A simple script for embedding HTML content - just pipe to to stdin:
echo 'E = mc<sup>2</sup>' | hcat
displays: E = mc2.
This script “prints” the contents of the named image file to domterm.
This uses a “data:” URI with the file contents sent directly to domterm, so it works when working remotely.
imgcat[-] [n--]...attrname=attrvaluefilename
The filename must be a file that can be displayed
by an HTML <img> element, most commonly a png or jpg file.
-n
Do not append a newline.
--attrname=attrvalue
Specify the given attribute; for example: --height=200.
Valid attrnames are the following, which
are specified in the HTML specification:
alt, longdesc, height, width, border, hspace, vspace, class.
