Bash foreach循环中expect异常处理的问题

我有一个expect脚本，可以在远程设备上启动命令，有些设备可能存在凭据问题，如果输入密码后重复密码提示，我需要跳过这些问题

    #!/usr/bin/expect -f
    
    set x [list 192.168.1.1 192.168.1.2]
    
    foreach hosts $x {
    # spawn ssh sy-nep-oss@$x
    sleep 5
    spawn ssh  -o StrictHostKeyChecking=no  sy-nep-oss@$hosts
    sleep 5
   
    **expect {"password: "
    send -- "abcd\r"
   
    expect "*>"

如果密码不正确，则需要跳过此循环迭代并转到列表中的下一项

    send -- "cd cfcard:/ \r"
    sleep 2
    expect "*>"
    send -- "cd cfcard2:/ \r"
    sleep 2
    expect "*>"
    sleep 2
    send -- "dir log* \r"
    expect "*>"
    sleep 2
    send "cd log \r"
    expect {enter code here
      "Error: Wrong path *" {
        send "cd logfile \r"
      }
      "logfile*" {
        send "cd log \r"
      }
    }
    expect "*>"
    sleep 2
    send -- "dir log.log \r"
    expect "*>"
    sleep 2
    send -- "system-view \r"
    expect "Enter system view*"
    sleep 2
    send -- "sftp 212.72.10.182 \r"
    expect  "*username*"
    sleep 2
    send -- "test\r"
    expect  "*password:"
    sleep 2
    send -- "Y\r"
    sleep 3
    send -- "N \r"
    sleep 4
    expect "Please select public key type for user authentication*"
    send -- "R \r"
    sleep 2
    expect  "*password"
    sleep 2
    expect "sftp-client>"
    sleep 2
    send -- "put log.log $hosts.log \r "
    sleep 2
    expect "sftp-client>"
    sleep 2
    send -- "quit\r"
    sleep 2
    send -- "quit\r"
    sleep 2
    send -- "quit\r"
    }
    expect eof

你的问题是什么？要求是如果密码登录失败，即提示passwrd repeats我需要掌握以下命令并转到arrayTcl中的下一项。当你说“skill”时，你可能是指“skip”？是的，很抱歉输入错误，例如跳过错误的IP地址，您有一个您没有权限的设备，因此请转到下一个！
