Branch copy-merge strategy for GIT to duplicate file that uses the same source in the repo

# I RAN BRANCHING twice with theses two dir with few operation at the end
export targetdir=gia-young-picasso-v05-2101082232
export srcdir1=gia-young-picasso-v05-add
export srcdir2=gia-young-picasso-v03-201216

## BRANCHING
for srcdir in $srcdir1 $srcdir2; do
  export branch_name=dup-$srcdir
  export tmp_new_dir=$srcdir'-new'
  git checkout -b $branch_name
  git mv $srcdir $tmp_new_dir
  git commit  -m "dub:$srcdir"
  git checkout  HEAD~ $srcdir

  git checkout -
  git merge --no-ff $branch_name

  # ---
  git mv $tmp_new_dir/*.jpg $targetdir
  git commit $targetdir -m "migrated:new-branch $srcdir"
  rmdir $tmp_new_dir
  git commit $tmp_new_dir -m cleanup
done
