So unless you know and use [git annex](https://git-annex.branchable.com/), this is not going to be very useful for you. Check it out, though. It's pretty cool. Unless you are on Windows. In that case it's hell. Anyway, I wrote a script to help me figure out the output of [git annex unused](http://manpages.ubuntu.com/manpages/wily/man1/git-annex-unused.1.html). In short, it tells you what those files used to be called before you lost them. Script:
You can either call it with one argument which should be a key, or if you call it with no argument, it expects you to paste the list of results you got from
#!/usr/local/bin/python3.5 import re, sys, os from subprocess import Popen,PIPE FNULL = open(os.devnull, 'w') def seeker(s): process = Popen(["git", "log", "--stat", "-S", s], stderr=FNULL, stdout=PIPE) log = process.stdout.read().decode("utf-8") match = re.search(r"(([ -~]*\/)*[ -~]*)\|", log) if not match: return '' else: return match.group(1).strip() if len(sys.argv)>1: print( seeker(sys.argv) ) else: clist =  while True: crawl = input().strip() if not crawl: break crawl = crawl.split() clist.append(crawl) for x in clist: print('%s : %s' % ( x, seeker(x) ) )
git annex unusedinto stdin. It then goes through the list and tells you the corresponding filename for each key. This script is phenomenally stupid in that it does quite a terrible regular expression search on the output of git log and returns the first match it finds. Sue me, it works pretty well at my end.
