way to do so is:

1) By using 'git add <file_spec>...'
- This can be performed multiple times before a commit. Note that this
- is not only for adding new files. Even modified files must be
- added to the set of changes about to be committed. The "git status"
- command gives you a summary of what is included so far for the
- next commit. When done you should use the 'git commit' command to
- make it real.

- content, so what you're really 'add'ing to the commit is the *content*
- of the file in the state it is in when you 'add' it.

2) By using 'git commit -a' directly
- This is a quick way to automatically 'add' the content from all files
- that were modified since the previous commit, and perform the actual
- commit without having to separately 'add' them beforehand. This will
- not add content from new files i.e. files that were never added before.
- Those files still have to be added explicitly before performing a
- commit.

But here's a twist. If you do 'git commit <file1> <file2> ...' then only
the changes belonging to those explicitly specified files will be

$ cd /home/alice/project

-$ git pull bob master

-First it adds the "remote" Bob's repository with the name "bob" and

+This merges the changes from Bob's "master" branch into Alice's
current branch. If Alice has made her own changes in the meantime,
then she may need to manually fix any conflicts. (Note that the
"master" argument in the above command is actually unnecessary, as it
The "pull" command thus performs two operations: it fetches changes
from a remote branch, then merges them into the current branch.
-You can perform the first operation alone using the "git fetch"
-command without merging them with her own branch, using:
+When you are working in a small closely knit group, it is not
+unusual to interact with the same repository over and over
+again. By defining 'remote' repository shorthand, you can make
+it easier:

+------------------------------------------------
+$ git remote add bob /home/bob/myrepo

+With this, you can perform the first operation alone using the
+"git fetch" command without merging them with her own branch,
+using:
-------------------------------------
$ git fetch bob
-------------------------------------
-which fetches the changes from Bob's branches. Then
+Unlike the longhand form, when Alice fetches from Bob using a
+remote repository shorthand set up with `git remote`, what was
+fetched is stored in a remote tracking branch, in this case
+`bob/master`. So after this:
-------------------------------------
$ git log -p master..bob/master
shows a list of all the changes that Bob made since he branched from
Alice's master branch.
-After examining those changes, and possibly fixing things, Alice
+After examining those changes, Alice
could merge the changes into her master branch:
-------------------------------------
-$ git checkout master
$ git merge bob/master
-------------------------------------
-The last command is a merge of the "bob/master" branch in Alice's
-own repository.
-
-Alice could also perform both steps at once with:
+This `merge` can also be done by 'pulling from her own remote
+tracking branch', like this:
-------------------------------------
-$ git pull bob
+$ git pull . remotes/bob/master
-------------------------------------
-This is just like the "git pull bob master" that we saw
-before, except that it also stores the unmerged changes from bob's
-master branch in bob/master before merging them into Alice's
-current branch. Note that git pull always merges into the current
-branch, regardless of what else is given on the commandline.
