logcat のヘルプ

# logcat -h
unknown option -- hUnrecognized Option 
Usage: logcat [options] [filterspecs]
options include:
 -s              Set default filter to silent.
                 Like specifying filterspec '*:s'
 -f <filename>   Log to file. Default to stdout
 -r [<kbytes>]   Rotate log every kbytes. (16 if unspecified). Requires -f
 -n <count>      Sets max number of rotated logs to <count>, default 4
 -v <format>     Sets the log print format, where <format> is one of:

                 brief process tag thread raw time threadtime long

 -c              clear (flush) the entire log and exit
 -d              dump the log and then exit (don't block)
 -t <count>      print only the most recent <count> lines (implies -d)
 -g              get the size of the log's ring buffer and exit
 -b <buffer>     request alternate ring buffer
                 ('main' (default), 'radio', 'events')
 -B              output the log in binary filterspecs are a series of 

where <tag> is a log component tag (or * for all) and priority is:
 V    Verbose
 D    Debug
 I    Info
 W    Warn
 E    Error
 F    Fatal
 S    Silent (supress all output)

'*' means '*:d' and <tag> by itself means <tag>:v

If not specified on the commandline, filterspec is set from ANDROID_LOG_TAGS.
If no filterspec is found, filter defaults to '*:I'

If not specified with -v, format is set from ANDROID_PRINTF_LOG
or defaults to "brief"
