Is that somehow possible? I am looking for a bash function that would take what git 1.8.3.1 offers and return only the tags accessible from the current branch tip. Could you, please, give me at least a hint how this could be done? Thank you clime ``` ## Jeff King, 2018-09-11 19:05 Subject: Re: with git 1.8.3.1 get only merged tags Message-ID: <20180911190519.GA8396@sigill.intra.peff.net> URL: https://gitlist.dev/e/20180911190519.GA8396%40sigill.intra.peff.net In-Reply-To: ``` On Tue, Sep 11, 2018 at 12:43:15PM +0200, Michal Novotny wrote: > I need to emulate git tag --merged with very old git 1.8.3.1.

This is not particularly fast, but it should work: git for-each-ref refs/tags | cut -f2 | while read tag; do test "$(git merge-base $tag HEAD)" = \ "$(git rev-parse $tag^{commit})" && echo $tag done -Peff ``` ## Michal Novotny, 2018-09-13 08:36 Subject: Re: with git 1.8.3.1 get only merged tags Message-ID: URL: https://gitlist.dev/e/CANT8FXSu9rqbw5D05LfcrD1GpenFGdB6TAcaHJGFJiouzctxJQ%40mail.gmail.com In-Reply-To: <20180911190519.GA8396@sigill.intra.peff.net> ``` On Tue, Sep 11, 2018 at 9:05 PM Jeff King wrote: > > On Tue, Sep 11, 2018 at 12:43:15PM +0200, Michal Novotny wrote: > > > I need to emulate git tag --merged with very old git 1.8.3.1.

Yes, that's exactly the case with RHEL-7. clime ```
