ありませんが、Glennのコードにはいくつかの変更が必要ですが、ここに追加して機能させます。

これは、それを必要とする可能性のある他の人のための固定コードです。 IPをテキストファイルに入れて、servers_addresses内にcatできます。同様にservers_addresses =（ 'cat ip_list.txt'）

IPリストに次のようなIPを追加します10.10.10.1 10.10.10.2 10.10.10.3

必要に応じて、さらに例を示します。コマンドを実行します。

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

複数のコマンドを実行する

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

検索と置換

    ./test.sh "sed -i -e 's/SEARCH_STRING/REPLACE_STRING/g' /tmp/FileNAME.txt"

完全なコード：

    #!/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
