git log - git log when HEAD is behind tip? -

let's head @ final commit in master, , log looks this

$ git log --oneline bcaee1c 15 july update 02ff17a add feature x 0910b6f end of weekly update c2b7189 add 03 july update 737be94 add feature y 

now want go @ past:

$ git checkout 0910b6f 

now log shows no hint of more recent state -- relative future head

$ git log --oneline  0910b6f end of weekly update c2b7189 add 03 july update 737be94 add feature y 

ok, no problem, "remember" or "write down" furthest-ahead commit bcaee1c , can git checkout bcaee1c, bammo, here comes phone call, bunch of emergency meetings, forced reboot, weekend, , "forget" , / or lose sticky note. come (much) later mental context blown , start creating away, discover later i've messed , have forensics job reset , revert , rewind.

can git log show future of head? there better git-fu scenario?

two things you:

1 @ tip of branch (master in case):

git checkout master 

2 git log show commits, , not starting head: use --all

git log --oneline --all 

note in case, git checkout master , git checkout bcaee1c might seem same, isn't exactly; must checkout branch; otherwise remain in detached head state.

edit 2 one-line command use lot have overview of whole tree:

git log --all --online --decorate --graph
