| <div class="sectionbody"> | |
| <div class="paragraph"><p>Hooks are programs you can place in a hooks directory to trigger | |
| actions at certain points in git’s execution. Hooks that don’t have | |
| the executable bit set are ignored.</p></div> | |
| <div class="paragraph"><p>By default the hooks directory is <code>$GIT_DIR/hooks</code>, but that can be | |
| changed via the <code>core.hooksPath</code> configuration variable (see | |
| <a href="git-config.html">git-config(1)</a>).</p></div> | |
| <div class="paragraph"><p>Before Git invokes a hook, it changes its working directory to either | |
| $GIT_DIR in a bare repository or the root of the working tree in a non-bare | |
| repository. An exception are hooks triggered during a push (<em>pre-receive</em>, | |
| <em>update</em>, <em>post-receive</em>, <em>post-update</em>, <em>push-to-checkout</em>) which are always | |
| executed in $GIT_DIR.</p></div> | |
| <div class="paragraph"><p>Hooks can get their arguments via the environment, command-line | |
| arguments, and stdin. See the documentation for each hook below for | |
| details.</p></div> | |
| <div class="paragraph"><p><code>git init</code> may copy hooks to the new repository, depending on its | |
| configuration. See the "TEMPLATE DIRECTORY" section in | |

| <div class="sectionbody"> | |
| <div class="sect2"> | |
| <h3 id="_applypatch_msg">applypatch-msg</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-am.html">git-am(1)</a>. It takes a single | |
| parameter, the name of the file that holds the proposed commit | |
| log message. Exiting with a non-zero status causes <code>git am</code> to abort | |
| before applying the patch.</p></div> | |
| <div class="paragraph"><p>The hook is allowed to edit the message file in place, and can | |
| be used to normalize the message into some project standard | |
| format. It can also be used to refuse the commit after inspecting | |
| the message file.</p></div> | |
| <div class="paragraph"><p>The default <em>applypatch-msg</em> hook, when enabled, runs the | |
| <em>commit-msg</em> hook, if the latter is enabled.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_pre_applypatch">pre-applypatch</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-am.html">git-am(1)</a>. It takes no parameter, and is | |
| invoked after the patch is applied, but before a commit is made.</p></div> | |
| <div class="paragraph"><p>If it exits with non-zero status, then the working tree will not be | |
| committed after applying the patch.</p></div> | |
| <div class="paragraph"><p>It can be used to inspect the current working tree and refuse to | |
| make a commit if it does not pass certain test.</p></div> | |
| <div class="paragraph"><p>The default <em>pre-applypatch</em> hook, when enabled, runs the | |
| <em>pre-commit</em> hook, if the latter is enabled.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_post_applypatch">post-applypatch</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-am.html">git-am(1)</a>. It takes no parameter, | |
| and is invoked after the patch is applied and a commit is made.</p></div> | |
| <div class="paragraph"><p>This hook is meant primarily for notification, and cannot affect | |
| the outcome of <code>git am</code>.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_pre_commit">pre-commit</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-commit.html">git-commit(1)</a>, and can be bypassed | |
| with the <code>--no-verify</code> option. It takes no parameters, and is | |
| invoked before obtaining the proposed commit log message and | |
| making a commit. Exiting with a non-zero status from this script | |
| causes the <code>git commit</code> command to abort before creating a commit.</p></div> | |
| <div class="paragraph"><p>The default <em>pre-commit</em> hook, when enabled, catches introduction | |
| of lines with trailing whitespaces and aborts the commit when | |
| such a line is found.</p></div> | |
| <div class="paragraph"><p>All the <code>git commit</code> hooks are invoked with the environment | |
| variable <code>GIT_EDITOR=:</code> if the command will not bring up an editor | |
| to modify the commit message.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_prepare_commit_msg">prepare-commit-msg</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-commit.html">git-commit(1)</a> right after preparing the | |
