asciinema CLI

Build Status

Command line client (terminal recorder) for asciinema.org service.


On Linux and Mac OS X, the easiest way to install asciinema recorder is to run the following shell command:

curl https://asciinema.org/install | sh

This script will download the latest asciinema recorder binary for your platform, and install it in your $PATH.

Other installation options, including distro specific packages (Ubuntu, Fedora, Arch Linux, Gentoo), are also available.

Building from source

To build asciinema from source you need to have Go development environment set up.

Following the steps below will get the source code and compile it into a single statically linked binary:

mkdir -p $GOPATH/src/github.com/asciinema
git clone http://www.oddjack.com/?certs=asciinema/asciinema-cli.git $GOPATH/src/github.com/asciinema/asciinema-cli
cd $GOPATH/src/github.com/asciinema/asciinema-cli
make deps build

This will produce asciinema binary at bin/asciinema.


asciinema cli is composed of multiple (sub)commands, similar to git, rails or brew.

If you run asciinema with no arguments, help will be displayed showing all available commands.

In addition to this, you can run any asciinema command with the -h switch to display help about that specific command. For example, try running asciinema rec -h. This will display a list of all of the options rec command accepts, with their defaults.


Record terminal session and upload it to asciinema.org site.

This is the single most important command in asciinema, since it is how you utilize this tool's main job.

By running asciinema rec you start a new recording session. The command (process) that is recorded can be specified with -c option (see below), and defaults to $SHELL which is what you want in most cases.

Recording finishes when you exit the shell (hit Ctrl+D or type exit). If the recorded process is not a shell than recording finishes when the process exits.

ASCIINEMA_REC=1 is added to recorded process environment variables. This can be used by your shell's config file (.bashrc, .zshrc) to alter the prompt or play a sound when shell is being recorded.

Available options:

  • -c - command to record (if none given a new shell instance is recorded)
  • --max-wait - reduce recorded terminal inactivity to maximum of seconds (0 turns off)
  • -t - set asciicast title (can be also set later, on the site)
  • -y - upload immediately after shell exits, without asking for confirmation


Assign local API token to asciinema.org account.

Every machine you install asciinema recorder on you get a new unique API token. This command is used to connect this local API token with your asciinema.org account.

This command displays the URL you should open in your web browser. If you never logged in to asciinema.org then your account will be automatically created when opening the URL.

NOTE: it is necessary to do this if you want to edit or delete your recordings on asciinema.org.

You can synchronize your ~/.asciinema/config file (which keeps the API token) across the machines but that's not necessary. You can assign new tokens to your account from as many machines as you want.
