Shell script to move files on remote SFTP Server - linux

Question

I am trying to move files from one directory to another directory on the remote SFTP Server through shell script after downloading files locally. I understand that there is no wildcard move files function, so it seems that my only option is to rename files individually.
Can someone help me with the code below if there is a better way of writing this code.
All i am trying to do is move files to archive directory on the SFTP Server, once files are downloaded to my local directory.
I know there are other ways to do it with python/perl scripts but i am restricted to use Shell scripting on linux box.
#!/usr/bin/ksh
#LOGGING
LOGFILE="/tmp/test.log"
#SFTP INFO
FTP_SERVER="test.rebex.net"
FTP_USER="demo"
FTP_PWD="password"
FTP_PORT=22
FTP_PICKUP_DIR="/"
LOCAL_DIR="/"
#-------DOWNLOAD FILES
expect <<END #> $LOGFILE
send "$(date)\r";
spawn sftp $FTP_USER#$FTP_SERVER
expect "*password: "
send "$FTP_PWD\r";
expect "sftp> "
send "mget *.ext\r"
expect "sftp>"
send "exit\r"
END
#--------- MOVE FILES TO ARCHIVE ON SERVER
cd /home/ravi/Files
for fl in *.ext
do
expect <<END #> $LOGFILE
send "$(date)\r";
spawn sftp $FTP_USER#$FTP_SERVER
expect "*password: "
send "$FTP_PWD\r";
expect "sftp> "
send "rename $fl /ARCHIVE/$fl\r"
expect "sftp>"
send "exit\r"
END
done
#For Loop End

Answer 1

you can use lftp with mmv option
mmv [-O directory] file(s) directory
Move specified files to a target directory. The target directory can be specified after -O
option or as the last argument.
-O <dir> specifies the target directory where files should be placed
Reference
Example usage
lftp -u $FTP_USER,$FTP_PWD sftp://$FTP_SERVER:22 <<EOF
mmv dir/to/path /dir/to/renamed/path
EOF