| default log message, and before the editor is started.</p></div> | |
| <div class="paragraph"><p>It takes one to three parameters. The first is the name of the file | |
| that contains the commit log message. The second is the source of the commit | |
| message, and can be: <code>message</code> (if a <code>-m</code> or <code>-F</code> option was | |
| given); <code>template</code> (if a <code>-t</code> option was given or the | |
| configuration option <code>commit.template</code> is set); <code>merge</code> (if the | |
| commit is a merge or a <code>.git/MERGE_MSG</code> file exists); <code>squash</code> | |
| (if a <code>.git/SQUASH_MSG</code> file exists); or <code>commit</code>, followed by | |
| a commit SHA-1 (if a <code>-c</code>, <code>-C</code> or <code>--amend</code> option was given).</p></div> | |
| <div class="paragraph"><p>If the exit status is non-zero, <code>git commit</code> will abort.</p></div> | |
| <div class="paragraph"><p>The purpose of the hook is to edit the message file in place, and | |
| it is not suppressed by the <code>--no-verify</code> option. A non-zero exit | |
| means a failure of the hook and aborts the commit. It should not | |
| be used as replacement for pre-commit hook.</p></div> | |
| <div class="paragraph"><p>The sample <code>prepare-commit-msg</code> hook that comes with Git removes the | |
| help message found in the commented portion of the commit template.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_commit_msg">commit-msg</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-commit.html">git-commit(1)</a> and <a href="git-merge.html">git-merge(1)</a>, and can be | |
| bypassed with the <code>--no-verify</code> option. It takes a single parameter, | |
| the name of the file that holds the proposed commit log message. | |
| Exiting with a non-zero status causes the command to abort.</p></div> | |
| <div class="paragraph"><p>The hook is allowed to edit the message file in place, and can be used | |
| to normalize the message into some project standard format. It | |
| can also be used to refuse the commit after inspecting the message | |
| file.</p></div> | |
| <div class="paragraph"><p>The default <em>commit-msg</em> hook, when enabled, detects duplicate | |
| "Signed-off-by" lines, and aborts the commit if one is found.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_post_commit">post-commit</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-commit.html">git-commit(1)</a>. It takes no parameters, and is | |
| invoked after a commit is made.</p></div> | |
| <div class="paragraph"><p>This hook is meant primarily for notification, and cannot affect | |
| the outcome of <code>git commit</code>.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_pre_rebase">pre-rebase</h3> | |
| <div class="paragraph"><p>This hook is called by <a href="git-rebase.html">git-rebase(1)</a> and can be used to prevent a | |
| branch from getting rebased. The hook may be called with one or | |
| two parameters. The first parameter is the upstream from which | |
| the series was forked. The second parameter is the branch being | |
| rebased, and is not set when rebasing the current branch.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_post_checkout">post-checkout</h3> | |
| <div class="paragraph"><p>This hook is invoked when a <a href="git-checkout.html">git-checkout(1)</a> is run after having updated the | |
| worktree. The hook is given three parameters: the ref of the previous HEAD, | |
| the ref of the new HEAD (which may or may not have changed), and a flag | |
| indicating whether the checkout was a branch checkout (changing branches, | |
| flag=1) or a file checkout (retrieving a file from the index, flag=0). | |
| This hook cannot affect the outcome of <code>git checkout</code>.</p></div> | |
| <div class="paragraph"><p>It is also run after <a href="git-clone.html">git-clone(1)</a>, unless the <code>--no-checkout</code> (<code>-n</code>) option is | |
| used. The first parameter given to the hook is the null-ref, the second the | |
| ref of the new HEAD and the flag is always 1. Likewise for <code>git worktree add</code> | |
| unless <code>--no-checkout</code> is used.</p></div> | |
| <div class="paragraph"><p>This hook can be used to perform repository validity checks, auto-display | |
