file descriptor count
I am trying to write a script which will only show me the file descriptor count for a process/pid. My script will return me the count only not the whole output. For example, I would like my script to return the output 23 this case, not the whole output.
Can anybody please help me how do I get the last count only?
Thanks in advance who replies.

BUGS
The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
two instances. The method used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
systems.
