请问怎样远程获取某一台主机的某进程PID呢？

例如查询某进程的pid命令如下
ps -ef | grep libvirtd | grep -w '/usr/sbin/libvirtd' | grep -v 'grep' | awk '{print $2}'
- f9 R; X" ~; M0 _4 [7 j
7 s2 I% z# `) i8 i/ V! m/ s现在需要登录一台主机后台去获取另外一台主机的该进程的id，发现输出如下，返回不了想要的pid
. ~$ [) W1 n; J, Y. [% }2 xssh $ip "ps -ef | grep libvirtd | grep -w '/usr/sbin/libvirtd' | grep -v 'grep' | awk '{print $2}'"
' Q6 n" _$ x. v9 BAuthorized users only. All activity may be monitored and reported

ssh $ip "ps -ef | grep libvirtd | grep -w '/usr/sbin/libvirtd' | grep -v 'grep' | awk '{print \$2}'" 多加一个斜杠试试
