Process Terminal

Process Terminal

The Process plugin allows you to start a shell (or any other process) and then directly communicte to its STDIN, STDOUT, and STDERR streams.

This functionality comes indispensible when the process in question outputs (or expects as input) some binary data. For instance, if you open your regular terminal console and run netcat or openssl to connect to a web-server, and then issue a GET request to fetch some binary resource, e.g. :

$ openssl s_client -connect ioninja.com:443

GET /images/icons/ioninja-256x256.png HTTP/1.1
Host: ioninja.com

... the output will be incomprehensible due to its binary nature:

HTTP/1.1 200 OK

IO Ninja, on the other hand, is tailor-made to handle binary data elegantly and efficiently, so you will have no problem inspecting and analyzing binary output of a process (or feeding a binary request to its STDIN stream).

Another prominent feature of the Process plugin is that unlike a regular terminal console, it can separate between STDOUT and STDERR streams.
