<p> An <i>.info</i> file is an information document created by Texinfo.
It stores documentation in a book format with chapters, sections,
and subsections and can contain up to four layers of depth.
Info documents are used for storing software help manuals and technical books.
The <code>info</code> command allows you to read that kind of files
and to search for particular information by using special flags.</p>
<pre>
Device-name:Current-position username$ info [flag] [item]
</pre>
<p>By writing the command <code>info</code> followed by nothing, as result you
will get a list of what you can do with that command.</p>
<h3>Look up for a specific string</h3>
<p>Using the <code>--apropos</code> flag followed by a string, you obtain as
output a list of all the contents which correspond to the string you wrote.</p>
<pre>
Device-name:Current-position username$ info --apropos string
</pre>
<p>If the string you inserted has nothing to do with the content of the info files,
you will get a error message. For example:</p>
<pre>
Device-name:Current-position username$ info --apropos duck
info: No available info files have `duck' in their indices.
</pre>
<h3>An help with this command</h3>
<p>Using the <code>-h</code> flag (which stands for help), you obtain as
output a brief paragraph in which are explained the features of this command.</p>
<pre>
Device-name:Current-position username$ info -h
</pre>
<h3>Visit a specific <i>.info</i> file</h3>
<p>Using the <code>-f</code> flag followed by the path and a <i>.info</i> file, you
as output obtain the content of that file.</p>
<pre>
Device-name:Current-position username$ info -f path/filename.info
</pre>
