git branch -v、git branch -vv、git branch -verbose

git文檔

git branch
-v
-vv
--verbose
When in list mode, show sha1 and commit subject line for each head, along with relationship to upstream branch (if any). If given twice, print the name of the upstream branch, as well (see also git remote show <remote>).

翻譯說明

顯示每個（本地）分支當前指向的提交記錄的哈希值，以及和其上游分支的相對位置（如果有的話）
-v與-verbose是一個效果
-vv會顯示上游分支的名字

舉例

$ git branch -vv
  cyr_branch   689c970 [origin/cyr_branch: behind 2] default
* master       f1e2810 finally
  test-mysql   e2fa7b9 add .gitignore
  test-network 0d426ce add .gitignore
  xu_branch    e55fcf1 [origin/xu_branch: ahead 1] debug
  zfc_branch   e4a40a5 [origin/zfc_branch] merge

cyr_branch的上游分支為origin/cyr_branch，前者落后后者2
xu_branch的上游分支為origin/xu_branch，前者領先后者1
zfc_branch的上游分支為origin/zfc_branch，兩者同步
test-mysql和test-network沒有對應的上游分支
master的上游分支為origin/master，但是沒有顯示，我猜測是因為這個對應關系是固定的，所以無需顯示

組合用法

-a 顯示所有本地及遠端分支名

$ git branch -a
  cyr_branch
* master
  test-mysql
  test-network
  xu_branch
  zfc_branch
  remotes/origin/cyr_branch
  remotes/origin/master
  remotes/origin/xu_branch
  remotes/origin/zfc_branch

-av

$ git branch -av
  cyr_branch                689c970 [behind 2] default
* master                    f1e2810 finally
  test-mysql                e2fa7b9 add .gitignore
  test-network              0d426ce add .gitignore
  xu_branch                 e55fcf1 [ahead 1] debug
  zfc_branch                e4a40a5 merge
  remotes/origin/cyr_branch 1e63522 cyr
  remotes/origin/master     f1e2810 finally
