Question

I accidentally added many files (test files) which I do not want them to be part of commit.

I want to reset the branch back to the head, but I already have few files which I have modified, and which I want them to be part of next commit.

Files that I want to commit and files that I do not want to commit are located in separate folder.

Is there anyway that I can discard newly added files, and keep the modified files with git command?

Below is the status that I got.

# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   new file:   Makefile
#   //and 100 of other files in current directory
#
# 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:   ../program.C
#   modified:   ../program.h
#   //and few more files..

git reset <directory> will recursively unstage any files in that directory. Alternately, just git reset to unstage everything, and git add <files> to add back just what you want.
