i delete line 1 "pick f694d12 test" , save it, got report

nothing 

how can fix it?

if save empty file during merge / rebase, git thinks changed mind , don't want anything. see second-to-last line in rebase todo file provided:

# however, if remove everything, rebase aborted. 

to work around this, can leave commit line, use drop command. todo file this:

drop f694d12 test  # rebase 3dad5af..f694d12 onto 3dad5af (1 command(s)) # # commands: # p, pick = use commit # r, reword = use commit, edit commit message # e, edit = use commit, stop amending # s, squash = use commit, meld previous commit # f, fixup = "squash", discard commit's log message # x, exec = run command (the rest of line) using shell # d, drop = remove commit # # these lines can re-ordered; executed top bottom. # # if remove line here commit lost. # # however, if remove everything, rebase aborted. # # note empty commits commented out 

alternatively, if want delete last commit, can this:

git reset --hard head^ 

or:

git reset --hard 3dad5af
