eclipse 自帶的 LogCat 工具太垃圾了, 開始用 adb logcat 在終端查看日志;

1. 解析 adb logcat 的幫助信息
在命令行中輸入?adb logcat --help?命令, 就可以顯示該命令的幫助信息;
[plain]?view plaincopy

adb logcat 命令格式?: adb logcat [選項] [過濾項], 其中 選項 和 過濾項 在 中括號 [] 中, 說明這是可選的;
(1) 選項解析
選項解析?:?
--?"-s"選項?: 設(shè)置輸出日志的標簽, 只顯示該標簽的日志;
--"-f"選項?: 將日志輸出到文件, 默認輸出到標準輸出流中, -f 參數(shù)執(zhí)行不成功;
--"-r"選項?: 按照每千字節(jié)輸出日志, 需要 -f 參數(shù), 不過這個命令沒有執(zhí)行成功;
--"-n"選項?: 設(shè)置日志輸出的最大數(shù)目, 需要 -r 參數(shù), 這個執(zhí)行 感覺 跟 adb logcat 效果一樣;
--"-v"選項?: 設(shè)置日志的輸出格式, 注意只能設(shè)置一項;
--"-c"選項?: 清空所有的日志緩存信息;
--"-d"選項?: 將緩存的日志輸出到屏幕上, 并且不會阻塞;
--"-t"選項?: 輸出最近的幾行日志, 輸出完退出, 不阻塞;
--"-g"選項?: 查看日志緩沖區(qū)信息;
--"-b"選項?: 加載一個日志緩沖區(qū), 默認是 main, 下面詳解;
--"-B"選項?: 以二進制形式輸出日志;
.
輸出指定標簽內(nèi)容?:?
--?"-s"選項?: 設(shè)置默認的過濾器, 如 我們想要輸出 "System.out" 標簽的信息, 就可以使用adb logcat -s System.out?命令;
[plain]?view plaincopy
octopus@octopus:~$?adb?logcat?-s?System.out?? ---------?beginning?of?/dev/log/system?? ---------?beginning?of?/dev/log/main?? I/System.out(22930):?GSM?-91?? I/System.out(22930):?SignalStrength?issssssssss?:?-91?? I/System.out(22930):?GSM?-91?? I/System.out(22930):?SignalStrength?issssssssss?:?-91?? I/System.out(22930):?Supervisor?Thread?? I/System.out(22930):?Got?run?mode??
輸出日志信息到文件?:?
--?"-f"選項?: 該選向后面跟著輸入日志的文件, 使用adb logcat -f /sdcard/log.txt?命令, 注意這個log文件是輸出到手機上，需要指定合適的路徑。
[plain]?view plaincopy
octopus@octopus:~$?adb?logcat?-f /sdcard/log.txt???
這個參數(shù)對對不能一直用電腦連著手機收集日志的場景非常有用，其實android shell下也有一個相同參數(shù)的logcat命令。使用如下命令可以執(zhí)行后斷開PC和手機持續(xù)收集LOG。
[plain]?view plain
?copy shell@pc$?adb?shell?? shell@android$?logcat?-f?/sdcard/log.txt?&???#這里的&符號表示后臺執(zhí)行，別少了。?? shell@android$?exit??
注：
（1）以上shell@pc$ 指在pc的shell終端執(zhí)行后邊的命令， shell@android$ 表示在手機shell中執(zhí)行后邊的命令l
（2）一定注意合適的時候需要停止掉以上命令，否則再次使用相同命令的時候，就會有兩個logcat寫同一個文件了
????????? 停止方法:? adb shell kill -9 <logcat_pid>?????????
?????????? 其中l(wèi)ogcat_pid 通過 如下命令獲取
?????????? adb shell ps | grep logcat????????? # linux 平臺
?????????? adb shell ps | findstr "logcat" ?? #Windows平臺
--?">"輸出?: ">" 后面跟著要輸出的日志文件, 可以將 logcat 日志輸出到文件中, 使用adb logcat > log?命令, 使用more log?命令查看日志信息;
[plain]?view plaincopy
octopus@octopus:~$?adb?logcat?>?log?? ^C?? octopus@octopus:~$?more?log?? ---------?beginning?of?/dev/log/system?? V/ActivityManager(??500):?We?have?pending?thumbnails:?null??

--?" -d -f <log>" 組合命令：可以將日志保存到手機上的指定位置，對不能一直用電腦連著手機收集日志的場景非常有用。

(2) 過濾項解析
過濾項格式?:?<tag>[:priority] , 標簽:日志等級, 默認的日志過濾項是 " *:I " ;
--?V?: Verbose (明細);
--?D?: Debug (調(diào)試);
--?I?: Info (信息);
--?W?: Warn (警告);
--?E?: Error (錯誤);
--?F: Fatal (嚴重錯誤);
--?S?: Silent(Super all output) (最高的優(yōu)先級, 可能不會記載東西);
過濾指定等級日志?: 使用?adb logcat 10 *:E?命令, 顯示 Error 以上級別的日志;
[plain]?view plaincopy
octopus@octopus:~$?adb?logcat?*:E?? ?? Note:?log?switch?off,?only?log_main?and?log_events?will?have?logs!?? ---------?beginning?of?/dev/log/main??

過濾指定標簽等級日志?: 使用?adb logcat WifiHW:D *:S?命令進行過濾;
--?命令含義?: 輸出10條日志, 日志是 標簽為?WifiHW, 并且優(yōu)先級 Debug(調(diào)試) 等級以上的級別的日志;
--注意 *:S?: 如果沒有 *S 就會輸出錯誤;
[plain]?view plaincopy

E/WifiHW??(??441):?wifi_send_command?:?SCAN_RESULTS?;?interface?index=0;??
可以同時設(shè)置多個過濾器?: 使用adb logcat WifiHW:D dalvikvm:I *:S?命令,?輸出?WifiHW 標簽 的 Debug 以上級別 和?dalvikvm 標簽的 Info 以上級別的日志;
[plain]?view plaincopy

2. 使用管道過濾日志
(1) 過濾固定字符串
過濾固定字符串?: 只要命令行出現(xiàn)的日志都可以過濾, 不管是不是標簽;
--?命令?:?adb logcat | grep Wifi?;
[plain]?view plaincopy
octopus@octopus:~$?adb?logcat?|?grep?Wifi?? E/WifiHW??(??441):?wifi_send_command?:?AP_SCAN?1?;?interface?index=0;?? E/WifiHW??(??441):?wifi_send_command?:?SCAN_RESULTS?;?interface?index=0;?? E/WifiHW??(??441):?wifi_send_command?:?SCAN?;?interface?index=0;?? E/WifiHW??(??441):?wifi_send_command?:?AP_SCAN?1?;?interface?index=0;?? E/WifiHW??(??441):?wifi_send_command?:?SCAN_RESULTS?;?interface?index=0;?? E/WifiHW??(??441):?wifi_send_command?:?AP_SCAN?1?;?interface?index=0;?? E/WifiHW??(??441):?wifi_send_command?:?SCAN_RESULTS?;?interface?index=0;??
過濾字符串忽略大小寫?:?adb logcat | grep -i wifi?;
(2) 使用正則表達式匹配
分析日志?: 該日志開頭兩個字符是 "V/", 后面開始就是標簽, 寫一個正則表達式 "^..ActivityManager", 就可以匹配日志中的 "V/ActivityManager" 字符串;
[plain]?view plaincopy
V/ActivityManager(??574):?getTasks:?max=1,?flags=0,?receiver=null??
正則表達式過濾日志: 使用上面的正則表達式組成命令?adb logcat | grep "^..Activity"?;
