Git this script lists the files that are larger than the size you specify. Example use: python git-find-big-files.py fix-remove-files 1000000 (file size in MBs)
#!/usr/bin/python
# run the script: python git-find-big-files.py <the branch> <file size>
# Example use: python git-find-big-files.py fix-remove-files 1000000 (this value equals 1 Megabyte)
# the Fix-remove-files specifies the branch that you are cleaning

A poem by Bram Cohen, creator of BitTorrent: The Revolution Will Not Be Monetized
You are in the wrong place
You aren't going to find what you came for
You might as well go home
You aren't going to get rich here
Because the revolution will not be monetized
The revolution will not have a multi-billion dollar addressable market
The revolution will not follow a freemium business model
The revolution will not come free to play
The revolution will not enroll in YCombinator

Rsync over SSH - (40MB/s over 1GB NICs)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
  • H: preserves hard-links
  • A: preserves ACLs
