The command (process) that is recorded can be specified with \f[B]\-c\f[] option (see below), and defaults to \f[B]$SHELL\f[] which is what you want in most cases. .PP Recording finishes when you exit the shell (hit Ctrl+D or type \f[C]exit\f[]). If the recorded process is not a shell then recording finishes when the process exits. .PP If the \f[I]filename\f[] argument is omitted then (after asking for confirmation) the resulting asciicast is uploaded to asciinema\-server (https://github.com/asciinema/asciinema-server) (by default to asciinema.org), where it can be watched and shared. .PP If the \f[I]filename\f[] argument is given then the resulting recording (called asciicast (doc/asciicast-v2.md)) is saved to a local file. It can later be replayed with \f[B]asciinema play \f[] and/or uploaded to asciinema server with \f[B]asciinema upload \f[]. .PP \f[B]ASCIINEMA_REC=1\f[] is added to recorded process environment variables. This can be used by your shell's config file (\f[C]\&.bashrc\f[], \f[C]\&.zshrc\f[]) to alter the prompt or play a sound when the shell is being recorded. .TP .B Available options: \ .RS .TP .B \f[C]\-\-stdin\f[] Enable stdin (keyboard) recording (see below) .RS .RE .TP .B \f[C]\-\-append\f[] Append to existing recording .RS .RE .TP .B \f[C]\-\-raw\f[] Save raw STDOUT output, without timing information or other metadata .RS .RE .TP .B \f[C]\-\-overwrite\f[] Overwrite the recording if it already exists .RS .RE .TP .B \f[C]\-c,\ \-\-command=\f[] Specify command to record, defaults to \f[B]$SHELL\f[] .RS .RE .TP .B \f[C]\-e,\ \-\-env=\f[] List of environment variables to capture, defaults to \f[B]SHELL,TERM\f[] .RS .RE .TP .B \f[C]\-t,\ \-\-title=\f[] Specify the title of the asciicast .RS .RE .TP .B \f[C]\-i,\ \-\-idle\-time\-limit=<sec>\f[] Limit recorded terminal inactivity to max \f[C]<sec>\f[] seconds .RS .RE .TP .B \f[C]\-y,\ \-\-yes\f[] Answer \[lq]yes\[rq] to all prompts (e.g.\ upload confirmation) .RS .RE .TP .B \f[C]\-q,\ \-\-quiet\f[] Be quiet, suppress all notices/warnings (implies \f[B]\-y\f[]) .RS .RE .RE .PP Stdin recording allows for capturing of all characters typed in by the user in the currently recorded shell. This may be used by a player (e.g. asciinema\-player (https://github.com/asciinema/asciinema-player)) to display pressed keys. Because it's basically a key\-logging (scoped to a single shell instance), it's disabled by default, and has to be explicitly enabled via \f[B]\[en]stdin\f[] option. .SS play <\f[I]filename\f[]> .PP Replay recorded asciicast in a terminal. .PP This command replays given asciicast (as recorded by \f[B]rec\f[] command) directly in your terminal. .PP Following keyboard shortcuts are available: .IP .nf \f[C] Space\ \-\ toggle\ pause, \&.\ \-\ step\ through\ a\ recording\ a\ frame\ at\ a\ time\ (when\ paused), Ctrl+C\ \-\ exit. \f[] .fi .PP Playing from a local file: .IP .nf \f[C] asciinema\ play\ /path/to/asciicast.cast \f[] .fi .PP Playing from HTTP(S) URL: .IP .nf \f[C] asciinema\ play\ https://asciinema.org/a/22124.cast asciinema\ play\ http://example.com/demo.cast \f[] .fi .PP Playing from asciicast page URL (requires \f[C]<link\ rel="alternate"\ type="application/x\-asciicast"\ href="/my/ascii.cast">\f[] in page's HTML): .IP .nf \f[C] asciinema\ play\ https://asciinema.org/a/22124 asciinema\ play\ http://example.com/blog/post.html \f[] .fi .PP Playing from stdin: .IP .nf \f[C] cat\ /path/to/asciicast.cast\ |\ asciinema\ play\ \- ssh\ user\@host\ cat\ asciicast.cast\ |\ asciinema\ play\ \- \f[] .fi .PP Playing from IPFS: .IP .nf \f[C] asciinema\ play\ dweb:/ipfs/QmNe7FsYaHc9SaDEAEXbaagAzNw9cH7YbzN4xV7jV1MCzK/ascii.cast \f[] .fi .TP .B Available options: \ .RS .TP .B \f[C]\-i,\ \-\-idle\-time\-limit=<sec>\f[] Limit replayed terminal inactivity to max \f[C]<sec>\f[] seconds .RS .RE .TP .B \f[C]\-s,\ \-\-speed=<factor>\f[] Playback speed (can be fractional) .RS .RE .RE .SS cat <\f[I]filename\f[]> .PP Print full output of recorded asciicast to a terminal. .PP While \f[B]asciinema play \f[] replays the recorded session using timing information saved in the asciicast, \f[B]asciinema cat \f[] dumps the full output (including all escape sequences) to a terminal immediately. .PP \f[B]asciinema cat existing.cast >output.txt\f[] gives the same result as recording via \f[B]asciinema rec \-\-raw output.txt\f[]. .SS upload .PP Upload recorded asciicast to asciinema.org site. .PP This command uploads given asciicast (recorded by \f[B]rec\f[] command) to asciinema.org, where it can be watched and shared. .PP \f[B]asciinema rec demo.cast\f[] + \f[B]asciinema play demo.cast\f[] + \f[B]asciinema upload demo.cast\f[] is a nice combo if you want to review an asciicast before publishing it on asciinema.org. .SS auth .PP Link your install ID with your asciinema.org user account. .PP If you want to manage your recordings (change title/theme, delete) at asciinema.org you need to link your \[lq]install ID\[rq] with asciinema.org user account. .PP This command displays the URL to open in a web browser to do that. You may be asked to log in first. .PP Install ID is a random ID (UUID v4 (https://en.wikipedia.org/wiki/Universally_unique_identifier)) generated locally when you run asciinema for the first time, and saved at \f[B]$HOME/.config/asciinema/install\-id\f[]. It's purpose is to connect local machine with uploaded recordings, so they can later be associated with asciinema.org account. This way we decouple uploading from account creation, allowing them to happen in any order. .PP Note: A new install ID is generated on each machine and system user account you use asciinema on, so in order to keep all recordings under a single asciinema.org account you need to run \f[B]asciinema auth\f[] on all of those machines. .PP Note: asciinema versions prior to 2.0 confusingly referred to install ID as \[lq]API token\[rq]. .SH EXAMPLES .PP Record your first session: .IP .nf \f[C] asciinema\ rec\ first.cast \f[] .fi .PP Now replay it with double speed: .IP .nf \f[C] asciinema\ play\ \-s\ 2\ first.cast \f[] .fi .PP Or with normal speed but with idle time limited to 2 seconds: .IP .nf \f[C] asciinema\ play\ \-i\ 2\ first.cast \f[] .fi .PP You can pass \f[B]\-i 2\f[] to \f[B]asciinema rec\f[] as well, to set it permanently on a recording. Idle time limiting makes the recordings much more interesting to watch, try it. .PP If you want to watch and share it on the web, upload it: .IP .nf \f[C] asciinema\ upload\ first.cast \f[] .fi .PP The above uploads it to <https://asciinema.org>, which is a default asciinema\-server (<https://github.com/asciinema/asciinema-server>) instance, and prints a secret link you can use to watch your recording in a web browser. .PP You can record and upload in one step by omitting the filename: .IP .nf \f[C] asciinema\ rec \f[] .fi .PP You'll be asked to confirm the upload when the recording is done, so nothing is sent anywhere without your consent. .SH ENVIRONMENT .TP .B \f[B]ASCIINEMA_API_URL\f[] This variable allows overriding asciinema\-server URL (which defaults to https://asciinema.org) in case you're running your own asciinema\-server instance. .RS .RE .TP .B \f[B]ASCIINEMA_CONFIG_HOME\f[] This variable allows overriding config directory location. Default location is $XDG_CONFIG_HOME/asciinema (when $XDG_CONFIG_HOME is set) or $HOME/.config/asciinema. .RS .RE .SH BUGS .PP See GitHub Issues: <https://github.com/asciinema/asciinema/issues> .SH AUTHORS .PP asciinema's lead developer is Marcin Kulik. .PP For a list of all contributors look here: <https://github.com/asciinema/asciinema/contributors> .PP This Manual Page was written by Marcin Kulik with help from Kurt Pfeifle.
