group_by_owner.sh

#!/bin/bash
#
# group_by_owner script reads directory (passed as a first agrument),
# finds any Git-repositories in subdirectories,
# parses first the line from `git remote -v` for each repositry,
# moves repository to ~/Projects/<owner>/<repo>
#
# ⚠️ Can work incorrectly for repositories with many "remotes"
#    (or without any "remotes").
#
# Usage:
# sh group_by_owner.sh ~/IdeaProjects
# sh group_by_owner.sh ~/GolandProjects
# sh group_by_owner.sh ~/PycharmProjects
