Create branch from another using commands (git)

  • 772

Within my project I am performing some tasks in a branch (branch_A), which was branched from the main branch of the project (master). Now I need to create a new branch, born from branch_A (say branch_A_branch)

How can I create a new branch from another already created with commands?

When I work from master, I do the build with:

git checkout -b "rama_A"

Would it be correct to place myself in branch_A (in this case I am already with -b) and from there do the same step?

It would be:

git checkout rama_A
git checkout -b "rama_A_ramificación"

And one last thing, to later merge these two branches (branch_A and branch_A_branch), that is, save the changes from branch A to branch_A itself, how should I do it? I am right?

git

    Your deduction is correct. The usual procedure with Git is to have two main branches (Master and Development) and usually one branch per developer (for development teams), and each developer would branch their personal branch based on various criteria (functionality, task, milestone...). In simple developments, Development is used as the main development branch and branches according to the criteria mentioned above. In your case your branch_A would be Development or the development branch so it would be correct to use git checkout -b rama_A_ramificación. If you use Git bash make sure git branchyou are on the branch you want the new branch to inherit from.

    With this structure you could build functionality into your branch_A and branch_A_Branch and you can merge changes by persisting your branch (add -A, commit -m "", push) and pulling from the branch you want to merge into: From branch_A_branch

    git add -A
git commit -m "New functionality"
git push origin rama_A_ramificacion
git checkout rama_A
git pull origin rama_A_ramificacion

    or use the command git merge rama_A_ramificaciónfrom your branch_A .

  2. The command git branch ＜new-branch＞allows you to create a new branch branch.

    Once created, you can use git checkout new_branchto switch to that branch.

    The command git checkoutaccepts the argument -b, which will create the new branch and switch to it instantly.

    The following command creates the branch <new-branch>based on <existing-branch>and switches to ＜new-branch＞instantly

    git checkout -b ＜new-branch＞ ＜existing-branch＞
