电脑系统ubuntu 16.04.4 LTS
1.发送指令apt-get install android-tools-adb安装adb,连接设备运行脚本,出现如下错误提示如下,看起来ADB的am指令错误。
2.卸载android-tools-adb,再发送指令apt-get install adb安装adb,运行脚本就很正常。
所以这两个指令有什么区别?求指导,感谢!

am start: start an Activity. Options are:
-D: enable debugging
-W: wait for launch to complete
--start-profiler <FILE>: start profiler and send results to <FILE>
-P <FILE>: like above, but profiling stops when app goes idle
-R: repeat the activity launch <COUNT> times. Prior to each repeat,
the top activity will be finished.
-S: force stop the target app before starting the activity
--opengl-trace: enable tracing of OpenGL functions
--user <USER_ID> | current: Specify which user to run as; if not
specified then run as the current user.
am startservice: start a Service. Options are:
--user <USER_ID> | current: Specify which user to run as; if not
specified then run as the current user.
am stopservice: stop a Service. Options are:
--user <USER_ID> | current: Specify which user to run as; if not
specified then run as the current user.
am force-stop: force stop everything associated with <PACKAGE>.
--user <USER_ID> | all | current: Specify user to force stop;
all users if not specified.
am kill: Kill all processes associated with <PACKAGE>. Only kills.
processes that are safe to kill -- that is, will not impact the user
experience.
--user <USER_ID> | all | current: Specify user whose processes to kill;
all users if not specified.
am kill-all: Kill all background processes.
am broadcast: send a broadcast Intent. Options are:
--user <USER_ID> | all | current: Specify which user to send to; if not
specified then send to all users.
--receiver-permission <PERMISSION>: Require receiver to hold permission.
am instrument: start an Instrumentation. Typically this target <COMPONENT>
is the form <TEST_PACKAGE>/<RUNNER_CLASS>. Options are:
-r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT). Use with
[-e perf true] to generate raw output for performance measurements.
-e <NAME> <VALUE>: set argument <NAME> to <VALUE>. For test runners a
common form is [-e <testrunner_flag> <value>[,<value>...]].
-p <FILE>: write profiling data to <FILE>
-w: wait for instrumentation to finish before returning. Required for
test runners.
--user <USER_ID> | current: Specify user instrumentation runs in;
current user if not specified.
--no-window-animation: turn off window animations while running.
am profile: start and stop profiler on a process. The given <PROCESS> argument
may be either a process name or pid. Options are:
--user <USER_ID> | current: When supplying a process name,
specify user of process to profile; uses current user if not specified.
am dumpheap: dump the heap of a process. The given <PROCESS> argument may
be either a process name or pid. Options are:
-n: dump native heap instead of managed heap
--user <USER_ID> | current: When supplying a process name,
specify user of process to dump; uses current user if not specified.
am set-debug-app: set application <PACKAGE> to debug. Options are:
-w: wait for debugger when application starts
--persistent: retain this value
am clear-debug-app: clear the previously set-debug-app.

when done to select where it should be delivered.
am monitor: start monitoring for crashes or ANRs.
--gdb: start gdbserv on the given port at crash/ANR
am hang: hang the system.
--allow-restart: allow watchdog to perform normal system restart
am restart: restart the user-space system.

am to-uri: print the given Intent specification as a URI.
am to-intent-uri: print the given Intent specification as an intent: URI.
am switch-user: switch to put USER_ID in the foreground, starting
execution of that user if it is currently stopped.
am stop-user: stop execution of USER_ID, not allowing it to run any
code until a later explicit switch to it.
am stack create: create a new stack relative to an existing one.
<TASK_ID>: the task to populate the new stack with. Must exist.
<RELATIVE_STACK_BOX_ID>: existing stack box's id.
<POSITION>: 0: before <RELATIVE_STACK_BOX_ID>, per RTL/LTR configuration,
1: after <RELATIVE_STACK_BOX_ID>, per RTL/LTR configuration,
2: to left of <RELATIVE_STACK_BOX_ID>,
3: to right of <RELATIVE_STACK_BOX_ID>, 4: above <RELATIVE_STACK_BOX_ID>, 5: below <RELATIVE_STACK_BOX_ID>
<WEIGHT>: float between 0.2 and 0.8 inclusive.
am stack movetask: move <TASK_ID> from its current stack to the top (true) or bottom (false) of <STACK_ID>.
am stack resize: change <STACK_ID> relative size to new <WEIGHT>.
am stack boxes: list the hierarchy of stack boxes and their contents.
am stack box: list the hierarchy of stack boxes rooted at <STACK_BOX_ID>.
