I'd work through a directory then as part of my 'completing' the work, would de-duplicate it using `jdupes` to ensure no files were duplicated. I'm sure you can see where this is going. 10 11 As part of my workflow, I was navigating directories, tapping the up arrow to repeat my last command and hitting enter with reckless abandon. I noted the command took a little longer than usual and immediately realised what I'd done. I went to assess the damage, when browsing using git, cgit, or even the github desktop client, all my repositories were broken except for a single bare repository. 12 13 The first thing to do is to find any potentially affected directories. This can simply be done via `find . -type d -name '.git'`. As what was deleted will only ever be duplicated content, you should be able to rebuild these repositories quite easily with the following: 14 15 ``` 16 cd affected-project 17 mv ".git" ".gitcontents" 18 git init 19 rsync --remove-source-files -av ".gitcontents" ".git" 20 find ".gitcontents" -empty -delete 21 ``` 22 23 Which should get you up and working again. 24 25 The moral of the story is to keep a backup, and then make a backup of your backup (just in case).