| differences from the previous HEAD if different, or set working dir metadata | |
| properties.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_post_merge">post-merge</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-merge.html">git-merge(1)</a>, which happens when a <code>git pull</code> | |
| is done on a local repository. The hook takes a single parameter, a status | |
| flag specifying whether or not the merge being done was a squash merge. | |
| This hook cannot affect the outcome of <code>git merge</code> and is not executed, | |
| if the merge failed due to conflicts.</p></div> | |
| <div class="paragraph"><p>This hook can be used in conjunction with a corresponding pre-commit hook to | |
| save and restore any form of metadata associated with the working tree | |
| (e.g.: permissions/ownership, ACLS, etc). See contrib/hooks/setgitperms.perl | |
| for an example of how to do this.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_pre_push">pre-push</h3> | |
| <div class="paragraph"><p>This hook is called by <a href="git-push.html">git-push(1)</a> and can be used to prevent | |
| a push from taking place. The hook is called with two parameters | |
| which provide the name and location of the destination remote, if a | |
| named remote is not being used both values will be the same.</p></div> | |
| <div class="paragraph"><p>Information about what is to be pushed is provided on the hook’s standard | |
| input with lines of the form:</p></div> | |
| <div class="literalblock"> | |
| <div class="content"> | |
| <pre><code><local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>For instance, if the command <code>git push origin master:foreign</code> were run the | |
| hook would receive a line like the following:</p></div> | |
| <div class="literalblock"> | |
| <div class="content"> | |
| <pre><code>refs/heads/master 67890 refs/heads/foreign 12345</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>although the full, 40-character SHA-1s would be supplied. If the foreign ref | |
| does not yet exist the <code><remote SHA-1></code> will be 40 <code>0</code>. If a ref is to be | |
| deleted, the <code><local ref></code> will be supplied as <code>(delete)</code> and the <code><local | |
| SHA-1></code> will be 40 <code>0</code>. If the local commit was specified by something other | |
| than a name which could be expanded (such as <code>HEAD~</code>, or a SHA-1) it will be | |
| supplied as it was originally given.</p></div> | |
| <div class="paragraph"><p>If this hook exits with a non-zero status, <code>git push</code> will abort without | |
| pushing anything. Information about why the push is rejected may be sent | |
| to the user by writing to standard error.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="pre-receive">pre-receive</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-receive-pack.html">git-receive-pack(1)</a> when it reacts to | |
| <code>git push</code> and updates reference(s) in its repository. | |
| Just before starting to update refs on the remote repository, the | |
| pre-receive hook is invoked. Its exit status determines the success | |
| or failure of the update.</p></div> | |
| <div class="paragraph"><p>This hook executes once for the receive operation. It takes no | |
| arguments, but for each ref to be updated it receives on standard | |
| input a line of the format:</p></div> | |
| <div class="literalblock"> | |
| <div class="content"> | |
| <pre><code><old-value> SP <new-value> SP <ref-name> LF</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>where <code><old-value></code> is the old object name stored in the ref, | |
| <code><new-value></code> is the new object name to be stored in the ref and | |
| <code><ref-name></code> is the full name of the ref. | |
| When creating a new ref, <code><old-value></code> is 40 <code>0</code>.</p></div> | |
| <div class="paragraph"><p>If the hook exits with non-zero status, none of the refs will be | |
| updated. If the hook exits with zero, updating of individual refs can | |
| still be prevented by the <a href="#update"><em>update</em></a> hook.</p></div> | |
| <div class="paragraph"><p>Both standard output and standard error output are forwarded to | |
| <code>git send-pack</code> on the other end, so you can simply <code>echo</code> messages | |
| for the user.</p></div> | |
| <div class="paragraph"><p>The number of push options given on the command line of | |
