+git-quiltimport - Applies a quilt patchset onto the current branch
+
+
+SYNOPSIS
+--------
+[verse]
+'git-quiltimport' [--dry-run] [--author <author>] [--patches <dir>]
+
+
+DESCRIPTION
+-----------
+Applies a quilt patchset onto the current git branch, preserving
+the patch boundaries, patch order, and patch descriptions present
+in the quilt patchset.
+
+For each patch the code attempts to extract the author from the
+patch description. If that fails it falls back to the author
+specified with --author. If the --author flag was not given
+the patch description is displayed and the user is asked to
+interactively enter the author of the patch.
+
+If a subject is not found in the patch description the patch name is
+preserved as the 1 line subject in the git description.
+
+OPTIONS
+-------
+--dry-run::
+ Walk through the patches in the series and warn
+ if we cannot find all of the necessary information to commit
+ a patch. At the time of this writing only missing author
+ information is warned about.
+
+--author Author Name <Author Email>::
+ The author name and email address to use when no author
+ information can be found in the patch description.
+
+--patches <dir>::
+ The directory to find the quilt patches and the
+ quilt series file.
+
+ The default for the patch directory is patches
+ or the value of the $QUILT_PATCHES environment
+ variable.

+A tutorial introduction to git: part two
+========================================
+
+You should work through link:tutorial.html[A tutorial introduction to
+git] before reading this tutorial.
+
+The goal of this tutorial is to introduce two fundamental pieces of
+git's architecture--the object database and the index file--and to
+provide the reader with everything necessary to understand the rest
+of the git documentation.
+
+The git object database
+-----------------------
+
+Let's start a new project and create a small amount of history:
+
+------------------------------------------------
+$ mkdir test-project
+$ cd test-project
+$ git init-db
+defaulting to local storage area
+$ echo 'hello world' > file.txt
+$ git add .
+$ git commit -a -m "initial commit"
+Committing initial tree 92b8b694ffb1675e5975148e1121810081dbdffe
+$ echo 'hello world!' >file.txt
+$ git commit -a -m "add emphasis"
+------------------------------------------------
+
+What are the 40 digits of hex that git responded to the first commit
+with?
+
+We saw in part one of the tutorial that commits have names like this.
+It turns out that every object in the git history is stored under
+such a 40-digit hex name. That name is the SHA1 hash of the object's
+contents; among other things, this ensures that git will never store
+the same data twice (since identical data is given an identical SHA1
+name), and that the contents of a git object will never change (since
+that would change the object's name as well).
+
+We can ask git about this particular object with the cat-file
+command--just cut-and-paste from the reply to the initial commit, to
+save yourself typing all 40 hex digits:
+
+------------------------------------------------
+$ git cat-file -t 92b8b694ffb1675e5975148e1121810081dbdffe
+tree
+------------------------------------------------
+
+A tree can refer to one or more "blob" objects, each corresponding to
+a file. In addition, a tree can also refer to other tree objects,
+thus creating a directory heirarchy. You can examine the contents of
+any tree using ls-tree (remember that a long enough initial portion
+of the SHA1 will also work):
+
+------------------------------------------------
+$ git ls-tree 92b8b694
+100644 blob 3b18e512dba79e4c8300dd08aeb37f8e728b8dad file.txt
+------------------------------------------------
+
+Thus we see that this tree has one file in it. The SHA1 hash is a
+reference to that file's data:
+
+------------------------------------------------
+$ git cat-file -t 3b18e512
+blob
+------------------------------------------------
+
+A "blob" is just file data, which we can also examine with cat-file:
+
+------------------------------------------------
+$ git cat-file blob 3b18e512
+hello world
+------------------------------------------------
+
+Note that this is the old file data; so the object that git named in
+its response to the initial tree was a tree with a snapshot of the
+directory state that was recorded by the first commit.
+
+All of these objects are stored under their SHA1 names inside the git
+directory:
+
+------------------------------------------------
+$ find .git/objects/
+.git/objects/
+.git/objects/pack
+.git/objects/info
+.git/objects/3b
+.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad
+.git/objects/92
+.git/objects/92/b8b694ffb1675e5975148e1121810081dbdffe
+.git/objects/54
+.git/objects/54/196cc2703dc165cbd373a65a4dcf22d50ae7f7
+.git/objects/a0
+.git/objects/a0/423896973644771497bdc03eb99d5281615b51

+.git/objects/c4
+.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
+------------------------------------------------
+
+and the contents of these files is just the compressed data plus a
+header identifying their length and their type. The type is either a
+blob, a tree, a commit, or a tag. We've seen a blob and a tree now,
+so next we should look at a commit.
