adb: Find PID from the adb shell
提问by rumit patel
I am trying to get the PID of the process INSIDE adb shell. So, I am doing adb shell which gets me to the android shell. Now, if I were to get the PID using a regular shell I would use
我正在尝试获取 INSIDE adb shell 进程的 PID。所以，我正在做 adb shell，它让我进入 android shell。现在，如果我要使用常规外壳获取 PID，我会使用
adb shell ps | grep android.process.acore | sed 's/\s\s*/ /g' | cut -d ' ' -f 2
OR
或者
adb shell ps | grep android.process.acore | awk '{ print }'
I get the PID (a numeric number - 2nd field of the ps | grep android.process.acore) output.
我得到了 PID（一个数字 - 的第二个字段ps | grep android.process.acore）输出。
However, if I run the above commands inside android shell(after doing adb shell), I get /system/bin/sh: sed: not foundand /system/bin/sh: awk: not founderrors respectively. Which means, these commands are not available inside adb shell. However, grep works.
但是，如果我在 android shell 中运行上述命令（在执行之后adb shell），我会分别得到/system/bin/sh: sed: not found和/system/bin/sh: awk: not found错误。这意味着，这些命令在 adb shell 中不可用。但是，grep 有效。
The output of the ps | grep android.process.acoreinside adb shellis:
ps | grep android.process.acore里面的输出adb shell是：
XXX_x21 11826 441 502296 39028 ffffffff 4010ff6c S android.process.acore
I am looking for the number 11826.
How can I extract it inside adb shell?
我正在寻找数字 11826。我怎样才能在里面提取它adb shell？
Also, please help if there is a direct way to get the PID inside the adb shell.
另外，如果有直接的方法可以在 adb shell 中获取 PID，请提供帮助。

Not sure if you can get the PID directly however you can try the following
不确定您是否可以直接获取 PID，但是您可以尝试以下操作
set `ps |grep android.process.acore` echo
This has the affect of setting the output of the ps command into variables $1, $2, $3 etc. The PID value is in $2
这会影响将 ps 命令的输出设置为变量 $1、$2、$3 等。PID 值在 $2 中

I tried this one and it seems to work:
我试过这个，它似乎有效：

-o omit PID(s)
