updating the underlying branch-CodePudding

in my version control I have:

branchA was checked out from master and branchB was checked out from branchA:

master -> branchA -> branchB

Questions:

if I update and push to branchA then how do I pull the update into branchB?
is there a way to verify what is the origin of a particular branch (I mean where it was checkout out from, sorry if the terminology is incorrect)

CodePudding user response：

Merge branchA into branchB would bring you the changes from branchA to branchB:

git checkout branchB
git merge branchA

With git log you can see your commit history in the terminal and also the origin/emergence of all branches. Have also a look in this question.

Another approach is a Git GUI-Client that visualizes a nice Git history tree by default, giving you a simple overview.

To find a suitable Git GUI-Client, see this documentation.
