commit all the untracked files prior adding them to stage using "git add"

[Arup Rakshit <aruprakshit@rocketmail.com>]

Here is the currently added files in my repository :

arup@linux-wzza:~/Rails/test_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/
nothing added to commit but untracked files present (use "git add" to track)

Now I am looking for a way to add those in stage and commit also in a single 
line. So I did below :-

arup@linux-wzza:~/Rails/test_app> git commit -m "chapter 19 of Agile Web 
Development with Rails" -a
# 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/
nothing added to commit but untracked files present (use "git add" to track)

It did not work. Then using `git commit -h` told me, *-a* will work, for 
*tracked files*. Is there any way to add untracked files in stage, and commit in 
a single line ?
