rsync

This puts folder A into folder B:

rsync -avu --delete "/home/user/A" "/home/user/B"

If you want the contents of folders A and B to be the same, put /home/user/A/ (with the slash) as the source. This takes not the folder A but all of its content and puts it into folder B. Like this:

rsync -avu --delete "/home/user/A/" "/home/user/B"

- -a archive mode; equals -rlptgoD (no -H, -A, -X)
- -v run verbosely
- -u only copy files with a newer modification time (or size difference if the times are equal)
- --delete delete the files in target folder that do not exist in the source
- -z compress file data during the transfer
- -e specify the remote shell to use
- -P same as --partial --progress
- -c skip based on checksum, not mod-time & size

rsync push

rsync -avuz -e "ssh -p 22" /path/to/local/folder/ user@remotehost:/path/to/remote/folder/

zip individual files in a directory

for f in *.nes; do zip -r "${f%%.*}.zip" "$f"; done
