============
-p|--paginate::
Pipe all output into 'less' (or if set, $PAGER).
+--no-pager::
+ Do not pipe git output into a pager.
+
--git-dir=<path>::
Set the path to the repository. This can also be controlled by
setting the GIT_DIR environment variable.
+--work-tree=<path>::
+ Set the path to the working tree. The value will not be
+ used in combination with repositories found automatically in
+ a .git directory (i.e. $GIT_DIR is not set).
+ This can also be controlled by setting the GIT_WORK_TREE
+ environment variable and the core.worktree configuration
+ variable.
+
--bare::
- Same as --git-dir=`pwd`.
+ Treat the repository as a bare repository. If GIT_DIR
+ environment is not set, it is set to the current working
+ directory.

FURTHER DOCUMENTATION
---------------------
See the references above to get started using git. The following is
probably more detail than necessary for a first-time user.
-The <<Discussion,Discussion>> section below and the
-link:core-tutorial.html[Core tutorial] both provide introductions to the
-underlying git architecture.
+The link:user-manual.html#git-concepts[git concepts chapter of the

+introductions to the underlying git architecture.
See also the link:howto-index.html[howto] documents for some useful
examples.
specifies a path to use instead of the default `.git`
for the base of the repository.
+'GIT_WORK_TREE'::
+ Set the path to the working tree. The value will not be
+ used in combination with repositories found automatically in
+ a .git directory (i.e. $GIT_DIR is not set).
+ This can also be controlled by the '--work-tree' command line
+ option and the core.worktree configuration variable.

git Commits
~~~~~~~~~~~
'GIT_AUTHOR_NAME'::

~~~~~
+'GIT_MERGE_VERBOSITY'::
+ A number controlling the amount of output shown by
+ the recursive merge strategy. Overrides merge.verbosity.
+ See gitlink:git-merge[1]
+
'GIT_PAGER'::
- This environment variable overrides `$PAGER`.
+ This environment variable overrides `$PAGER`. If it is set
+ to an empty string or to the value "cat", git will not launch
+ a pager.
+
+'GIT_SSH'::
+ If this environment variable is set then gitlink:git-fetch[1]
+ and gitlink:git-push[1] will use this command instead
+ of `ssh` when they need to connect to a remote system.
+ The 'GIT_SSH' command will be given exactly two arguments:
+ the 'username@host' (or just 'host') from the URL and the
+ shell command to execute on that remote system.
++
+To pass options to the program that you want to list in GIT_SSH
+you will need to wrap the program and options into a shell script,
+then set GIT_SSH to refer to the shell script.
++
+Usually it is easier to configure any desired options through your
+personal `.ssh/config` file. Please consult your ssh documentation
+for further details.
+
+'GIT_FLUSH'::
+ If this environment variable is set to "1", then commands such
+ as git-blame (in incremental mode), git-rev-list, git-log,
+ git-whatchanged, etc., will force a flush of the output stream
+ after each commit-oriented record have been flushed. If this
+ variable is set to "0", the output of these commands will be done
+ using completely buffered I/O. If this environment variable is
+ not set, git will choose buffered or record-oriented flushing
+ based on whether stdout appears to be redirected to a file or not.
'GIT_TRACE'::
If this variable is set to "1", "2" or "true" (comparison

+
+More detail on the following is available from the
+link:user-manual.html#git-concepts[git concepts chapter of the
+user-manual] and the link:core-tutorial.html[Core tutorial].
+
+A git project normally consists of a working directory with a ".git"
+subdirectory at the top level. The .git directory contains, among other
+things, a compressed object database representing the complete history
+of the project, an "index" file which links that history to the current
+contents of the working tree, and named pointers into that history such
+as tags and branch heads.
+
+The object database contains objects of three main types: blobs, which
+hold file data; trees, which point to blobs and other trees to build up
+directory heirarchies; and commits, which each reference a single tree
+and some number of parent commits.
+
+The commit, equivalent to what other systems call a "changeset" or
+"version", represents a step in the project's history, and each parent
+represents an immediately preceding step. Commits with more than one
+parent represent merges of independent lines of development.
+
+All objects are named by the SHA1 hash of their contents, normally
+written as a string of 40 hex digits. Such names are globally unique.
+The entire history leading up to a commit can be vouched for by signing
+just that commit. A fourth object type, the tag, is provided for this
+purpose.
+
+When first created, objects are stored in individual files, but for
+efficiency may later be compressed together into "pack files".
+
+Named pointers called refs mark interesting points in history. A ref
+may contain the SHA1 name of an object or the name of another ref. Refs
+with names beginning `ref/head/` contain the SHA1 name of the most
+recent commit (or "head") of a branch under developement. SHA1 names of
+tags of interest are stored under `ref/tags/`. A special ref named
+`HEAD` contains the name of the currently checked-out branch.
+
+The index file is initialized with a list of all paths and, for each
+path, a blob object and a set of attributes. The blob object represents
+the contents of the file as of the head of the current branch. The
+attributes (last modified time, size, etc.) are taken from the
+corresponding file in the working tree. Subsequent changes to the
+working tree can be found by comparing these attributes. The index may
+be updated with new content, and new commits may be created from the
+content stored in the index.
+
+The index is also capable of storing multiple entries (called "stages")
+for a given pathname. These stages are used to hold the various
+unmerged version of a file when a merge is in progress.
