The following command produced the unix domain socket opened by PID 30661
$ sudo lsof -U -a -p 30661
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
haproxy 30661 haproxy 7u unix 0xc784a000 0t0 3348210055 /var/lib/haproxy/stats.30660.tmp
I want a command using lsof internal options to give the output as just "var/lib/haproxy/stats.30660.tmp"
I don't want to use pipe and other tools to get this output.
