show refs points to a commit

show refs points to a commit

[Ralf Thielow]

After playing around with submodules, I haven't
found a builtin way to show refs pointing to a
specified commit without using UNIX pipes.

Especially when you working with submodules, it
would be very helpful to know which refs
points to this commit in order to switch from
"detached HEAD" to the branch you can (maybe)
work with.

Or did I miss something?

Thanks

Ralf

Is this what you mean ?

$ git rev-parse master
f623ca1cae600e97cb0b38131fdd33e4fb669cf8
$ git name-rev f623ca1cae600
f623ca1cae600 master
$ git name-rev --refs=refs/heads/* f344333cd
f344333cd master~10

I just want to know what's the refs where
the *tip* points to my specified commit.

"git for-each-ref" gives the mapping from the tip of your refs to
object names.  We do not keep and give reverse mapping but there
should be enough information in for-each-refs output to get the
information yourself, I think.

But you need to grep if you have a big list, don't you?
Michael H. points me to: "git log -1 --decorate"
which works very well to me.
