can't compress input from stdin?

[BlackMage2]

How i can compress input from stdin and output the bzip3 compressed content to stdout? (to forward them in bash for example to another program?

Please check the man page or the help screen; the behaviour is otherwise identical to this of bzip2:

% bzip3 --help | grep stdout
  -c, --stdout      force writing to standard output

Example:

% cat /usr/share/dict/words | tr a-z A-Z | bzip3 -cv | ent
    985084 -> 320319 bytes, 32.52%, 2.60 bpb
Entropy = 7.999407 bits per byte.

Optimum compression would reduce the size
of this 320319 byte file by 0 percent.

Chi square distribution for 320319 samples is 263.54, and randomly
would exceed this value 34.33 percent of the times.

Arithmetic mean value of data bytes is 127.6606 (127.5 = random).
Monte Carlo value for Pi is 3.143370921 (error 0.06 percent).
Serial correlation coefficient is 0.000315 (totally uncorrelated = 0.0).
