File Synchronization (with remote machine)

Synchronize local directory with remote

rsync -a ~/dir1 username@remote_host:~/dir2

Synchronize remote directory with local

rsync -a username@remote_host:/home/username/dir1 ~/dir2

Use compression, show progress, and handle partial files

rsync -azP username@remote_host:/home/username/dir1 ~/dir2

More command options:

-a, --archive               archive mode; equals -rlptgoD (no -H,-A,-X)
    --delete                removes files in destination if not in source
-u, --update                skip files that are newer on the receiver
-h, --human-readable        output numbers in a human-readable format
-c, --checksum              skip based on checksum, not mod-time & size

File Integrity

md5sum * > files.md5  # generates a list of checksums for all files in directory
md5sum -c files.md5   # checks files in directory using list

Root commands
