rsync

Brief

  • Normal use: rsync -av <FROM> <TO>
  • Ignore modify date and size, just consider checksum: -c
  • Explain update motivation: -i
  • Dry run, don’t update anything: -n

Examples

rsync -avnic <SRC> <DST>|grep -e ^\> -e ^\<

Report file changing just by checksum (modified times and size could be equals, it ignores them)
