<h2>NAME</h2>
<div class="sectionbody">
<p>git-cvsimport -
Salvage your data out of another SCM people love to hate
</p>
</div>
</div>
<h2>SYNOPSIS</h2>
<div class="sectionbody">
<div class="verseblock">
<div class="content"><em>git cvsimport</em> [-o &lt;branch-for-HEAD&gt;] [-h] [-v] [-d &lt;CVSROOT&gt;]
[-A &lt;author-conv-file&gt;] [-p &lt;options-for-cvsps&gt;] [-P &lt;file&gt;]
[-C &lt;git_repository&gt;] [-z &lt;fuzz&gt;] [-i] [-k] [-u] [-s &lt;subst&gt;]
[-a] [-m] [-M &lt;regex&gt;] [-S &lt;regex&gt;] [-L &lt;commitlimit&gt;]
[-r &lt;remote&gt;] [&lt;CVS_module&gt;]</div></div>
</div>
<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="para"><p>Imports a CVS repository into git. It will either create a new
repository, or incrementally import into an existing one.</p></div>
<div class="para"><p>Splitting the CVS log into patch sets is done by <em>cvsps</em>.
At least version 2.1 is required.</p></div>
<div class="para"><p>You should <strong>never</strong> do any work of your own on the branches that are
created by <em>git-cvsimport</em>. By default initial import will create and populate a
"master" branch from the CVS repository's main branch which you're free
to work with; after that, you need to <em>git-merge</em> incremental imports, or
any CVS branches, yourself. It is advisable to specify a named remote via
-r to separate and protect the incoming branches.</p></div>
<div class="para"><p>If you intend to set up a shared public repository that all developers can
read/write, or if you want to use <a href="git-cvsserver.html">git-cvsserver(1)</a>, then you
probably want to make a bare clone of the imported repository,
and use the clone as the shared repository.
See <a href="gitcvs-migration.html">gitcvs-migration(7)</a>.</p></div>
</div>
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="vlist"><dl>
<dt>
-v
</dt>
<dd>
<p>
Verbosity: let <em>cvsimport</em> report what it is doing.
</p>
</dd>
<dt>
-d &lt;CVSROOT&gt;
</dt>
<dd>
<p>
The root of the CVS archive. May be local (a simple path) or remote;
currently, only the :local:, :ext: and :pserver: access methods
are supported. If not given, <em>git-cvsimport</em> will try to read it
from <tt>CVS/Root</tt>. If no such file exists, it checks for the
<tt>CVSROOT</tt> environment variable.
</p>
</dd>
<dt>
&lt;CVS_module&gt;
</dt>
<dd>
<p>
The CVS module you want to import. Relative to &lt;CVSROOT&gt;.
If not given, <em>git-cvsimport</em> tries to read it from
<tt>CVS/Repository</tt>.
</p>
</dd>
<dt>
-C &lt;target-dir&gt;
</dt>
<dd>
<p>
The git repository to import to. If the directory doesn't
exist, it will be created. Default is the current directory.
</p>
</dd>
<dt>
-r &lt;remote&gt;
</dt>
<dd>
<p>
The git remote to import this CVS repository into.
Moves all CVS branches into remotes/&lt;remote&gt;/&lt;branch&gt;
akin to the <em>git-clone</em> "--use-separate-remote" option.
</p>
</dd>
<dt>
-o &lt;branch-for-HEAD&gt;
</dt>
<dd>
<p>
When no remote is specified (via -r) the <em>HEAD</em> branch
from CVS is imported to the <em>origin</em> branch within the git
repository, as <em>HEAD</em> already has a special meaning for git.
When a remote is specified the <em>HEAD</em> branch is named
remotes/&lt;remote&gt;/master mirroring <em>git-clone</em> behaviour.
Use this option if you want to import into a different
branch.
</p>
<div class="para"><p>Use <em>-o master</em> for continuing an import that was initially done by
the old cvs2git tool.</p></div>
</dd>
<dt>
-i
</dt>
<dd>
<p>
Import-only: don't perform a checkout after importing. This option
ensures the working directory and index remain untouched and will
not create them if they do not exist.
</p>
</dd>
<dt>
-k
</dt>
<dd>
<p>
Kill keywords: will extract files with <em>-kk</em> from the CVS archive
to avoid noisy changesets. Highly recommended, but off by default
to preserve compatibility with early imported trees.
</p>
</dd>
<dt>
-u
</dt>
<dd>
<p>
Convert underscores in tag and branch names to dots.
</p>
</dd>
<dt>
-s &lt;subst&gt;
</dt>
<dd>
<p>
Substitute the character "/" in branch names with &lt;subst&gt;
</p>
</dd>
<dt>
-p &lt;options-for-cvsps&gt;
</dt>
<dd>
<p>
Additional options for cvsps.
The options <em>-u</em> and <em>-A</em> are implicit and should not be used here.
</p>
<div class="para"><p>If you need to pass multiple options, separate them with a comma.</p></div>
</dd>
<dt>
-z &lt;fuzz&gt;
</dt>
<dd>
<p>
Pass the timestamp fuzz factor to cvsps, in seconds. If unset,
cvsps defaults to 300s.
</p>
</dd>
<dt>
-P &lt;cvsps-output-file&gt;
</dt>
<dd>
<p>
Instead of calling cvsps, read the provided cvsps output file. Useful
for debugging or when cvsps is being handled outside cvsimport.
</p>
</dd>
<dt>
-m
</dt>
<dd>
<p>
Attempt to detect merges based on the commit message. This option
will enable default regexes that try to capture the source
branch name from the commit message.
</p>
</dd>
<dt>
-M &lt;regex&gt;
</dt>
<dd>
<p>
Attempt to detect merges based on the commit message with a custom
regex. It can be used with <em>-m</em> to enable the default regexes
as well. You must escape forward slashes.
</p>
<div class="para"><p>The regex must capture the source branch name in $1.</p></div>
<div class="para"><p>This option can be used several times to provide several detection regexes.</p></div>
</dd>
<dt>
-S &lt;regex&gt;
</dt>
<dd>
<p>
Skip paths matching the regex.
</p>
</dd>
<dt>
-a
</dt>
<dd>
<p>
Import all commits, including recent ones. cvsimport by default
skips commits that have a timestamp less than 10 minutes ago.
</p>
</dd>
<dt>
-L &lt;limit&gt;
</dt>
<dd>
<p>
Limit the number of commits imported. Workaround for cases where
cvsimport leaks memory.
</p>
</dd>
<dt>
-A &lt;author-conv-file&gt;
</dt>
<dd>
<p>
CVS by default uses the Unix username when writing its
commit logs. Using this option and an author-conv-file
in this format
</p>
<div class="listingblock">
<div class="content">
<pre><tt> exon=Andreas Ericsson &lt;ae@op5.se&gt;
spawn=Simon Pawn &lt;spawn@frog-pond.org&gt;
</tt></pre>
</div></div>
<div class="para"><p><em>git-cvsimport</em> will make it appear as those authors had
their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly
all along.</p></div>
<div class="para"><p>For convenience, this data is saved to <tt>$GIT_DIR/cvs-authors</tt>
each time the <em>-A</em> option is provided and read from that same
file each time <em>git-cvsimport</em> is run.</p></div>
<div class="para"><p>It is not recommended to use this feature if you intend to
export changes back to CVS again later with
<em>git-cvsexportcommit</em>.</p></div>
</dd>
<dt>
-h
</dt>
<dd>
<p>
Print a short usage message and exit.
</p>
</dd>
</dl></div>
