# Usage:
|
|
# ./upload_git.sh -r <remote-url> [-b branch] [-m "commit message"]
|
|
# ./upload_git.sh --remote <remote-url> --branch main --message "Update README"
|
|
#
|
|

|
|
# - If origin already exists, -r/--remote can be omitted.
|
|
# - If the working tree has changes, provide -m/--message to commit them.
