user@$serverwhere it asks for password and I enter the password then I can run regular SFTP commands getand mgetto fetch files.
user@$server它要求输入密码，然后我输入密码，然后我可以运行常规 SFTP 命令get并mget获取文件。
The concern is that I have to provide password manually and it opens interactive shell. How can I run all these in just one command or without manual intervention.?
问题是我必须手动提供密码并打开交互式 shell。如何仅在一个命令中运行所有这些或无需人工干预。？

You can try the expectcommand:
你可以试试expect命令：
#!/usr/bin/expect -c "
spawn sftp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no <USER>@<SERVER>
expect \"*?assword:\"
send \"<PASSWORD>\r\"
expect \"sftp>\"
#more commands
#exit sftp when you're done
send \"exit\r\"
expect -exact \"$\"
"
It'll enter the password without manual intervention.
它会在没有人工干预的情况下输入密码。
UserKnownHostsFile=/dev/nullwill disable the host key checking and StrictHostKeyChecking=nowill disable strict host key checking.
UserKnownHostsFile=/dev/null将禁用主机密钥检查StrictHostKeyChecking=no并将禁用严格的主机密钥检查。
You can add that example in the #more commandssection:
您可以在该#more commands部分添加该示例：
#Example with get (from remote to local)
send \"get <remotefilepath> <localfilepath>\r\"
expect \"sftp>\"
