I want to know how to delete repo in github account. I cannot see any indicators to delete on github interface.
You can go to the main page of the repository and under your repository name, click "Settings"...
...and scroll down to the "Danger Zone"
Go to the settings page of your repo and the bottom you can find the "Delete this repository" button under the Danger Zone area. Enter your repository name to confirm the deletion and click "I understand the consequences, delete this repository" to confirm the operation. The url will endup like below if you visit the settings page of you repository,
https://github.com/GITHUB_USERNAME/REPOSITORY_NAME/settings
For example, if your name is john and have a repository named "sample_john" the url would look like this,
https://github.com/john/sample_john/settings
Warning: Doing the above operation will permanently delete your repository, wiki, issues, and comments, and remove all collaborator associations.
You might also want to delete repo from your .git/config file
git remote rm “alias or origin”
