expect script inside bash script
提问by John
I am really stumped! I DONT WANT TO USE RSA AUTH SO PLEASE ABSTAIN.
我真的很难过！我不想使用 RSA 授权，所以请弃权。
#!/bin/bash
echo "Enter the server password"
read password
cd /home/mike/
# this is included the code below ->
/usr/bin/expect << EOD
set timeout -1
spawn scp file.txt server.com:/home
expect {
timeout { send_user "TIME OUT\n"; exit 1 }
"*assword: "
}
send "$password\r"
expect {
"s password: " { send_user "\nIncorrect Password. Login Failed.\n"; exit 1 }
"100%"
}
sleep 1
send "exit\r"
expect eof
This works and file.txt gets transferred to the server but I get this warning message ->
这有效并且 file.txt 被传输到服务器，但我收到此警告消息 - >
" line 44: warning: here-document at line 22 delimited by end-of-file (wanted `EOD')"
When I add EOD at the end after 'expect eof' it gives me this error ->
当我在“expect eof”之后添加 EOD 时，它给了我这个错误 ->
send: spawn id exp4 not open
while executing
"send "exit\r"
Any help would be appreciated. I am saying again I cant use pubkey auth so please dont suggest that.
任何帮助，将不胜感激。我再说一遍我不能使用公钥身份验证所以请不要建议。

By replacing your last line:
通过替换你的最后一行：
expect eof
with:
和：
EOD
I don't get the complaint anymore. Note that you cannot have any tabs (and maybe spaces as well?) before your EODtag (which you defined in your initial /usr/bin/expectline.
我不再收到投诉了。请注意，在EOD标签（您在初始/usr/bin/expect行中定义的）之前不能有任何制表符（也可能有空格？）。

Instead of trying to script this using expect, you can simply use curlto copy files to/from a remote host via scp or sftp, and pass the authentication credentials to the curl command like so:
expect您可以简单地使用curl通过 scp 或 sftp 将文件复制到远程主机或从远程主机复制文件，而不是尝试编写脚本，并将身份验证凭据传递给 curl 命令，如下所示：
curl sftp://remotehost.domain.com/path/to/remote/file --user username:password -o /path/to/local/file
