[英]Running commands remotely returns unexpected output
I want to kill a process remotely and I use ssh -i
command like this: 我想远程杀死一个进程,并且使用
ssh -i
命令,如下所示:
ssh -i $app_rsa_file_path $app_server_user@$app_server_ip "ps aux | grep java | grep billing | awk '{print $2}' | xargs kill -9 > /dev/null 2>&1"
if I run command directly on the server, it works fine; 如果我直接在服务器上运行命令,它将正常工作; but in remote version it seems that
awk
has no effect and the command passes the whole output of ps aux | grep java | grep billing
但是在远程版本中,
awk
似乎没有任何作用,该命令将传递ps aux | grep java | grep billing
的整个输出。 ps aux | grep java | grep billing
ps aux | grep java | grep billing
to kill
and I get this: ps aux | grep java | grep billing
kill
,我得到这个:
kill: invalid option -- 'D'
Usage:
kill [options] <pid> [...]
Options:
<pid> [...] send signal to every <pid> listed
-<signal>, -s, --signal <signal>
specify the <signal> to be sent
-l, --list=[<signal>] list all signal names, or convert one to a name
-L, --table list all signal names in a nice table
-h, --help display this help and exit
-V, --version output version information and exit
For more details see kill(1).
Any idea about the reason? 知道原因吗?
