我的主分支和开发分支在GitHub上被远程跟踪。如何克隆这两个分支?


当前回答

我编写了这些小PowerShell函数,以便能够签出我的所有Git分支,这些分支位于源远程。

Function git-GetAllRemoteBranches {
     iex "git branch -r"                       <# get all remote branches #> `
     | % { $_ -Match "origin\/(?'name'\S+)" }  <# select only names of the branches #> `
     | % { Out-Null; $matches['name'] }        <# write does names #>
}


Function git-CheckoutAllBranches {
    git-GetAllRemoteBranches `
        | % { iex "git checkout $_" }          <# execute ' git checkout <branch>' #>
}

更多的Git函数可以在我的Git设置库中找到。

其他回答

我试图找出如何删除我在本地删除的远程分支。起源不是我的,我不想经历重新克隆一切的麻烦。

这对我有用:

假设您需要在本地重新创建分支:

git checkout -b recreated-branch-name
git branch -a (to list remote branches)
git rebase remotes/remote-origin/recreated-branch-name

因此,如果我从gituser/master分支到sjp,然后将其分支到sjp/mynewbranch,则如下所示:

$ git checkout -b mynewbranch

$ git branch -a
  master
  remotes/sjp/master
  remotes/sjp/mynewbranch

$ git fetch (habit to always do before)

$ git rebase remotes/sjp/mynewbranch

首先,克隆一个远程Git存储库并将其cd到其中:

$ git clone git://example.com/myproject
$ cd myproject

接下来,查看存储库中的本地分支:

$ git branch
* master

但您的存储库中隐藏着其他分支!使用-a标志查看这些:

$ git branch -a
* master
  remotes/origin/HEAD
  remotes/origin/master
  remotes/origin/v1.0-stable
  remotes/origin/experimental

要快速查看上游分支,请直接查看:

$ git checkout origin/experimental

要处理该分支,请创建一个本地跟踪分支,该分支通过以下方式自动完成:

$ git checkout experimental

Branch experimental set up to track remote branch experimental from origin.
Switched to a new branch 'experimental'

这里,“新分支”只是指从索引中获取分支并在本地为您创建。正如前一行告诉的那样,正在设置分支以跟踪远程分支,这通常意味着origin/branch_name分支。

您的本地分支机构现在应该显示:

$ git branch
* experimental
  master

您可以使用gitremote跟踪多个远程存储库:

$ git remote add win32 git://example.com/users/joe/myproject-win32-port
$ git branch -a
* master
  remotes/origin/HEAD
  remotes/origin/master
  remotes/origin/v1.0-stable
  remotes/origin/experimental
  remotes/win32/master
  remotes/win32/new-widgets

在这一点上,事情变得非常疯狂,所以运行gitk看看发生了什么:

$ gitk --all &
#!/bin/bash
for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master `; do
   git branch --track ${branch#remotes/origin/} $branch
done

这些代码将把所有远程分支代码拉到本地存储库。

您可以轻松切换到分支,而无需使用花哨的“gitcheckout-b somebranch origin/somebranch”语法。您可以执行以下操作:

git checkout somebranch

Git将自动执行正确的操作:

$ git checkout somebranch
Branch somebranch set up to track remote branch somebranch from origin.
Switched to a new branch 'somebranch'

Git将检查在一个远程中是否存在同名的分支,如果存在,它将以与您明确指定的远程分支相同的方式对其进行跟踪。从git 1.8.2.1的git checkout手册页面:

如果未找到<branch>,但中确实存在跟踪分支只有一个具有匹配名称的远程(称为<remote>),视为相当于$git checkout-b<branch>--track<remote>/<branch>

在这里,我为您编写了一个很好的函数,使其易于重复

gitCloneAllBranches() { # clone all git branches at once easily and cd in
  # clone as "bare repo"
  git clone --mirror $1
  # rename without .git extension
  with_extension=$(basename $1)
  without_extension=$(echo $with_extension | sed 's/.git//')
  mv $with_extension $without_extension
  cd $without_extension
  # change from "bare repository" to not
  git config --bool core.bare false
  # check if still bare repository if so
  if [[ $(git rev-parse --is-bare-repository) == false ]]; then
    echo "ready to go"
  else
    echo "WARNING: STILL BARE GIT REPOSITORY"
  fi
  # EXAMPLES:
  # gitCloneAllBranches https://github.com/something/something.git
}
