replaced objects and working directory

$ git init $ echo 1 > 1 $ git add 1 $ SHA1=`git hash-object 1` $ git ci -m 1 $ echo 2 >> 1 $ git add 1 $ git ci -m 2 $ SHA2=`git hash-object 1` $ git replace $SHA1 $SHA2 $ git st # On branch master nothing to commit (working directory clean) $ git co HEAD^ $ git st # Not currently on any branch. # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: 1 # no changes added to commit (use "git add" and/or "git commit -a") $ git di