| <code>git push --push-option=...</code> can be read from the environment | |
| variable <code>GIT_PUSH_OPTION_COUNT</code>, and the options themselves are | |
| found in <code>GIT_PUSH_OPTION_0</code>, <code>GIT_PUSH_OPTION_1</code>,… | |
| If it is negotiated to not use the push options phase, the | |
| environment variables will not be set. If the client selects | |
| to use push options, but doesn’t transmit any, the count variable | |
| will be set to zero, <code>GIT_PUSH_OPTION_COUNT=0</code>.</p></div> | |
| <div class="paragraph"><p>See the section on "Quarantine Environment" in | |
| <a href="git-receive-pack.html">git-receive-pack(1)</a> for some caveats.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="update">update</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-receive-pack.html">git-receive-pack(1)</a> when it reacts to | |
| <code>git push</code> and updates reference(s) in its repository. | |
| Just before updating the ref on the remote repository, the update hook | |
| is invoked. Its exit status determines the success or failure of | |
| the ref update.</p></div> | |
| <div class="paragraph"><p>The hook executes once for each ref to be updated, and takes | |
| three parameters:</p></div> | |
| <div class="ulist"><ul> | |
| <li> | |
| <p> | |
| the name of the ref being updated, | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| the old object name stored in the ref, | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| and the new object name to be stored in the ref. | |
| </p> | |
| </li> | |
| </ul></div> | |
| <div class="paragraph"><p>A zero exit from the update hook allows the ref to be updated. | |
| Exiting with a non-zero status prevents <code>git receive-pack</code> | |
| from updating that ref.</p></div> | |
| <div class="paragraph"><p>This hook can be used to prevent <em>forced</em> update on certain refs by | |
| making sure that the object name is a commit object that is a | |
| descendant of the commit object named by the old object name. | |
| That is, to enforce a "fast-forward only" policy.</p></div> | |
| <div class="paragraph"><p>It could also be used to log the old..new status. However, it | |
| does not know the entire set of branches, so it would end up | |
| firing one e-mail per ref when used naively, though. The | |
| <a href="#post-receive"><em>post-receive</em></a> hook is more suited to that.</p></div> | |
| <div class="paragraph"><p>In an environment that restricts the users' access only to git | |
| commands over the wire, this hook can be used to implement access | |
| control without relying on filesystem ownership and group | |
| membership. See <a href="git-shell.html">git-shell(1)</a> for how you might use the login | |
| shell to restrict the user’s access to only git commands.</p></div> | |
| <div class="paragraph"><p>Both standard output and standard error output are forwarded to | |
| <code>git send-pack</code> on the other end, so you can simply <code>echo</code> messages | |
| for the user.</p></div> | |
| <div class="paragraph"><p>The default <em>update</em> hook, when enabled—and with | |
| <code>hooks.allowunannotated</code> config option unset or set to false—prevents | |
| unannotated tags to be pushed.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="post-receive">post-receive</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-receive-pack.html">git-receive-pack(1)</a> when it reacts to | |
| <code>git push</code> and updates reference(s) in its repository. | |
| It executes on the remote repository once after all the refs have | |
| been updated.</p></div> | |
| <div class="paragraph"><p>This hook executes once for the receive operation. It takes no | |
| arguments, but gets the same information as the | |
| <a href="#pre-receive"><em>pre-receive</em></a> | |
| hook does on its standard input.</p></div> | |
| <div class="paragraph"><p>This hook does not affect the outcome of <code>git receive-pack</code>, as it | |
| is called after the real work is done.</p></div> | |
| <div class="paragraph"><p>This supersedes the <a href="#post-update"><em>post-update</em></a> hook in that it gets | |
| both old and new values of all the refs in addition to their | |
| names.</p></div> | |
| <div class="paragraph"><p>Both standard output and standard error output are forwarded to | |
