如何从 SFTP 服务器获取文件并将它们移动到 bash 脚本中的另一个文件夹？

Question

How do I get the one by one files from SFTP server and move them do another folder in Ubuntu bash script?

#!bin/sh
FOLDER=/home/SFTP/Folder1/    

sftp SFTP@ip_address    
cd /home/FSTP/Folder1/    
for file in "$FOLDER"*
<<EOF
cd /home/local/Folder1
get $file
EOF
mv $file /home/SFTP/Done
done

I know it's not right, but i've tried my best and if anyone can help me, i will appreciate it. Thanks in advance.

OpenSSH sftp is not very powerful client for such tasks. You would have to run it twice. First to collect list of files, use the list to generate list of commands, and execute those in a second run.

Something like this:

# Collect list of files
files=`sftp -b - user@example.com <<EOF
cd /source/folder
ls
EOF`
files=`echo $files|sed "s/.*sftp> ls//"` 

# Use the list to generate list of commands for the second run
(
  echo cd /source/folder
  for file in $files; do
    echo get $file
    echo rename $file /backup/folder/$file
  done
) | sftp -b - user@example.com

Before you run the script on production files, I suggest, you first output the generated command list to a file to check, if the results are as expected.

Just replace the last line with:

) > commands.txt

Maybe use SFTP internal command.

sftp get -r $remote_path $local_path 

OR with the -f option to flush files to disk

sftp get -rf $remote_path $local_path
