Questions tagged [head]

DO NOT USE as this is an ambigous tag. It might refer to HTML

element, UNIX command, HTTP HEAD method. Instead use [html] for questions about html, [http-head] for questions about the HTTP HEAD method, [unix-head] for question about the UNIX head command.

The <head> element is a container for all the head elements.

The element must include a title for the document, and can include scripts, styles, meta information, and more.

The following elements can go inside the element:

<title> (this element is required in the head section)
<style>
<base>
<link>
<meta>
<script>
<noscript>

head is also a unix command which displays the first lines of a file. It's counterpart which displays the last lines is tail ().

Example: head -n 10 file will output first 10 lines of file.
