Delete all unused repositories and forgotten forks in 6 (semi)-automatic steps!
Ugh. Github forces me to type my password for every fork and repository I want to delete. That’s smart and all, but what if one wants to mass-delete a bunch of old, unused, forgotten, dirty little repositories that make his repository list look like a mess? well, that person follows this short guide:
[1.] Open in a new tab all to-be-deleted github repositores (Use the mouse’s middle click)
https://github.com/wildeyes?tab=repositories
[2.] Use one tab https://chrome.google.com/webstore/detail/onetab/chphlpgkkbolifaimnlloiipkdnihall?hl=en to shorten them to a list.
[3.] Save that list to to a file somewhere. The list should be in the form of “ur_username/repo_name” per line, not a full URL!
[4.] Register a new personal access token with a delete_repo permission at this address
https://github.com/settings/tokens/new
[5.] Use the line appropriate for your operating system below, replacing UR_TOKEN with your access_token.
[6.] For OSX + Linux:
while read repo; do curl -X DELETE -H "Authorization: token UR_TOKEN" "https://api.github.com/repos/$repo"; done < repos.txt
[7.] For Windows: Run in powershell:
get-content D:\repolist.txt | ForEach-Object { Invoke-WebRequest -Uri https://api.github.com/repos/$_ -Method "DELETE" -Headers @{"Authorization"="token UR_TOKEN"} }
