Shell script to capture Process ID and kill it if exist
提问by user1597811
I tried this code and it is not working
我试过这段代码，但它不起作用
#!/bin/sh
#Find the Process ID for syncapp running instance
PID=`ps -ef | grep syncapp 'awk {print }'`
if [[ -z "$PID" ]] then
Kill -9 PID
fi
It is showing a error near awk.
它在 awk 附近显示错误。
Any suggestions please.
请提出任何建议。

Actually the easiest way to do that would be to pass kill arguments like below:
实际上，最简单的方法是传递如下的 kill 参数：
ps -ef | grep your_process_name | grep -v grep | awk '{print }' | xargs kill
Hope it helps.
希望能帮助到你。

This works good for me.
这对我很有用。
PID=`ps -eaf | grep syncapp | grep -v grep | awk '{print }'`
if [[ "" != "$PID" ]]; then
echo "killing $PID"
kill -9 $PID
fi

I use the command pkillfor this:
我pkill为此使用命令：
NAME
pgrep, pkill - look up or signal processes based on name and
other attributes
SYNOPSIS
pgrep [options] pattern
pkill [options] pattern
DESCRIPTION
pgrep looks through the currently running processes and lists
the process IDs which match the selection criteria to stdout.
All the criteria have to match. For example,
$ pgrep -u root sshd
will only list the processes called sshd AND owned by root.
On the other hand,
$ pgrep -u root,daemon
will list the processes owned by root OR daemon.
pkill will send the specified signal (by default SIGTERM)
to each process instead of listing them on stdout.
If your code runs via interpreter (java, python, ...) then the name of the process is the name of the interpreter. You need to user the argument --full. This matches against the command name and the arguments.
如果您的代码通过解释器（java、python、...）运行，那么进程的名称就是解释器的名称。您需要使用参数 --full。这与命令名称和参数匹配。

You probably wanted to write
你可能想写
`ps -ef | grep syncapp | awk '{print }'`
but I will endorse @PaulR's answer - killall -9 syncappis a much better alternative.
但我会赞同@PaulR 的回答——这killall -9 syncapp是一个更好的选择。

A lot of *NIX systems also have either or both pkill(1)and killall(1)which, allows you to kill processes by name. Using them, you can avoid the whole parsing psproblem.
许多 *NIX 系统也有pkill(1)和killall(1) 之一或两者，它们允许您按名称杀死进程。使用它们，您可以避免整个解析ps问题。

Came across somewhere..thought it is simple and useful

You can use the command in crontab directly ,
可以直接在 crontab 中使用该命令，
* * * * * ps -lf | grep "user" | perl -ane '($h,$m,$s) = split /:/,$F
+[13]; kill 9, $F[3] if ($h > 1);'
or, we can write it as shell script ,
或者，我们可以把它写成 shell script ，
#!/bin/sh
# longprockill.sh
ps -lf | grep "user" | perl -ane '($h,$m,$s) = split /:/,$F[13]; kill
+ 9, $F[3] if ($h > 1);'
And call it crontab like so,
并像这样称其为 crontab，
* * * * * longprockill.sh

#!/bin/sh
#Find the Process ID for syncapp running instance
PID=`ps -ef | grep syncapp 'awk {print }'`
if [[ -z "$PID" ]] then
---> Kill -9 PID
fi
Not sure if this helps, but 'kill' is not spelled correctly. It's capitalized.
不确定这是否有帮助，但“kill”拼写不正确。它是大写的。
Try 'kill' instead.
尝试“杀死”。
回答by EvR2f
This should kill all processes matching the grep that you are permitted to kill.
这应该会杀死与您被允许杀死的 grep 匹配的所有进程。
-9 means "Kill all processes you can kill".
-9 表示“杀死所有可以杀死的进程”。
kill -9 $(ps -ef | grep [s]yncapp | awk '{print }')
回答by Not_a_User
Kill -9 PID
should be
应该
kill -9 $PID
see the difference?
看到不同？

Try the following script:
尝试以下脚本：
#!/bin/bash
pgrep 2>&1 > /dev/null
if [ $? -eq 0 ]
then
{
echo " "" PROCESS RUNNING "
ps -ef | grep | grep -v grep | awk '{print }'| xargs kill -9
}
else
{
echo " NO PROCESS RUNNING"
};fi
