best find command

This is just one of the best find statements I have ever seen.

# find /sbin -xdev -type f -size +1024 -exec ll {} \; | awk '{print $9, $5}' | sort -rn +1 | awk '{print $1, $2/1024/1024 "MB"}' | more

For Linux

Hung Solaris Zone : shutting_down state

I had a zone stuck in shutting_down state.

No matter what I did I was not able to shut it down.

But this worked.

# ps -fz myzone
     UID   PID  PPID   C    STIME TTY         TIME CMD
    root  2850     1   0   Jul 22 ?           0:00 zsched
 0040620 18081     1   0        - ?        2529:10 defunct

The problem was that I had a process on the zone that was defunct.

After several kill -9 the defunct process finally died and my zones shutdown and rebooted.

NOTE: YOU SHOULD NOT KILL zsched.
