adb命令是adb这个程序自己的命令。adb shell是Android系统自带的命令，都保存在Android系统的/system/bin目录下，命令文件本质是shell脚本。

ADB命令

adb devices：获取当前所有已连接设备的list。
adb get-state：获取设备的状态。
设备的状态有三种：device、offline、unknow。

状态	意义
device	设备已连接
offline	设备脱机
unknow	设备状态不可知

adb kill-server：停止adb服务。
adb start-server：开启adb服务。
这两个状态通常配对使用。
adb logcat：输出Android系统日志。
adb bugrepot：打印dumpsys、dumpstate、logcat的输出，用于错误分析。
adb install：用于app安装，-r参数覆盖安装。
adb uninstall：用于app卸载。
adb pull：用于将Android系统中的文件或文件夹复制到本地。
adb push：用于将本地文件或文件夹复制到Android系统指定文件目录下。
这两个命令如果处理的是系统文件或文件夹需要先获取到root权限然后remount系统文件获取读写权限。
adb root、adb remount：用于获取root权限再重新挂载系统文件获取读写权限。
adb reboot：重启android系统。
adb forward：用于将宿主机上的某个端口重定向到Android机上的某个端口。例如：adb forward tcp:123 tcp:8888 这条命令就会把发往主机123端口的数据转发到Android机的8888端口，一般用于远程控制等。
adb connect：用于无线adb连接，要求宿主机和Android机在同一个局域网络下。例如：adb connect 192.168.1.100，这个ip地址就是手机在局域网中的ip。缺点是延迟大。
adb shell：可以执行Android系统命令。
下面介绍的都是adb shell命令。

am start -n com.android.camera/.Camera
先停止目标应用，再启动：
am start -S com.android.camera/.Camera
等待应用完成启动：
am start -W com.android.camera/.Camera
启动默认浏览器打开一个网页：
am start -a android.intent.action.VIEW -d http://www.baidu.com
启动拨号器拨打 10086：
am start -a android.intent.action.CALL -d tel:10086

am instrument , 启动一个 instrumentation , 单元测试或者 Robotium 会用到。

am monitor , 监控 crash 与 ANR。

am force-stop , 后跟包名，结束应用。

am startservice , 启动一个服务。

am broadcast , 发送一个广播。
后面的参数有：
[-a ]
[-d <DATA_URI>]
[-t <MIME_TYPE>]
[-c [-c ] …]
[-e|–es <EXTRA_KEY> <EXTRA_STRING_VALUE> …]
[–ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> …]
[-e|–ei <EXTRA_KEY> <EXTRA_INT_VALUE> …]
[-n ]
[-f ] []

input swipe 500 500 501 501 2000
其实就是在小的距离内，在较长的持续时间内进行滑动，最后表现出来的结果就是长按动作

screencap

截屏命令，格式：screencap [-hp] [-d display-id] [FILENAME]

yfve_8q:/ # screencap -h
usage: screencap [-hp] [-d display-id] [FILENAME]-h: this message-p: save the file as a png.-d: specify the display id to capture, default 0.
If FILENAME ends with .png it will be saved as a png.
If FILENAME is not given, the results will be printed to stdout.
yfve_8q:/ #

例

# 截0号屏，保存至 /sdcard/screencap0.png
screencap -p /sdcard/screencap0.png

screenrecord

4.4 新增的录制命令，格式：screenrecord [options] [filename]

yfve_8q:/ # screenrecord --h
Usage: screenrecord [options] <filename>Android screenrecord v1.2.  Records the device's display to a .mp4 file.Options:
--size WIDTHxHEIGHTSet the video size, e.g. "1280x720".  Default is the device's maindisplay resolution (if supported), 1280x720 if not.  For best results,use a size supported by the AVC encoder.
--bit-rate RATESet the video bit rate, in bits per second.  Value may be specified asbits or megabits, e.g. '4000000' is equivalent to '4M'.  Default 20Mbps.

1. 缓冲区简介
android log输出量巨大，特别是通信系统的log，因此，android把log输出到不同的缓冲区中，目前定义了四个log缓冲区：

Radio：输出通信系统的log
System：输出系统组件的log
Event：输出event模块的log
Main：所有java层的log，遗迹不属于上面3层的log

