kill remote process by ssh [closed]

Question

I can't directly access target host, need ssh as a proxy.

How can I kill a process from local use ssh ? I try this:

ssh root@$center "ssh root@$ip \"ps -ef|grep -v grep|grep $target_dir/$main|awk '{print \$2}'|xargs kill\""

it got error:

kill: can't find process "root"

And how to avoid error where process not exist ?

Answer 1

Suppose your process' name is name, then you can try something like this:

ssh hostname "pid=\$(ps aux | grep 'name' | awk '{print \$2}' | head -1); echo \$pid |xargs kill"

Answer 2

Use pkill -f to easily kill a process by matching its command-line.

ssh root@$center ssh root@$ip pkill -f "$target_dir/$main"
