The output of lsof is piped to txt2html which converts it to html.

# Perl module HTML::TextToHTML needed


There is 1 alternative - vote for the best!

Terminal - Alternatives
lsof -nPi | txt2html > ~/lsof.html | gnome-open lsof.html

In addition to generating the current connections, it also opens then in your default browser on gnome.

Know a better way?

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.

Comment by zlemini 351 weeks and 3 days ago

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?

Comment by Mozai 351 weeks and 2 days ago

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:


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.
