Re: remote branch checkout issue, why its *(no branch)

"Sudipta GHOSH" [off-list ref] writes:

In our git repository there are few branches like

master
origin/B1
origin/B2

After doing  #git checkout origin/B1 I found that my current branch is
*(no branch)

#git branch
*(no branch)
master

Why its showing *(no branch) why not origin/B1

How I can checkout origin/B1 and after that my current branch will be
origin/B1 not the *(no branch)

First, 'origin/B1' is so called remote-tracking branch, and its full
name is refs/remotes/origin/B1.  Those branches are updated
_automatically_ by git on fetch, to follow branch 'B1' in 'origin'
repository.  Therefore, to not lose _your_ changes git doesn't allow
checking out remote-tracking branches.  You can checkout _state_ of
such branch into anonymous noname branch, so called in git jargon
"detached HEAD".


What you can do is to create _local_ branch, closely tied to
remote-tracking branch 'origin/B1', by using:

  $ git branch -b B1 --track origin/B1

Git would set up configuration for this branch in such way that "git
pull" command given on 'B1' branch would "do the right thing"(TM)


I really recommend reading "Git User's Manual" or "The Git Community
Book" first...
