What Others Think

Without augmenting the txt2html arguments or template, this is similar to (echo ""; lsof -nPi; echo "") > lsof.html

Compare both in a browser and you will see that txt2html is superior.

txt2html just puts '' around the output of lsof, and makes hyperlinks of the entries in the 'NAME' column, for host/port pairs that do not talk HTTP so the links are not useful. Installing HTML::TextToHTML for this is inefficient -- you can do the same with ( echo '<pre>'; sudo lsof -nPi; echo '</pre>' ) >/tmp/lsof.html ... but why load up the bulk of a web browser for viewing text/plain document?

I used to rely on echo for this and it was painful. HTML is far superior and is simple to install: cpan App::cpanminus cpanm HTML::TextToHTML From man page: DESCRIPTION txt2html converts plain text files to HTML. It supports headings, tables, lists, simple character markup, and hyperlinking, and is highly customizable. It recognizes some of the apparent structure of the source document (mostly whitespace and typographic layout), and attempts to mark that structure explicitly using HTML. The purpose for this tool is to provide an easier way of converting existing text documents to HTML format. One can use txt2html as a filter, outputting the result to STDOUT, or to a given file. One can define options in a config file as well as on the command-line.
