Question & Answer :
Fto’s opportunity that I person a graph similar this:
A---B---C---D (maestro) \ \-E---F (Caput)
If I bash git log --each --oneline, I volition acquire each six of my commits.
However if the graph is:
A---B---C---D (maestro, Caput) \ \-E---F
I volition not seat E and F. Tin I acquire Git to archer maine each the commits, together with these connected branches which are not named?
Attempt:
git log --reflog
which lists each git commits by pretending that each objects talked about by reflogs (git reflog) are listed connected the bid formation arsenic <perpetrate>.
