 809         option will bring up the manual page for that command.
 810 </p>
 811 <div class="paragraph"><p>Other options are available to control how the manual page is
 812 displayed. See <a href="git-help.html">git-help(1)</a> for more information,

 821         Run as if git was started in <em>&lt;path&gt;</em> instead of the current working
 822         directory.  When multiple <code>-C</code> options are given, each subsequent
 823         non-absolute <code>-C &lt;path&gt;</code> is interpreted relative to the preceding <code>-C
 824         &lt;path&gt;</code>.  If <em>&lt;path&gt;</em> is present but empty, e.g. <code>-C ""</code>, then the
 825         current working directory is left unchanged.
 826 </p>
 827 <div class="paragraph"><p>This option affects options that expect path name like <code>--git-dir</code> and
 828 <code>--work-tree</code> in that their interpretations of the path names would be
 829 made relative to the working directory caused by the <code>-C</code> option. For
 830 example the following invocations are equivalent:</p></div>
 831 <div class="literalblock">
 832 <div class="content">
 833 <pre><code>git --git-dir=a.git --work-tree=b -C c status

 841 <p>
 842         Pass a configuration parameter to the command. The value
 843         given will override values from configuration files.
 844         The &lt;name&gt; is expected in the same format as listed by
 845         <em>git config</em> (subkeys separated by dots).
 846 </p>
 847 <div class="paragraph"><p>Note that omitting the <code>=</code> in <code>git -c foo.bar ...</code> is allowed and sets
 848 <code>foo.bar</code> to the boolean true value (just like <code>[foo]bar</code> would in a
 849 config file). Including the equals but with an empty value (like <code>git -c
 850 foo.bar= ...</code>) sets <code>foo.bar</code> to the empty string which <code>git config
 851 --type=bool</code> will convert to <code>false</code>.</p></div>

 857 <p>
 858         Like <code>-c &lt;name&gt;=&lt;value&gt;</code>, give configuration variable
 859         <em>&lt;name&gt;</em> a value, where &lt;envvar&gt; is the name of an
 860         environment variable from which to retrieve the value. Unlike
 861         <code>-c</code> there is no shortcut for directly setting the value to an
 862         empty string, instead the environment variable itself must be
 863         set to the empty string.  It is an error if the <code>&lt;envvar&gt;</code> does not exist
 864         in the environment. <code>&lt;envvar&gt;</code> may not contain an equals sign
 865         to avoid ambiguity with <code>&lt;name&gt;</code> containing one.
 866 </p>
 867 <div class="paragraph"><p>This is useful for cases where you want to pass transitory
 868 configuration options to git, but are doing so on operating systems
 869 where other processes might be able to read your command line
 870 (e.g. <code>/proc/self/cmdline</code>), but not your environment
 871 (e.g. <code>/proc/self/environ</code>). That behavior is the default on
 872 Linux, but may not be on your system.</p></div>
 873 <div class="paragraph"><p>Note that this might add security for variables such as
 874 <code>http.extraHeader</code> where the sensitive information is part of
 875 the value, but not e.g. <code>url.&lt;base&gt;.insteadOf</code> where the
 876 sensitive information can be part of the key.</p></div>

2953         This should be a colon-separated list of absolute paths.  If
2954         set, it is a list of directories that Git should not chdir up
2955         into while looking for a repository directory (useful for
2956         excluding slow-loading network directories).  It will not
2957         exclude the current working directory or a GIT_DIR set on the
2958         command line or in the environment.  Normally, Git has to read
2959         the entries in this list and resolve any symlink that
2960         might be present in order to compare them with the current
2961         directory.  However, if even this access is slow, you
2962         can add an empty entry to the list to tell Git that the
2963         subsequent entries are not symlinks and needn&#8217;t be resolved;

2978         boundaries.  Like <code>GIT_CEILING_DIRECTORIES</code>, this will not affect