+
+The simplest commit to find is the HEAD commit, which we can find
+from .git/HEAD:
+
+------------------------------------------------
+$ cat .git/HEAD
+ref: refs/heads/master
+------------------------------------------------
+
+As you can see, this tells us which branch we're currently on, and it
+tells us this by naming a file under the .git directory, which itself
+contains a SHA1 name referring to a commit object, which we can
+examine with cat-file:
+
+------------------------------------------------
+$ cat .git/refs/heads/master
+c4d59f390b9cfd4318117afde11d601c1085f241
+$ git cat-file -t c4d59f39
+commit
+$ git cat-file commit c4d59f39
+tree d0492b368b66bdabf2ac1fd8c92b39d3db916e59

+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
+
+add emphasis
+------------------------------------------------
+
+The "tree" object here refers to the new state of the tree:
+
+------------------------------------------------
+$ git ls-tree d0492b36
+100644 blob a0423896973644771497bdc03eb99d5281615b51 file.txt
+$ git cat-file commit a0423896
+hello world!
+------------------------------------------------
+
+and the "parent" object refers to the previous commit:
+
+------------------------------------------------
+$ git-cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+
+initial commit
+------------------------------------------------
+
+The tree object is the tree we examined first, and this commit is
+unusual in that it lacks any parent.
+
+Most commits have only one parent, but it is also common for a commit
+to have multiple parents. In that case the commit represents a
+merge, with the parent references pointing to the heads of the merged
+branches.
+
+Besides blobs, trees, and commits, the only remaining type of object
+is a "tag", which we won't discuss here; refer to gitlink:git-tag[1]
+for details.
+
+So now we know how git uses the object database to represent a
+project's history:
+
+ * "commit" objects refer to "tree" objects representing the
+ snapshot of a directory tree at a particular point in the
+ history, and refer to "parent" commits to show how they're
+ connected into the project history.
+ * "tree" objects represent the state of a single directory,
+ associating directory names to "blob" objects containing file
+ data and "tree" objects containing subdirectory information.
+ * "blob" objects contain file data without any other structure.
+ * References to commit objects at the head of each branch are
+ stored in files under .git/refs/heads/.
+ * The name of the current branch is stored in .git/HEAD.
+
+Note, by the way, that lots of commands take a tree as an argument.
+But as we can see above, a tree can be referred to in many different
+ways--by the SHA1 name for that tree, by the name of a commit that
+refers to the tree, by the name of a branch whose head refers to that
+tree, etc.--and most such commands can accept any of these names.
+
+In command synopses, the word "tree-ish" is sometimes used to
+designate such an argument.
+
+The index file
+--------------
+
+The primary tool we've been using to create commits is "git commit
+-a", which creates a commit including every change you've made to
+your working tree. But what if you want to commit changes only to
+certain files? Or only certain changes to certain files?
+
+If we look at the way commits are created under the cover, we'll see
+that there are more flexible ways creating commits.
+
+Continuing with our test-project, let's modify file.txt again:
+
+------------------------------------------------
+$ echo "hello world, again" >>file.txt
+------------------------------------------------
+
+but this time instead of immediately making the commit, let's take an
+intermediate step, and ask for diffs along the way to keep track of
+what's happening:
+
+------------------------------------------------
+$ git diff
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+$ git update-index file.txt
+$ git diff
+------------------------------------------------
+
+The last diff is empty, but no new commits have been made, and the
+head still doesn't contain the new line:
+
+------------------------------------------------
+$ git-diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..513feba 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+So "git diff" is comparing against something other than the head.
+The thing that it's comparing against is actually the index file,
+which is stored in .git/index in a binary format, but whose contents
+we can examine with ls-files:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt
+$ git cat-file -t 513feba2
+blob
+$ git cat-file blob 513feba2
+hello world, again
+------------------------------------------------
+
+So what our "git update-index" did was store a new blob and then put
+a reference to it in the index file. If we modify the file again,
+we'll see that the new modifications are reflected in the "git-diff"
+output:
+
+------------------------------------------------
+$ echo 'again?' >>file.txt
+$ git diff
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+With the right arguments, git diff can also show us the difference
+between the working directory and the last commit, or between the
+index and the last commit:
+
+------------------------------------------------
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..ba3da7b 100644
+--- a/file.txt

+ hello world!

+------------------------------------------------
+
+At any time, we can create a new commit using "git commit" (without
+the -a option), and verify that the state committed only includes the
+changes stored in the index file, not the additional change that is
+still only in our working tree:
+
+------------------------------------------------
+$ git commit -m "repeat"
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+So by default "git commit" uses the index to create the commit, not
+the working tree; the -a option to commit tells it to first update
+the index with all changes in the working tree.
