asciinema: terminal session recorder
NAMEasciinema - terminal session recorder
SYNOPSISasciinema [-h] [--version] command [<args>]
DESCRIPTIONTerminal session recorder and the best companion of asciinema.org service.
asciinema is composed of multiple commands, similar to git, apt-get or brew.
- -h, --help
- Display help message
- Display version information
Record terminal session.
This is the single most important command in asciinema, since it is how you utilize this tool's main job.
By running asciinema rec [filename] 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.
If the filename argument is given then the resulting recording is saved to a local file. It can later be replayed with asciinema play <filename> and/or uploaded to asciinema.org with asciinema upload <filename>. If the filename argument is omitted then (after asking for confirmation) the resulting asciicast is uploaded to asciinema.org for further playback in a web browser.
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
- specify command to record, defaults to $SHELL
- specify the title of the asciicast
- -w, --max-wait
- reduce recorded terminal inactivity to max <sec> seconds
- -y, --yes
- answer "yes" to all prompts (e.g. upload confirmation)
- -q, --quiet
- be quiet, suppress all notices/warnings (implies -y)
Replay recorded asciicast in a terminal.
This command replays given asciicast (as recorded by rec command) directly in your terminal.
When "-" is passed as a filename the asciicast is read from stdin.
NOTE: it is recommended to run it in a terminal of dimensions not smaller than the one used for recording as there's no "transcoding" of control sequences for new terminal size.
- Available options:
- -w, --max-wait
- reduce replayed terminal inactivity to max sec seconds
Upload recorded asciicast to asciinema.org site.
This command uploads given asciicast (as recorded by rec command) to asciinema.org for further playback in a web browser.
asciinema rec demo.json + asciinema play demo.json + asciinema upload demo.json is a nice combo for when you want to review an asciicast before publishing it on asciinema.org.
Assign local API token to asciinema.org account.
On every machine you install asciinema recorder, you get a new, unique API token. This command connects this local token with your asciinema.org account, and links all asciicasts recorded on this machine with the 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 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 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.

BUGSAll your bug reports and feature ideas are highly appreciated as they help to improve the quality and functionality of asciinema for everyone.
As the service is built of several parts there are separate bug trackers:
- issues and ideas for the command line recorder
- issues and ideas for the website
