termrec − a tty recorder
termrec [−f format] [−e command] [outfile]
Termrec is a tty recorder; it can record the output of any text mode program which you can then replay with termplay, ttyplay, ipbt, ttyplayer, nh-recorder, asciinema or similar.
If outfile ends in .gz, .xz, .bz2 or .zst, the data will be appropriately compressed.
If no outfile is given, termrec will produce a name like 2008−11−27.13−02−42.ttyrec.bz2
You can write directly to some remote URLs, such as tcp://host:port but that’s usually of little use.
−f format, −−format
You can specify a format other
than ttyrec. Those available are:
ansi
No timing data. This is same as the output of script(1).
ttyrec
Compatible with ttyrec by Satoru Takabayashi.
nh-recorder
Compatible with nh-recorder by Helge Dennhardt.
asciicast
Compatible with asciinema by Marcin Kulik; format v2.
asciicast−v1
Likewise, format v1.
−e command, −−exec
Runs a command instead of spawning a shell and records its output.
−r, −−raw
Inhibits noting info about your terminal size and UTFness. This data is usually a good thing, but can confuse some programs. Also note that none of the formats provides a way to mark which exactly charset you use −− only if it’s UTF−8 or one of ancient ones.
−a, −−append
If the output file exists, it will be appended instead being overwritten.
−h, −−help
Shows a short explanation of parameters.
SHELL
Unless −e is given, this will be the shell spawned, falling back to /bin/sh if not set. On Windows, COMSPEC is used instead.
termplay(1), termtime(1), termcat(1).
