Synchronizing files with rsync

rsync

# Synchronize directories with rsync and ssh:
# -r  recursive
# -c  skip based on checksum, not mod-time & size
# -h  output numbers in a human-readable format
# -a  archive mode
# -v  verbose mode
# -e  define shell used as transport 
# -P  same as --partial --progress: keeps partial transfered files if interrupted AND shows progress
# --delete to delete extraneous files on dest dir
rsync -rav -e "ssh -l $_USERNAME" --delete $_SOURCE_DIR $_DEST_DIR

# IMPORTANT: DIR must end with a trailing slash, e.g. /Users/pedro/Projects/

# "Hard" (delete extraneous files) synchronize a local directory on a remote directory (like git push)
_USER=<NAME> _SERVER=<NAME> _FROM=<NAME> _TO=<NAME>; rsync -rchavP -e "ssh -l $_USER" --delete "$_FROM" "$_SERVER":"$_TO"
