Kill pid by found name in adb shell

Question

I am trying kill the process by pid but without success yet. To get pid I use command in adb shell:

echo $(ps |grep myword) | cut -d' ' -f2

To kill pid I use command:

kill <PID>

But I cannot join that two commands.. What I've tried was:

kill $($(ps |grep debug) | cut -d' ' -f2)

but it is somehow wrong. Could I ask you for a help?

tl;dr

The problem is about joining two commands in adb shell, android console -to kill process found by name.

echo $(ps |grep myword) | cut -d' ' -f2
kill <PID>

I forgot to say: I am working on Windows7, so grep might not working in console. Really sorry for this.

I also tried this command:

adb shell "su -c 'echo $(ps | grep process_name) | cut -d' ' -f2 | xargs kill'"

This example is working well, however last part xargs fails:

adb shell ^" "su -c 'echo $(ps | grep ror)'|cut -d' ' -f2"

if you have busybox installed use `busybox killall app_name` — Alex P., Aug 05 '14 at 16:32

The process can be killed the following ways (On Linux System).

With your approach, the command (on ADB shell) should be as follows:
echo $(ps | grep process_name) | cut -d' ' -f2 | xargs kill
On ADB shell
ps | grep process_name | awk '{print $2}' | xargs kill
On the host machine as
adb shell ps | grep process_name | awk '{print $2}' | xargs adb shell kill
You can use busybox and do it. You can also build your own command (ex. pkill), like shown here. killall is already supported by busybox.

Option one should resolve your query, I would prefer the second option.

numer 1 is cool however I need su, I don't want use busybox. What I need is to start command with `adb shell...` Numer 2 is okay but I am working on Win7 – deadfish Aug 06 '14 at 06:43
Looks like to me, to kill any process you would require `su` or `sudo` Which device are you working on ? I believe `busybox` would also require root! – Saurabh Meshram Aug 06 '14 at 06:57
Yes but I really don't want to use bb, okay `su` might be required – deadfish Aug 06 '14 at 06:57
Again, Which device are you working on ? – Saurabh Meshram Aug 06 '14 at 07:01
android, nexus 4, api > 4.4.4, I am calling commands from window's console – deadfish Aug 06 '14 at 07:10

The solution for command adb shell in windows7 was:

adb shell ^" "su -c 'ps | echo $(grep process_name) | cut -d " " -f2 |xargs kill '"

there is a problem with `cut -d " " -f2` part - it would return PID only when there was exactly 1 space between UID and PID, which is not always the case. – Alex P. Aug 13 '14 at 14:56
you are right, it is possible to use regexp – deadfish Aug 13 '14 at 17:00

Kill with single adb command:

adb shell "for pid in  \`ps  | grep process_name | sed 's/  */ /g' | \
     cut -d ' '  -f 2 \`; do kill \$pid; done"
