Recording and Sharing Terminal Sessions with Asciinema
Asciinema is an open-source tool for recording and sharing terminal sessions.
Instead of heavy video files, it saves text-based replays that can be played back interactively — perfect for tutorials, demos, and blog posts.
Install Asciinema
On Ubuntu 24.04 LTS:
sudo apt update
sudo apt install asciinema -y
Verify the installation:
asciinema --version
Record Your First Session
Start recording:
asciinema rec
You’ll see:
~ Asciinema recorder v3.0.0
~ Press <Ctrl-D> or type 'exit' when you're done recording.
Everything you type in the terminal is recorded until you exit with Ctrl+D or exit.
Upload and Share
After finishing the recording, you can upload it to Asciinema:
asciinema upload your-session.cast
You’ll get a link like:
