shootout: GNU screen, tmux and dtach+dvtm

Filed under
Software

When it comes to terminal managers in Linux, it usually boils down to three choices: screen, tmux or the dtach+dvtm duo. Proponents of each often vigorously tout their solution as the best. So let's see how they compare.

The Contenders

* GNU screen is the oldest and perhaps most widely used of the terminal managers in this comparison. It has been around since the 1980s and made thousands if not millons of users' lives easier since then.

* tmux is a relative newcomer, the first release dating to late 2007. It was developed specifically with the goal of overcoming limitations in the implementation of screen.

* dvtm is best described as tiling window manager for the console. First released in late 2007 too, it lacks the disconnection/reattachment feature of the other two solutions, so it will unleash its full power only in combination with dtach which does exactly that. (Using screen/tmux with dvtm is also possible.) dtach was released in 2004.

Included with the BQ Aquaris E4.5 Ubuntu Edition are two copies of the quick-start guide (in four languages each, one of the eight being English), a charger (with a built-in two-pin continental mains plug) and a 1-metre USB-to-Micro-USB cable.

Enabling Open Source SDN and NFV in the Enterprise

On the heel of Krzanich’s announcements, Intel Software & Services Group Senior VP Doug Fisher extended Krzanich’s message to stress the importance of open source collaboration to drive industry innovation and transformation, citing OpenStack and Hadoop as prime examples.
