====== Copy with rsync ======

rsync can be used for both local and remote file transfer.

====== Local rsync ======

This example will copy the file testfile to the /tmp folder. If the transfer is interrupted transfer will be resumed if command is applied again.

  rsync -haP --append testfile /tmp/
  
  -h output numbers in a human-readable format
  -a archive mode; equals -rlptgoD
  -P = --progres --partial
  Where
  --progress show progress during transfer
  --partial keep partially transferred files
