I would like to automate a bash script, that connects to server using sftp and does a file transfer. I have the password for this, and initially I tried for this
我想自动化一个 bash 脚本，它使用 sftp 连接到服务器并进行文件传输。我有这个密码，最初我试过这个
sftp $acc@$host << EOF
<passwd_here>
cd $dir
get $file
quit
EOF
but it still prompted for password, and I had to enter it manually at the prompt.
但它仍然提示输入密码，我不得不在提示下手动输入。

With scp/sftp you should use key-based authentication. Public key from the user you want to authenticate copy into ~/.ssh/authorized_keys file on the server, into home directory of user on which you want log on. Storing password in clear text on client side is not a good practice, you know :) That way you "workaround" problem of reading password from the prompt too.
对于 scp/sftp，您应该使用基于密钥的身份验证。来自您要验证的用户的公钥复制到服务器上的 ~/.ssh/authorized_keys 文件中，到您要登录的用户的主目录中。在客户端以明文形式存储密码不是一个好习惯，你知道:) 这样你也可以“解决”从提示中读取密码的问题。