缓冲区主要给系统组件使用，一般的应用不需要关心，应用的log都输出到main缓冲区中。

默认log输出（不指定缓冲区的情况下）是输出System和Main缓冲区的log。

2. Logcat参数和过滤项
日志输出命令，格式：logcat [参数] [过滤项], 其中选项和过滤项在中括号 [] 中, 说明这是可选的。

参数	意义
-s	设置输出日志的标签, 只显示该标签的日志
-f [filename]	将日志输出到文件[filename]中，才用默认输出格式
-r [kbyte]	按照[kbyte]千字节输出日志，默认是16，需要和 -f 参数一起使用
-n [count]	设置日志输出的最大数目为[count]，默认是4，需要和-r 参数一起使用
-v [format]	设置日志的输出格式为[format]
-c	清空所有的日志缓存信息
-d	将缓存的日志输出到屏幕上, 并且不会阻塞
-t	输出最近的几行日志, 输出完退出, 不阻塞
-g	查看日志缓冲区信息
-b [buffer]	加载可以使用的一个日志缓冲区供查看，默认是 main
-B	以二进制形式输出日志

一般长时间输出log的话建议-f，-n，-r三个参数连用，这样当一个文件日志输出满了之后可以马上在另一个中进行输出。

3. 过滤格式
过滤项格式 : [:priority] , 标签:日志等级, 默认的日志过滤项是 " *:I " ;

过滤项	意义
V	Verbose (明细);
D	Debug (调试);
I	Info (信息);
W	Warn (警告);
E	Error (错误);
F	Fatal (严重错误);
S	Silent(Super all output) (最高的优先级, 可能不会记载东西);

-s参数
用来过滤日志文件的标签。如logcat -s System.out。
和grep命令相似，不过grep过滤标签和日志内容在内的所有内容，而-s只过滤标签。
-f参数
将日志输出到指定文件中。
和重定向符">"功能差不多。
-v参数
指定日志输出格式。logcat -v [格式]

格式	意义
time	日志格式：日期时间优先级 / 标签 (进程ID) : 进程名称 : 日志信息
threadtime	日志的输出时间和线程信息
prief	默认的日志格式：优先级 / 标签（进程ID）: 日志信息
progress	日志格式：优先级（进程ID） : 日志信息
tag	日志格式：优先级 / 标签 : 日志信息
thread	日志格式：优先级 ( 进程ID : 线程ID) 标签 : 日志内容
raw	只输出日志信息, 不附加任何其他信息, 如优先级标签等
long	日志格式：[ 日期时间进程ID : 线程ID 优先级 / 标签] 日志信息

grep

usage: grep [-abcDEFGHhIiJLlmnOoPqRSsUVvwxZz] [-A num] [-B num] [-C[num]][-e pattern] [-f file] [--binary-files=value] [--color=when][--context[=num]] [--directories=action] [--label] [--line-buffered][pattern] [file ...]
yfve_8q:/ #

grep是查找字符串命令。grep支持正则表达式。格式是：grep [参数] [pattern]

参数	意义
-a或–text	不要忽略二进制的数据。
-A<显示列数>或–after-context=<显示列数>	除了显示符合范本样式的那一列之外，并显示该列之后的内容。
-b或–byte-offset	在显示符合范本样式的那一列之前，标示出该列第一个字符的位编号。
-B<显示列数>或–before-context=<显示列数>	除了显示符合范本样式的那一列之外，并显示该列之前的内容。
-c或–count	计算符合范本样式的列数。
-C<显示列数>或–context=<显示列数>或-<显示列数>	除了显示符合范本样式的那一列之外，并显示该列之前后的内容。
-d<进行动作>或–directories=<进行动作>	当指定要查找的是目录而非文件时，必须使用这项参数，否则grep指令将回报信息并停止动作。
-e<范本样式>或–regexp=<范本样式>	指定字符串做为查找文件内容的范本样式。
-E或–extended-regexp	将范本样式为延伸的普通表示法来使用。
-f<范本文件>或–file=<范本文件>	指定范本文件，其内容含有一个或多个范本样式，让grep查找符合范本条件的文件内容，格式为每列一个范本样式。
-F或–fixed-regexp	将范本样式视为固定字符串的列表。
-G或–basic-regexp	将范本样式视为普通的表示法来使用。
-h或–no-filename	在显示符合范本样式的那一列之前，不标示该列所属的文件名称。
-H或–with-filename	在显示符合范本样式的那一列之前，表示该列所属的文件名称。
-i或–ignore-case	忽略字符大小写的差别。
-l或–file-with-matches	列出文件内容符合指定的范本样式的文件名称。
-L或–files-without-match	列出文件内容不符合指定的范本样式的文件名称。
-n或–line-number	在显示符合范本样式的那一列之前，标示出该列的列数编号。
-q或–quiet或–silent	不显示任何信息。
-r或–recursive	此参数的效果和指定"-d recurse"参数相同。
-s或–no-messages	不显示错误信息。
-v或–revert-match	反转查找。
-V或–version	显示版本信息。
-w或–word-regexp	只显示全字符合的列。
-x或–line-regexp	只显示全列符合的列。
