or:
dumpsys [-t TIMEOUT] [--priority LEVEL] [--help | -l | --skip SERVICES | SERVICE [ARGS]]
--help: shows this help
-l: only list services, do not dump them
-t TIMEOUT_SEC: TIMEOUT to use in seconds instead of default 10 seconds
-T TIMEOUT_MS: TIMEOUT to use in milliseconds instead of default 10 seconds
--proto: filter services that support dumping data in proto format. Dumps will be in proto format.

yfve_8q:/ #
yfve_8q:/ # logcat -h
Usage: logcat [options] [filterspecs]
options include:
-s Set default filter to silent. Equivalent to filterspec '*:S'
-f , --file= Log to file. Default is stdout
-r , --rotate-kbytes=
Rotate log every kbytes. Requires -f option
-n , --rotate-count=
Sets max number of rotated logs to , default 4
--id= If the signature id for logging to file changes, then clear
the fileset and continue
-v , --format=
Sets log print format verb and adverbs, where is:

-d Dump the log and then exit (don't block)
-e , --regex=

Quit after printing lines. This is meant to be
