-c run a command

Separate all command with ;

mirror makes two directories identical. Default is remote to local

-R makes mirror local to remote

-P number specifies number of parallel connections

--ignore-time will only compare file size and existence

--continue will try again or resume if the connection fails.

--delete will remove files if no longer in the source.

lcd /local/directory; this is a separate command that specifies the local directory so that you can more easily script lftp otherwise it uses the current working directory.

pwd will print the working directory on the remote machine

lpwd will print the local working directory. That is where you ran the script from NOT what may be specified in the script.

lftp -c "set net:timeout 2 ; set net:max-retries 2 ; set net:reconnect-interval-base 5 ; open 192.168.1.41:2121/Music; lcd /local/directory; mirror -R -P 3 --ignore-time --delete --verbose"
