--no-merged而不是--contains的git分支标志？

Question

git branch --contains master returns the names of branches from whose tips master is reachable.

git branch --merged master returns the names of branches whose tips are reachable from master .

git branch --no-merged master returns the names of branches whose tips aren't reachable from master .

What is the flag (perhaps in a newer version of git ?) to show the names of branches whose tips are neither reachable from master , nor can reach master in their own ancestry? In other words, what flag gives the effect of --no-merged --no-contains ?

To put it another way, how to show branches which could not have a fast forward merge into master nor have a fast forward merge from master into them?

Answer 1

Update April 2017 , as I mentioned in " How to list all git branches containing a commit ", the option --no-contains is now supported with Git 2.13 .

Original Answer

What is the flag (perhaps in a newer version of git?)

First, the --(no-)merged flags you mention have been generalized as ref-filter fairly recently (git 2.7, Sept. 2015) .

--no-contains

A quick search reveals this option does not exist (in any of the branches of the git repo:

MINGW64 ~/git/git (master)
$ git branch -a | tr -d \*|grep -v origin|xargs git grep --break --heading --line-number 'no\-contain'

So you would need to script that, listing all branches which are not selected by --contains (but are listed in --no-merged ).

" git tag/branch/for-each-ref " family of commands long allowed to filter the refs by:

• " --contains X " (show only the refs that are descendants of X ),
• " --merged X " (show only the refs that are ancestors of X ),
• " --no-merged X " (show only the refs that are not ancestors of X ).

One curious omission, " --no-contains X " (show only the refs that are not descendants of X ) has been added to them.