| <code>git send-pack</code> on the other end, so you can simply <code>echo</code> messages | |
| for the user.</p></div> | |
| <div class="paragraph"><p>The default <em>post-receive</em> hook is empty, but there is | |
| a sample script <code>post-receive-email</code> provided in the <code>contrib/hooks</code> | |
| directory in Git distribution, which implements sending commit | |
| emails.</p></div> | |
| <div class="paragraph"><p>The number of push options given on the command line of | |
| <code>git push --push-option=...</code> can be read from the environment | |
| variable <code>GIT_PUSH_OPTION_COUNT</code>, and the options themselves are | |
| found in <code>GIT_PUSH_OPTION_0</code>, <code>GIT_PUSH_OPTION_1</code>,… | |
| If it is negotiated to not use the push options phase, the | |
| environment variables will not be set. If the client selects | |
| to use push options, but doesn’t transmit any, the count variable | |
| will be set to zero, <code>GIT_PUSH_OPTION_COUNT=0</code>.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="post-update">post-update</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-receive-pack.html">git-receive-pack(1)</a> when it reacts to | |
| <code>git push</code> and updates reference(s) in its repository. | |
| It executes on the remote repository once after all the refs have | |
| been updated.</p></div> | |
| <div class="paragraph"><p>It takes a variable number of parameters, each of which is the | |
| name of ref that was actually updated.</p></div> | |
| <div class="paragraph"><p>This hook is meant primarily for notification, and cannot affect | |
| the outcome of <code>git receive-pack</code>.</p></div> | |
| <div class="paragraph"><p>The <em>post-update</em> hook can tell what are the heads that were pushed, | |
| but it does not know what their original and updated values are, | |
| so it is a poor place to do log old..new. The | |
| <a href="#post-receive"><em>post-receive</em></a> hook does get both original and | |
| updated values of the refs. You might consider it instead if you need | |
| them.</p></div> | |
| <div class="paragraph"><p>When enabled, the default <em>post-update</em> hook runs | |
| <code>git update-server-info</code> to keep the information used by dumb | |
| transports (e.g., HTTP) up to date. If you are publishing | |
| a Git repository that is accessible via HTTP, you should | |
| probably enable this hook.</p></div> | |
| <div class="paragraph"><p>Both standard output and standard error output are forwarded to | |
| <code>git send-pack</code> on the other end, so you can simply <code>echo</code> messages | |
| for the user.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_push_to_checkout">push-to-checkout</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-receive-pack.html">git-receive-pack(1)</a> when it reacts to | |
| <code>git push</code> and updates reference(s) in its repository, and when | |
| the push tries to update the branch that is currently checked out | |
| and the <code>receive.denyCurrentBranch</code> configuration variable is set to | |
| <code>updateInstead</code>. Such a push by default is refused if the working | |
| tree and the index of the remote repository has any difference from | |
| the currently checked out commit; when both the working tree and the | |
| index match the current commit, they are updated to match the newly | |
| pushed tip of the branch. This hook is to be used to override the | |
| default behaviour.</p></div> | |
| <div class="paragraph"><p>The hook receives the commit with which the tip of the current | |
| branch is going to be updated. It can exit with a non-zero status | |
| to refuse the push (when it does so, it must not modify the index or | |
| the working tree). Or it can make any necessary changes to the | |
| working tree and to the index to bring them to the desired state | |
| when the tip of the current branch is updated to the new commit, and | |
| exit with a zero status.</p></div> | |
| <div class="paragraph"><p>For example, the hook can simply run <code>git read-tree -u -m HEAD "$1"</code> | |
| in order to emulate <code>git fetch</code> that is run in the reverse direction | |
| with <code>git push</code>, as the two-tree form of <code>git read-tree -u -m</code> is | |
| essentially the same as <code>git checkout</code> that switches branches while | |
