Switch current branch in git bare repository

I actually want to remove a branch in the bare repository i am working with, but this task hits a dead end because I cannot switch away from the master repository without a 'work tree' which a bare repository does not have. When I run git branch -d master the output is: error: Cannot delete the branch 'master' which you are currently on. So I try to switch to another branch called 'develop' by run
