指定密码在Bash脚本为sftp [英] Specify password to sftp in a Bash script

问题描述

我想编写一个脚本来备份文件过SFTP。问题是，它需要一个密码，我看不出有什么办法来手动指定密码SFTP。我听说过，需要使用公共密钥没有密码，但需要能够ssh到远程服务器，并修改一些配置文件，这一点我是做不到的。

I am trying to write a script to back up a file over SFTP. The problem is, it requires a password, and I see no way to manually specify a password to SFTP. I've heard about requiring no password by using public keys, but that requires being able to ssh into the remote server and modify some configuration files, which I cannot do.

目前我的解决方法是使用卷曲，但是这是不安全的（正常使用FTP）。我又看了看的.netrc 文件，但是这似乎是FTP，而不是SFTP。如何手动为SFTP指定密码吗？

Currently my solution is to use cURL, but that is insecure (uses normal FTP). I also looked at the .netrc file, but that seems to be for FTP instead of SFTP. How do I manually specify a password for sftp?

推荐答案

LFTP允许指定的FTP和SFTP密码，也不需要公钥的。您的SH同步脚本可能是这样的：

Lftp allows specifying passwords for both ftp and sftp and does not require public keys at all. Your sh sync script may look like this:

#!/bin/sh
# Define folders
THEFOLDER='/mnt/my/folder'
# List files
THEFILES=`ls -p $THEFOLDER | grep -v "/"`

for file in $THEFILES
do
  echo "Processing $file"
  lftp -u login,password -e "put $THEFOLDER/$file;quit"  theftp/sub/folder
done
