Rsync calculate file count before transfer?

Question

When transferring lots of small files in many folders with rsync, it tends to stay around ir-chk=1000/xxxxx , where xxxxx keeps counting up as it discovers new files, and the amount to check stays around 1000 until its on its last few folders.

How can I have it check for the entire file count before copying?

The command I was using to copy was:

rsync -av --progress source dest

Answer 1

rsync -av --progress --dry-run --stats source dest

• Option --dry-run doesn't transfer any files but will show how many bytes will be transferred.
• Option --stats shows a summary.

a sample output:

...
tests/
tests/__init__.py
tests/test_config.py

Number of files: 5,033 (reg: 2,798, dir: 2,086, link: 149)
Number of created files: 5,032 (reg: 2,798, dir: 2,085, link: 149)
Number of deleted files: 0
Number of regular files transferred: 2,798
Total file size: 26,035,530 bytes
Total transferred file size: 26,032,322 bytes
Literal data: 0 bytes
Matched data: 0 bytes
File list size: 0
File list generation time: 0.004 seconds
File list transfer time: 0.000 seconds
Total bytes sent: 158,821
Total bytes received: 17,284

sent 158,821 bytes  received 17,284 bytes  117,403.33 bytes/sec
total size is 26,035,530  speedup is 147.84 (DRY RUN)

Get the number of files will be transferred

rsync -av --progress --dry-run --stats source dest | 
  fgrep 'Number of files' | 
  cut -d' ' -f4 | 
  tr -d ,
