My 2¢ while using Git.

Pull

If you face the error below, when you do $git pull

There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details

	git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

	git branch --set-upstream develop origin/<branch>

Reset the upstream with below

$ git branch --set-upstream-to=origin/main main

from $man git-branch

	   -u <upstream>, --set-upstream-to=<upstream>
		   Set up <branchname>'s tracking information so <upstream> is
		   considered <branchname>'s upstream branch. If no <branchname> is
		   specified, then it defaults to the current branch.

Commits

Removing the Whole commit history (Remote)

Stack Overflow

This utilize a new branch which doesn’t have any history yet.

You don’t have to remove .git directory

Below, we assume you want to remove all the history under the main branch, but you can use any branch when ‘main’ appears.

$ git checkout --orphan tmp_branch
$ git add -A
$ git commit -am "Init"
$ git branch -D main			# delete the branch you want to purge history
$ git branch -m main			# rename new branch to the target branch name
$ git push -f origin main

Tags

Rename a tag (Remote)

Stack Overflow

git tag new old           # Create a new local tag named `new` from tag `old`.
git tag -d old            # Delete local tag `old`.
git push origin new :old  # Push `new` to your remote named "origin", and delete
						  #     tag `old` on origin (by pushing an empty tag
						  #     name to it).

Note that if you are renaming an annotated tag, you need to ensure that the new tag name is referencing the underlying commit and not the old annotated tag object that you’re about to delete.

If the old tag is an annotated tag, or you aren’t sure, you can use ^{} to dereference the object until a non-tag object is found:

# create a new annotated tag "new" referencing the object
# which the old annotated tag "old" was referencing:
$ git tag -a new old^{}

Archive a branch into tag

Archive

(See: Stack Overflow 1, Stack Overflow 2 )

Give a ‘archive’ tag name archive/new_name to the branch you want to archive.

$ git tag archive/new_name old_branch

Push

If you want to upload this archive to Github or Gitlab, you can do below.

(check your $ git remove -v for upstream name, normally it is origin)

$ git push origin archive/new_name

Remove the old branch (Local)

If you don’t want to preserve the old branch, you can delete one.

$ git branch -D old_branch

Remove the old branch (Remote)

$ git push -d origin old_branch

If you need to check it again, later

If you need to check the archived branch, later

You can create temporary tmp_branch and checkout to there, with archived archive/new_name(the name which you gave to the archive branch above) tag.

$ git checkout -b tmp_branch archive/new_name

Submodules

Re-pull the submodule after cloning the parent repository

Stack Overflow

If you fresh pulled the repo or chckout to some branch, you won’t have anything under submodule.

So, use below

$ git submodule update --init --recursive

Update the submodule

$ git submodule update --recursive --remote