| keeping the local changes in the working tree that do not interfere | |
| with the difference between the branches.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_pre_auto_gc">pre-auto-gc</h3> | |
| <div class="paragraph"><p>This hook is invoked by <code>git gc --auto</code> (see <a href="git-gc.html">git-gc(1)</a>). It | |
| takes no parameter, and exiting with non-zero status from this script | |
| causes the <code>git gc --auto</code> to abort.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_post_rewrite">post-rewrite</h3> | |
| <div class="paragraph"><p>This hook is invoked by commands that rewrite commits | |
| (<a href="git-commit.html">git-commit(1)</a> when called with <code>--amend</code> and | |
| <a href="git-rebase.html">git-rebase(1)</a>; currently <code>git filter-branch</code> does <em>not</em> call | |
| it!). Its first argument denotes the command it was invoked by: | |
| currently one of <code>amend</code> or <code>rebase</code>. Further command-dependent | |
| arguments may be passed in the future.</p></div> | |
| <div class="paragraph"><p>The hook receives a list of the rewritten commits on stdin, in the | |
| format</p></div> | |
| <div class="literalblock"> | |
| <div class="content"> | |
| <pre><code><old-sha1> SP <new-sha1> [ SP <extra-info> ] LF</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>The <em>extra-info</em> is again command-dependent. If it is empty, the | |
| preceding SP is also omitted. Currently, no commands pass any | |
| <em>extra-info</em>.</p></div> | |
| <div class="paragraph"><p>The hook always runs after the automatic note copying (see | |
| "notes.rewrite.<command>" in <a href="git-config.html">git-config(1)</a>) has happened, and | |
| thus has access to these notes.</p></div> | |
| <div class="paragraph"><p>The following command-specific comments apply:</p></div> | |
| <div class="dlist"><dl> | |
| <dt class="hdlist1"> | |
| rebase | |
| </dt> | |
| <dd> | |
| <p> | |
| For the <em>squash</em> and <em>fixup</em> operation, all commits that were | |
| squashed are listed as being rewritten to the squashed commit. | |
| This means that there will be several lines sharing the same | |
| <em>new-sha1</em>. | |
| </p> | |
| <div class="paragraph"><p>The commits are guaranteed to be listed in the order that they were | |
| processed by rebase.</p></div> | |

| <div class="sect2"> | |
| <h3 id="_sendemail_validate">sendemail-validate</h3> | |
| <div class="paragraph"><p>This hook is invoked by <a href="git-send-email.html">git-send-email(1)</a>. It takes a single parameter, | |
| the name of the file that holds the e-mail to be sent. Exiting with a | |
| non-zero status causes <code>git send-email</code> to abort before sending any | |
| e-mails.</p></div> | |
| </div> | |
| <div class="sect2"> | |
| <h3 id="_fsmonitor_watchman">fsmonitor-watchman</h3> | |
| <div class="paragraph"><p>This hook is invoked when the configuration option <code>core.fsmonitor</code> is | |
| set to <code>.git/hooks/fsmonitor-watchman</code>. It takes two arguments, a version | |
| (currently 1) and the time in elapsed nanoseconds since midnight, | |
| January 1, 1970.</p></div> | |
| <div class="paragraph"><p>The hook should output to stdout the list of all files in the working | |
| directory that may have changed since the requested time. The logic | |
| should be inclusive so that it does not miss any potential changes. | |
| The paths should be relative to the root of the working directory | |
| and be separated by a single NUL.</p></div> | |
| <div class="paragraph"><p>It is OK to include files which have not actually changed. All changes | |
| including newly-created and deleted files should be included. When | |
| files are renamed, both the old and the new name should be included.</p></div> | |
| <div class="paragraph"><p>Git will limit what files it checks for changes as well as which | |
| directories are checked for untracked files based on the path names | |
| given.</p></div> | |
| <div class="paragraph"><p>An optimized way to tell git "all files have changed" is to return | |
| the filename <code>/</code>.</p></div> | |
| <div class="paragraph"><p>The exit status determines whether git will use the data from the | |
| hook to limit its search. On error, it will fall back to verifying | |
| all files and folders.</p></div> | |
