从远程服务器到本地服务器的Sftp文件

Question

Sorry if it's too much simple question. But I am Java developer, no idea of shell scripting. I googled, but couldn't find exactly what I am looking for.

My requirement

1. Connect to remote server using Sftp [authentication based on pub/pri keys]. A variable to point to private key file
2. Transfer files with specific extension [.log] to local server folder. Variable to set remote server path and local folder
3. Rename the transferred file in remote server
4. Log all the transferred files in a .txt file

Can any one give me shell script for this?

This is so far I framed from suggestions. Still some questions left on my side ;)

export PRIVKEY=${private_key_path}
export RMTHOST=user@remotehost
export RMTDIR=/logs/*.log
export LOCDIR=/downloaded/logs/
export LOG=sucess.txt

scp -i $PRIVKEY $RMTHOST:$RMTDIR $LOCDIR
for i in 'ls -1 $LOCDIR/*.log'
do
   echo $i >> $LOG
done

ssh $RMTHOST -c "for i in `ls -1 $RMTDIR; do mv /logs/$i /logs/$i.transferred; done"

What about this approach?

1. Connect to remote server using Sftp [authentication based on pub/pri keys]. A variable to point to private key file
2. Transfer files with specific extension [.log] to local server folder. Variable to set remote server path and local folder

scp your_user@server:/dir/of/file/*.log /your/local/dir

4. Log all the transferred files in a .txt file

for file in /your/local/dir/*.log
do
   echo "$file" >> $your_txt
done

3. Rename the transferred file in remote server

ssh your_user@server -c "for file in /dir/of/file/*.log; do mv /dir/of/file/"$file" /dir/of/file/new_name_based_on"$file"; done"

Use scp(secure copy) command to transfer file. You may also want to add the -C switch, which compresses the file. That can speed things up a bit. ie copy file1 from server1 to server2,

On server1:

#!/bin/sh
scp -C /home/user/file1 root@server2.com:/home/user

Edit:

#!/bin/sh
scp -i {path/to/pub/pri/key/file} /home/user/file1 root@server2.com:/home/user
