我正在尝试编写我的第一个期望脚本，它将新语言推送到远程文件。

这是我到目前为止并没有真正起作用的东西：

#!/usr/bin/expect

set fid1 [open ./hosts.list r]
set hosts [read -nonewline $fid1]
close $fid1

set banner_cmd "cat > /tmp/new_sshd_banner << EOF


<New Language Goes Here>


EOF"
send "\n"

stty -echo
send_user "Enter password for remote sudo: "
expect_user -re "(.*)\n"
stty echo
set pass $expect_out(1,string)
send "\n"

foreach host [split $hosts "\n"] {
    eval spawn "/usr/bin/ssh $host"
    expect {
        -re "RSA key fingerprint" {send "yes\r"}
        timeout {puts "Host is known"}
    }

    expect "$host"
    send "sudo mv /etc/file /etc/file.orig"
    expect "assword"
    send $pass

    expect "$host"
    send "sudo $file_cmd"

    expect "$host"
    send "sudo mv /tmp/file /etc/file

}

当它运行时，这就是我所看到的：

opensuse @ 15:10 ~/bin> ./fix_file.exp 

Enter password for remote sudo: 
spawn /usr/bin/ssh server

<New Language Goes Here>

        timeout {puts "Host i..."
    (file "./fix_file.exp" line 45)

不太明显的一件事是，它将从用户那里获得的密码附加到 mv 命令的输出中。

我在哪里做错了？

正是错误所说的：

missing "
    while executing
"send "sudo mv /tmp/file /etc/file

您在该行之后缺少关闭 "：

    send "sudo mv /tmp/file /etc/file
