Android开发使用adblogcat显示Android日志

Android开发使用adblogcat显示Android日记Android开发使用adblogcat显示Android日记1.分析adblogcat的帮助信息在命令行中输入adblogcat--help命令,就可以显示该命令的帮助信息;[plain]viewplaincopyoctopus@octopus:~$adblogcat--helpUsage:logcat[options][filterspecs]optionsinclude:-sSetdefaultfiltertosilent.Likespecifyingfilterspec'*:s'-f<filename>Logtofile.Defaulttostdout-r[<kbytes>]Rotatelogeverykbytes.(16ifunspecified).Requires-f-n<count>Setsmaxnumberofrotatedlogsto<count>,default4-v<format>Setsthelogprintformat,where<format>isoneof:briefprocesstagthreadrawtimethreadtimelong-cclear(flush)theentirelogandexit-ddumpthelogandthenexit(don'tblock)-t<count>printonlythemostrecent<count>lines(implies-d)-ggetthesizeofthelog'sringbufferandexit-b<buffer>Requestalternateringbuffer,'main','system','radio'or'events'.Multiple-bparametersareallowedandtheresultsareinterleaved.Thedefaultis-bmain-bsystem.-Boutputtheloginbinaryfilterspecsareaseriesof<tag>[:priority]where<tag>isalogcomponenttag(or*forall)andpriorityis:VerboseDDebugIInfoWWarnErrorFatalSSilent(supressalloutput)'*'means'*:d'and<tag>byitselfmeans<tag>:vIfnotspecifiedonthecommandline,filterspecissetfromANDROID_LOG_TAGS.Ifnofilterspecisfound,filterdefaultsto'*:I'Ifnotspecifiedwith-v,formatissetfromANDROID_PRINTF_LOGordefaultsto"brief"adblogcat和过滤项

命令格式:adblogcat[选项][过滤项],在中括号[]中,说明这是可选的;(1)

此中选项选项分析选项分析

:--"-s"选项:设置输出日记的标签,只显示该标签的日记;--"-f"选项:将日记输出到文件,默认输出到标准输出流中,-f参数执行不行功;"-r"选项:依据每千字节输出日记,需要-f参数,但是这个命令没有执行成功;"-n"选项:设置日记输出的最大数量,需要-r参数,这个执行感觉跟adblogcat成效相同;"-v"选项:设置日记的输出格式,注意只好设置一项;"-c"选项:清空全部的日记缓存信息;"-d"选项:将缓存的日记输出到屏幕上,而且不会堵塞;"-t"选项:输出近来的几行日记,输出完退出,不堵塞;"-g"选项:查察日记缓冲区信息;"-b"选项:加载一个日记缓冲区,默认是main,下边详解;"-B"选项:以二进制形式输出日记;.输出指定标签内容:"-s"选项:设置默认的过滤器,如我们想要输出"System.out"标签的信息,就可以使用adblogcat-sSystem.out命令;[plain]viewplaincopyoctopus@octopus:~$adblogcat-sSystem.out---------beginningof/dev/log/system---------beginningof/dev/log/mainI/System.out(22930):GSM-91I/System.out(22930):SignalStrengthissssssssss:-91I/System.out(22930):GSM-91I/System.out(22930):SignalStrengthissssssssss:-91I/System.out(22930):SupervisorThreadI/System.out(22930):Gotrunmode输出日记信息到文件

:--"-f"选项:该选向后边跟着输入日记的文件,使用adblogcat-flog命令,会出现错误,这里我们不介绍使用该选项;[plain]viewplaincopyoctopus@octopus:~$adblogcat-flogcouldn'topenoutputfile:Read-onlyfilesystem
