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.
Options:-fformat, --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.
-ecommand, --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.
