After further development I need to add additional changes to previous commit.
I've made a lot of changes including from IDE, that handle file renames, creating new files, etc.
So git status shows a lot of files in staging area.
I do not want to add this files with git commit --amend --no-message.
Can I list these files as arguments to git commit --amend --no-message? Any other possibilities without disturbing index?
I think about stashing index - but it is complicated thing to list 40 files to ignore instead 2 files for amend....
After experimenting I found an easy (and obvious) solution:
$ echo x >> file1
$ echo x >> file2
$ echo y >> fileZZZ
(1)$ git add .
(2)$ git ci -m fix -- file1
(3)$ git commit --no-edit --amend -- file2
At (1) I add everything to the index. At (2) I commit only selected files leaving others (file2 and fileZZZ) in the index, at (3) I add missing file2 fix leaving fileZZZ in the index.
It is possible to work with Git almost ignoring the staging area.