+
+Finally, it's worth looking at the effect of "git add" on the index
+file:
+
+------------------------------------------------
+$ echo "goodbye, world" >closing.txt
+$ git add closing.txt
+------------------------------------------------
+
+The effect of the "git add" was to add one entry to the index file:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0 closing.txt
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt
+------------------------------------------------
+
+And, as you can see with cat-file, this new entry refers to the
+current contents of the file:
+
+------------------------------------------------
+$ git cat-file blob a6b11f7a
+goodbye, word
+------------------------------------------------
+
+The "status" command is a useful way to get a quick summary of the
+situation:
+
+------------------------------------------------
+$ git status
+#
+# Updated but not checked in:
+# (will commit)
+#
+# new file: closing.txt
+#
+#
+# Changed but not updated:
+# (use git-update-index to mark for commit)
+#
+# modified: file.txt
+#
+------------------------------------------------
+
+Since the current state of closing.txt is cached in the index file,
+it is listed as "updated but not checked in". Since file.txt has
+changes in the working directory that aren't reflected in the index,
+it is marked "changed but not updated". At this point, running "git
+commit" would create a commit that added closing.txt (with its new
+contents), but that didn't modify file.txt.
+
+Also, note that a bare "git diff" shows the changes to file.txt, but
+not the addition of closing.txt, because the version of closing.txt
+in the index file is identical to the one in the working directory.
+
+In addition to being the staging area for new commits, the index file
+is also populated from the object database when checking out a
+branch, and is used to hold the trees involved in a merge operation.
+See the link:core-tutorial.txt[core tutorial] and the relevant man
+pages for details.
+
+What next?
+----------
+
+At this point you should know everything necessary to read the man
+pages for any of the git commands; one good place to start would be
+with the commands mentioned in link:everyday.html[Everyday git]. You
+should be able to find any unknown jargon in the
+link:glossary.html[Glosssay].
+
+The link:cvs-migration.html[CVS migration] document explains how to
+import a CVS repository into git, and shows how to use git in a
+CVS-like way.
+
+For some interesting examples of git use, see the
+link:howto-index.html[howtos].
+
+For git developers, the link:core-tutorial.html[Core tutorial] goes
+into detail on the lower-level git mechanisms involved in, for
+example, creating a new commit.

-Keeping track of history
-------------------------
+Exploring history
+-----------------
-Git history is represented as a series of interrelated commits. The
-most recent commit in the currently checked-out branch can always be
-referred to as HEAD, and the "parent" of any commit can always be
-referred to by appending a caret, "^", to the end of the name of the
-commit. So, for example,
+Git history is represented as a series of interrelated commits. We
+have already seen that the git log command can list those commits.
+Note that first line of each git log entry also gives a name for the
+commit:
-------------------------------------
-git diff HEAD^ HEAD
+$ git log
+commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+Author: Junio C Hamano <junkio@cox.net>
+Date: Tue May 16 17:18:22 2006 -0700
+
+ merge-base: Clarify the comments on post processing.
-------------------------------------
-shows the difference between the most-recently checked-in state of
-the tree and the previous state, and
+We can give this name to git show to see the details about this
+commit.
-------------------------------------
-git diff HEAD^^ HEAD^
+$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-------------------------------------
-shows the difference between that previous state and the state two
-commits ago. Also, HEAD~5 can be used as a shorthand for HEAD{caret}{caret}{caret}{caret}{caret},
-and more generally HEAD~n can refer to the nth previous commit.
-Commits representing merges have more than one parent, and you can
-specify which parent to follow in that case; see
-gitlink:git-rev-parse[1].
+But there other ways to refer to commits. You can use any initial
+part of the name that is long enough to uniquely identify the commit:
+
+-------------------------------------
+$ git show c82a22c39c # the first few characters of the name are
+ # usually enough
+$ git show HEAD # the tip of the current branch
+$ git show experimental # the tip of the "experimental" branch
+-------------------------------------
-The name of a branch can also be used to refer to the most recent
-commit on that branch; so you can also say things like
+Every commit has at least one "parent" commit, which points to the
+previous state of the project:
-------------------------------------
-git diff HEAD experimental
+$ git show HEAD^ # to see the parent of HEAD
+$ git show HEAD^^ # to see the grandparent of HEAD
+$ git show HEAD~4 # to see the great-great grandparent of HEAD
-------------------------------------
-to see the difference between the most-recently committed tree in
-the current branch and the most-recently committed tree in the
-experimental branch.
+Note that merge commits may have more than one parent:
-But you may find it more useful to see the list of commits made in
-the experimental branch but not in the current branch, and
+-------------------------------------
+$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
+$ git show HEAD^2 # show the second parent of HEAD
+-------------------------------------
+
+You can also give commits names of your own; after running
-------------------------------------
-git whatchanged HEAD..experimental
+$ git-tag v2.5 1b2e1d63ff
-------------------------------------
-will do that, just as
+you can refer to 1b2e1d63ff by the name "v2.5". If you intend to
+share this name with other people (for example, to identify a release
+version), you should create a "tag" object, and perhaps sign it; see
+gitlink:git-tag[1] for details.
