As a member of the Fedora Linux QA team, I sometimes find myself executing a bunch of commands that I want to broadcast to other developers. If you’ve ever used a terminal multiplexer<\/a> like tmux<\/a> or GNU Screen<\/a>, you might think that that’s a relatively easy task. But not all of the people I want to see my demonstration are connecting to my terminal session from a laptop or desktop. Some might have casually opened it from their phone browser\u2014which they can readily do because I use tmate<\/a>.<\/p>\n

Linux terminal sharing with tmate<\/h2>\n

Watching someone else work in a Linux terminal is very educational. You can learn new commands, new workflows, or new ways to debug and automate. But it can be difficult to capture what you’re seeing so you can try it yourself later. You might resort to taking screenshots or a screen recording of a shared terminal session so you can type out each command later. The only other option is for the person demonstrating the commands to record the session using a tool like Asciinema<\/a> or script and scriptreplay<\/a>.<\/p>\n

But with tmate, a user can share a terminal either in read-only mode or over SSH. Both the SSH and the read-only session can be accessed through a terminal or as an HTML webpage.<\/p>\n

I use read-only mode when I’m onboarding people for the Fedora QA team because I need to run commands and show the output, but with tmate, folks can keep notes by copying and pasting from their browser to a text editor.<\/p>\n

Linux tmate in action<\/h2>\n

On Linux, you can install tmate with your package manager. For instance, on Fedora:<\/p>\n

\n$ <\/span>sudo<\/span> dnf install<\/span> tmate<\/code><\/span><\/pre>\n
On Debian and similar distributions:<\/p>\n
\n$ <\/span>sudo<\/span> apt install<\/span> tmate<\/code><\/span><\/pre>\n
\n

Once installed, start tmate:<\/p>\n
\n$ <\/span>tmate<\/code><\/span><\/pre>\n
When tmate launches, links are generated to provide access to your terminal session over HTTP and SSH. Each protocol features a read-only option as well as a reverse SSH session.<\/p>\n
Here’s what a web session looks like:<\/p>\n

Tmate’s web console is HTML5, so, as a result, a user can copy the entire screen and paste it into a terminal to run the same commands.<\/p>\n<\/p>\n

Keeping a session alive<\/h2>\n
You may wonder what happens if you accidentally close your terminal. You may also wonder about sharing your terminal with a different console application. After all, tmate is a multiplexer, so it should be able to keep sessions alive, detach and re-attach to a session, and so on.<\/p>\n
And of course, that’s exactly what tmate can do. If you’ve ever used tmux, this is probably pretty familiar.<\/p>\n
\n$ <\/span>tmate -F<\/span> -n<\/span> web new-session vi<\/span>\u00a0 console<\/code><\/span><\/pre>\n
This command opens up new-session<\/code> in Vi, and the -F <\/code>option ensures that the session re-spawns even when closed.<\/p>\n

Social multiplexing<\/h2>\n
Tmate gives you the freedom of tmux or GNU Screen plus the ability to share your sessions with others. It’s a valuable tool for teaching other users how to use a terminal, demonstrating the function of a new command, or debugging unexpected behavior. It’s open source, so give it a try!<\/p>\n<\/div>\n
