For our day to day work it is good we can delete the branch form local and remote repositories by using cli.
For this purpose git has very simple commands to use and those are:
git branch -D branch_name
git push origin :branch_name
e.g
say my branch name is git_delete_branch then my steps are.
1) git branch -D git_delete_branch
2) git push origin :git_delete_branchFor a working illustration of above commands please refer :