+
+Any git command that needs to know a commit can take any of these
+names. For example:
-------------------------------------
-git whatchanged experimental..HEAD
+$ git diff v2.5 HEAD # compare the current HEAD to v2.5
+$ git branch stable v2.5 # start a new branch named "stable" based
+ # at v2.5
+$ git reset --hard HEAD^ # reset your current branch and working
+ # directory its state at HEAD^
-------------------------------------
-will show the list of commits made on the HEAD but not included in
-experimental.
+Be careful with that last command: in addition to losing any changes
+in the working directory, it will also remove all later commits from
+this branch. If this branch is the only branch containing those
+commits, they will be lost. (Also, don't use "git reset" on a
+publicly-visible branch that other developers pull from, as git will
+be confused by history that disappears in this way.)
-You can also give commits convenient names of your own: after running
+The git grep command can search for strings in any version of your
+project, so
-------------------------------------
-$ git-tag v2.5 HEAD^^
+$ git grep "hello" v2.5
-------------------------------------
-you can refer to HEAD^^ by the name "v2.5". If you intend to share
-this name with other people (for example, to identify a release
-version), you should create a "tag" object, and perhaps sign it; see
-gitlink:git-tag[1] for details.
+searches for all occurences of "hello" in v2.5.
-You can revisit the old state of a tree, and make further
-modifications if you wish, using git branch: the command
+If you leave out the commit name, git grep will search any of the
+files it manages in your current directory. So
-------------------------------------
-$ git branch stable-release v2.5
+$ git grep "hello"
-------------------------------------
-will create a new branch named "stable-release" starting from the
-commit which you tagged with the name v2.5.
+is a quick way to search just the files that are tracked by git.
-You can reset the state of any branch to an earlier commit at any
-time with
+Many git commands also take sets of commits, which can be specified
+in a number of ways. Here are some examples with git log:
-------------------------------------
-$ git reset --hard v2.5
+$ git log v2.5..v2.6 # commits between v2.5 and v2.6
+$ git log v2.5.. # commits since v2.5
+$ git log --since="2 weeks ago" # commits from the last 2 weeks
+$ git log v2.5.. Makefile # commits since v2.5 which modify
+ # Makefile
-------------------------------------
-This will remove all later commits from this branch and reset the
-working tree to the state it had when the given commit was made. If
-this branch is the only branch containing the later commits, those
-later changes will be lost. Don't use "git reset" on a
-publicly-visible branch that other developers pull from, as git will
-be confused by history that disappears in this way.
+You can also give git log a "range" of commits where the first is not
+necessarily an ancestor of the second; for example, if the tips of
+the branches "stable-release" and "master" diverged from a common
+commit some time ago, then
+
+-------------------------------------
+$ git log stable..experimental
+-------------------------------------
+
+will list commits made in the experimental branch but not in the
+stable branch, while
+
+-------------------------------------
+$ git log experimental..stable
+-------------------------------------
+
+will show the list of commits made on the stable branch but not
+the experimental branch.
+
+The "git log" command has a weakness: it must present commits in a
+list. When the history has lines of development that diverged and
+then merged back together, the order in which "git log" presents
+those commits is meaningless.
+
+Most projects with multiple contributors (such as the linux kernel,
+or git itself) have frequent merges, and gitk does a better job of
+visualizing their history. For example,
+
+-------------------------------------
+$ gitk --since="2 weeks ago" drivers/
+-------------------------------------
+
+allows you to browse any commits from the last 2 weeks of commits
+that modified files under the "drivers" directory.
+
+Finally, most commands that take filenames will optionally allow you
+to precede any filename by a commit, to specify a particular version
+fo the file:
+
+-------------------------------------
+$ git diff v2.5:Makefile HEAD:Makefile.in
+-------------------------------------
Next Steps
----------
-Some good commands to explore next:
+This tutorial should be enough to perform basic distributed revision
+control for your projects. However, to fully understand the depth
+and power of git you need to understand two simple ideas on which it
+is based:
- * gitlink:git-diff[1]: This flexible command does much more than
- we've seen in the few examples above.
+ * The object database is the rather elegant system used to
+ store the history of your project--files, directories, and
+ commits.
+
+ * The index file is a cache of the state of a directory tree,
+ used to create commits, check out working directories, and
+ hold the various trees involved in a merge.
+
+link:tutorial-2.html[Part two of this tutorial] explains the object
+database, the index file, and a few other odds and ends that you'll
+need to make the most of git.
+
+If you don't want to consider with that right away, a few other
+digressions that may be interesting at this point are:
* gitlink:git-format-patch[1], gitlink:git-am[1]: These convert
series of git commits into emailed patches, and vice versa,
