(see also `-H`) (default: 10101010)

-H, --rate-hz=<hz>                 Trace `hz` times per second

(see also `-s`) (default: 99)

(default: auto;

supported: 70 71 72 73 74 80)

-l, --limit=<num>                  Limit total number of traces to capture

(approximate limit in pgrep mode)

(default: 0; 0=unlimited)

-i, --time-limit-ms=<ms>           Stop tracing after `ms` milliseconds

-b, --buffer-size=<size>           Set output buffer size to `size`.

Note: In `-P` mode, setting this

above PIPE_BUF (4096) may lead to

interlaced writes across threads.

-f, --filter=<regex>               Filter output by POSIX regex

(default: none)

-F, --filter-negate=<regex>        Same as `-f` except negated

capital=negation)

(default: PT; none)

-c, --continue-on-error            Attempt to continue tracing after

encountering an error

-#, --comment=<any>                Ignored; intended for self-documenting

commands

-@, --nothing                      Ignored