3645         which feed potentially-untrusted URLS to git commands.  See

3661 accessing local repositories (i.e., <code>file://</code> or a filesystem path), as
3662 well as over the <code>git://</code> protocol. For git-over-http, it should work
3663 automatically in most configurations, but see the discussion in
3664 <a href="git-http-backend.html">git-http-backend(1)</a>. For git-over-ssh, the ssh server may need

3667 <div class="paragraph"><p>This configuration is optional. If the variable is not propagated, then
3668 clients will fall back to the original "v0" protocol (but may miss out

3678         If this Boolean environment variable is set to false, Git will complete any requested operation without
3679         performing any optional sub-operations that require taking a lock.
3680         For example, this will prevent <code>git status</code> from refreshing the
3681         index as a side effect. This is useful for processes running in
3682         the background which do not want to cause lock contention with

3701         not an option because it would require the handles to be marked
3702         inheritable (and consequently <strong>every</strong> spawned process would
3703         inherit them, possibly blocking regular Git operations). The
3704         primary intended use case is to use named pipes for communication

3733 <div class="paragraph"><p>More detail on the following is available from the
3734 <a href="user-manual.html#git-concepts">Git concepts chapter of the
3735 user-manual</a> and <a href="gitcore-tutorial.html">gitcore-tutorial(7)</a>.</p></div>
3736 <div class="paragraph"><p>A Git project normally consists of a working directory with a ".git"
3737 subdirectory at the top level.  The .git directory contains, among other
3738 things, a compressed object database representing the complete history
3739 of the project, an "index" file which links that history to the current
3740 contents of the working tree, and named pointers into that history such
3741 as tags and branch heads.</p></div>
3742 <div class="paragraph"><p>The object database contains objects of three main types: blobs, which
3743 hold file data; trees, which point to blobs and other trees to build up
3744 directory hierarchies; and commits, which each reference a single tree
3745 and some number of parent commits.</p></div>
3746 <div class="paragraph"><p>The commit, equivalent to what other systems call a "changeset" or
3747 "version", represents a step in the project&#8217;s history, and each parent
3748 represents an immediately preceding step.  Commits with more than one
3749 parent represent merges of independent lines of development.</p></div>
3750 <div class="paragraph"><p>All objects are named by the SHA-1 hash of their contents, normally
3751 written as a string of 40 hex digits.  Such names are globally unique.
3752 The entire history leading up to a commit can be vouched for by signing
3753 just that commit.  A fourth object type, the tag, is provided for this
3754 purpose.</p></div>
3755 <div class="paragraph"><p>When first created, objects are stored in individual files, but for
3756 efficiency may later be compressed together into "pack files".</p></div>
3757 <div class="paragraph"><p>Named pointers called refs mark interesting points in history.  A ref
3758 may contain the SHA-1 name of an object or the name of another ref (the
3759 latter is called a "symbolic ref").
3760 Refs with names beginning <code>refs/head/</code> contain the SHA-1 name of the most
3761 recent commit (or "head") of a branch under development.  SHA-1 names of
3762 tags of interest are stored under <code>refs/tags/</code>.  A symbolic ref named
3763 <code>HEAD</code> contains the name of the currently checked-out branch.</p></div>
3764 <div class="paragraph"><p>The index file is initialized with a list of all paths and, for each
3765 path, a blob object and a set of attributes.  The blob object represents
3766 the contents of the file as of the head of the current branch.  The
3767 attributes (last modified time, size, etc.) are taken from the
3768 corresponding file in the working tree.  Subsequent changes to the
3769 working tree can be found by comparing these attributes.  The index may
3770 be updated with new content, and new commits may be created from the
3771 content stored in the index.</p></div>
3772 <div class="paragraph"><p>The index is also capable of storing multiple entries (called "stages")
3773 for a given pathname.  These stages are used to hold the various
3774 unmerged version of a file when a merge is in progress.</p></div>
