Git scripting: list of all git branches containing commit

Question

I can list all branches containing a specific commit using git branch --list --contains just fine. But, as explained in a related question about how to list all branches , this is a china command that should not be used in scripts.

The final question is to use the git for-each-ref plumbing command, but this does not support --contains .

What is the correct plumbing interface to list all branches containing a specific commit.

Answer 1

One possible solution using the git-for-each-ref and git merge-base plumbing commands (the latter was suggested by Joachim himself):

 #!/bin/sh # git-branchesthatcontain.sh # # List the local branches that contain a specific revision # # Usage: git branchthatcontain <rev> # # To make a Git alias called 'branchesthatcontain' out of this script, # put the latter on your search path, and run # # git config --global alias.branchesthatcontain \ # '!sh git-branchesthatcontain.sh' if [ $# -ne 1 ]; then printf "%s\n\n" "usage: git branchesthatcontain <rev>" exit 1 fi rev=$1 git for-each-ref --format='%(refname:short)' refs/heads | \ while read ref; do if git merge-base --is-ancestor "$rev" "$ref"; then printf "%s\n" "$ref" fi; done exit $? 

The script is available in Jubobs / git-aliases on GitHub.

(Edit: thanks coredump for showing me how to get rid of this nasty eval .)

Update after 18 months (April 2017) : with Git 2.13 (Q2 2017), git for-each-ref --no-contains <SHA1> is finally supported!

Original answer

Running Git 2.7 (Q4 2015) will give you a more complete version of git for-each-ref , which now support --contains

 git for-each-ref --contains <SHA1> 

With document

 --contains [<object>]: 

Only list tags that contain the specified commit (HEAD if not specified).

Some functions from " git tag -l " and " git branch -l " were made available for " git for-each-ref " so that the implementation could eventually be distributed among all three, in a subsequent series or two.
