<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>
