Getting PID of sshd

I开发者_运维百科 am executing sshd in a bash script using

$ /usr/sbin/sshd

How do I get the process ID of this sshd that I executed?

sshd will typically write a PID file; by default this is at /var/run/sshd.pid. You can use this to find the process ID of the listening sshd process. You should be aware that sshd may fork several subprocesses as it works, so what you want really depends on what you intend to do with it.

Try this command:

ps aux | grep -e /usr/sbin/sshd | grep -v grep | tr -s " " | cut -d " " -f2

or

cat /var/run/sshd.pid
