You probably already know of existence of two Linux commands available by default across all Linux distributions scriptwhich makes a text based save of all commands executed on console and scriptreplay – which playbacks saved script command typescripts. Using this two you can save terminal sessions without problem, but in order to play them you need to have a Linux / UNIX computer at hand.
However If you want to make a short video record displaying what you have done on Linux console / terminal, you have few other options with which you can share your Linux terminal sessions on the web. In this short article I will go through 3 popular tools to do that – asciinema, showterm and termrecord.

1. Asciinema Current most popular tool to create video from Linux terminal

Here is how ASCIINEMA's website describes it:

"Asciinema is a free and open source solution for recording the terminal sessions and sharing them on the web."

apt-get –yes install python-pip

To install it with pip python package installer

pip install asciinema

Or if the machine is in DMZ secured zone and have access to the internet over a Proxy:

pip install –proxy=http://internet-proxy-host.com:8080 asciinema

It will get installed in /usr/local/bin/asciinema to make a terminal screen video capture just launch it (nomatter if it is privileged or non-privileged user):

asciinema

To finalize and upload the recorded terminal session, just type exit (to exit the shell), hopefully it will get you an upload link.

exit

You can claim authorship on video you issue:

asciinema auth

Use can then embed the new Linux terminal session video to your website.
 

2. ShowTerm – "It's showtime in a terminal near you!"

ShowTerm have same features as AsciiNema. Just like AsciiNema, what it does is it creates a record of your terminal session and then uploads it to showterm.io website, providing you a link over which you can share your terminal lesson / ascii art video / whatever with your friends. ShowTerm is written in, the world famous Ruby on Railsruby web development framework, so you will need to have ruby programming language installed before use. As showterm uses the Internet to upload video, so it is not really an option to create videos from remote terminal session on servers which are in DMZ with no access to the internet, I will explain in a little while how to create video of your terminal / console for private purpose on local server and then share it online on your own site.

a) To install ShowTerm:

– First be sure to have ruby installed:

On Debian / Ubuntu and derives deb Linux, as supersuser:

apt-get install –yes ruby curl

On CentOS / RHEL / Fedora Linux

yum -y install ruby curl

NB! curl is real requirement but as showterm.io website recommends downloading the script with it and later same curl tool is used to upload the created showterm file to http://showterm.io .

– Then to finalize install, download showterm script and make it executable

curl showterm.io/showterm > ~/bin/showterm

% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                       Dload  Upload   Total   Spent    Left  Speed
100  2007  100  2007    0     0   2908      0 –:–:– –:–:– –:–:–  8468

mkdir ~/bin
chmod +x ~/bin/showterm

This will save the script into your home folder ~/bin/showterm

b) Using showterm

To run it to create video from your terminal simply start it and do whatver you will in terminal.

~/bin/showterm

After you're done with the video you like type exit

exit

Note that if your server is behind a proxy curl will not understand proxy set inside Linux shell variable with http_proxy var, to upload the file if you're behind a proxy you will have to pass to curl –proxy setting, once you get the curl line invoked after failure to upload use something like:

curl –proxy $(echo $http_proxy)  https://showterm.herokuapp.com/scripts –data-urlencode cols=80 –data-urlencode lines=24 –data-urlencode scriptfile@/tmp/yCudk.script –data-urlencode timingfile@/tmp/lkiXP.timing

Where assuming proxy is defined already inside http_proxy shell variable.

 

3. Creating video from your terminal / console on Linux for local (private) use with TermRecord

In my humble view TermRecord is the most awesome of all the 3, as it allows you to make records with an own generated Javascript based video player and allows you to keep the videos on your own side, guaranteeing you independence of external services. Its
 

pip install TermRecord

TermRecord -o /tmp/session.html

 

You can further access the video in a local browser in Firefox / Chrome / Epiphany type in URL address bar:

/tmp/session.html to play the video

create-video-from-terminal-console-on-gnu-linux-howto-screenshot-with-termrecord

TermRecord uses term.js javascript to create the video web player and play the video which is directly encoded inside session.html.
If you want to share the video online, place it on your webserver and you're done 🙂
