Can we stage all files using "git add" command, except some specific files ?

Hi,

Look below :

arup@linux-wzza:~/Rails/app> git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       .gitignore
#       Gemfile
#       Gemfile.lock
#       README.rdoc
#       Rakefile
#       app/
#       bin/
#       config.ru
#       config/
#       db/
#       lib/
#       log/
#       public/
#       test/
#       vendor/
arup@linux-wzza:~/Rails/app> git add -A
arup@linux-wzza:~/Rails/app> git status
# On branch master
#
# Initial commit
#
# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#       new file:   .gitignore

arup@linux-wzza:~/Rails/app> git rm --cached .gitignore
rm '.gitignore'
arup@linux-wzza:~/Rails/app> git rm --cached bin/bundle
rm 'bin/bundle'


Now, you can see, I have staged all the files first using *git add -A*, then 
_unstaging_ those I don't want to _stage_ right now. Now can this be done, in 
the *staging* time ? I mean any way to tell `git add` command, that add all 
the files from the current directory, except some specific files. What I want 
this is, some times I have at least 30 files, whereas I want to _stage_ say, 20 
files, not the rest 10. During _staging_ can I tell *git add* the same. I used 
*git add -h*, which didn't show me any such hints about my need.
