shell - 将文件读入 String 并在 Expect Script 中执行循环

Question

我想要做的是:

创建一个 .exp文件，将从 *.txt 中读取文件，并将文本文件中的所有内容解析为expect脚本中的字符串变量。

循环包含一系列主机名的字符串，并执行一系列命令，直到字符串被枚举。

所以脚本的作用是从 txt 中读取一系列主机名。同目录下的文件，然后将它们读入字符串，.exp文件将自动登录到每个文件并执行一系列命令。

我编写了以下代码，但它不起作用:

#!/usr/bin/expect

set timeout 20
set user test
set password test

set fp [open ./*.txt r]
set scp [read -nonewline $fp]
close $fp

spawn ssh $user@$host

expect "password"
send "$password\r"

expect "host1"
send "$scp\r"

expect "host1"
send "exit\r"

任何帮助是极大的赞赏....

代码应该将两个文件的内容读入行列表，然后遍历它们。它最终是这样的:

# Set up various other variables here ($user, $password)

# Get the list of hosts, one per line #####
set f [open "host.txt"]
set hosts [split [read $f] "\n"]
close $f

# Get the commands to run, one per line
set f [open "commands.txt"]
set commands [split [read $f] "\n"]
close $f

# Iterate over the hosts
foreach host $hosts {
    spawn ssh $user@host
    expect "password:"
    send "$password\r"

    # Iterate over the commands
    foreach cmd $commands {
        expect "% "
        send "$cmd\r"
    }

    # Tidy up
    expect "% "
    send "exit\r"
    expect eof
    close
}

您可以使用一两个工作程序对其进行重构，但这是基本思想。
