Last active December 21, 2015 13:19
retrync ("retrying rsync") executes resumable rsync uploading/downloading via SSH with progress over and over until the transfer is complete. First stick your public SSH key in ~/.ssh/authorized_keys on the remote server. Original version came from http://blog.iangreenleaf.com/2009/03/rsync-and-retrying-until-we-get-it.html
#!/bin/bash
# Usage: retrync path/to/thing/locally user@host:/path/where/you/want/it/remotely

Extract subdirectory in git, then slim down the history
$ git clone blahblahblah # <-- fresh clone of the repo
$ du -sh .
768M # <-- holy macaroni, that's huge
$ git filter-branch --subdirectory-filter path/to/subdir --prune-empty --tag-name-filter cat -- --all # <-- Actual filter
...
### Now we'll delete all references to those unchanged refs
$ git reflog expire --expire=now --all # <-- expire the reflog refs
