<title>Command line usage</title>
<p>
If you start <app>Meld</app> from the command line, you can tell it what to do when it starts.
</p>
<p>
For a two- or three-way <link xref="file-mode">file comparison</link>, start <app>Meld</app> with
<cmd>meld <var>file1</var> <var>file2</var></cmd> or
<cmd>meld <var>file1</var> <var>file2</var> <var>file3</var></cmd> respectively.
</p>
<p>
For a two- or three-way <link xref="folder-mode">directory comparison</link>, start <app>Meld</app> with
<cmd>meld <var>dir1</var> <var>dir2</var></cmd> or <cmd>meld <var>dir1</var> <var>dir2</var> <var>dir3</var></cmd>.
</p>
<p>
You can start a <link xref="vc-mode">version control</link> comparison by just
giving a single argument; if that file or directory is managed by a
<link xref="vc-supported">recognized version control system</link>, it will
start a version control comparison on that argument. For example,
<cmd>meld .</cmd> would start a version control view of the current directory.
</p>
<note>
<p>
Run <cmd>meld --help</cmd> for a list of all command line options.
