Android過濾具體應用日誌的指令碼

最近新修改完善了一個指令碼，貼出來和大家分享一下。

功能：按照程式（包名）過濾某一程式的日誌，便於更加準確定位問題。

原理：根據報名找到進程ID，然後根據得到的進程ID過濾

代碼：

#!/usr/bin/env python#coding:utf-8#author:andrewallanwallace@gmail.com#This script is aimed to grep logs by application(User should input a packageName and then we look up for the process ids then separate logs by process ids).import osimport syspackageName=str(sys.argv[1])command = "adb shell ps | grep %s | awk '{print $2}'"%(packageName)p = os.popen(command)##for some applications,there are multiple processes,so we should get all the process idpid = p.readline().strip()filters = pidwhile(pid != ""):pid = p.readline().strip()if (pid != ''):filters = filters +  "|" + pid#print 'command = %s;filters=%s'%(command, filters)if (filters != '') :cmd = 'adb logcat | grep --color=always -E "%s" '%(filters)os.system(cmd)

假設上述指令碼儲存成logcatPkg.py 使用方法:

androidyue~/py_works (master)$ logcatPkg.py com.android.phone

結果：

注意：由於是根據pid過濾，所以可能會過濾出一些數字相關的無相關資訊。
