runon

Somebody came to me with this interesting problem of running a process on a specific CPU under a multi-processor environment.(We use Tru64 Unix at office). This is when I came across this tool

runon(1)

runon - Runs a command or process on a specific CPU, a processor set
(pset), or a Resource Affinity Domain (RAD)

LSOF

LSOF(1)

Got to know about this UNIX tool which shows list of open files. A file can be ``a regular file, a directory, a block special file, a character special file, an executing text reference, a library, a stream or a network file" (from man lsof(1)).

Found this very useful when one wants to see list of TCP connection attached to any server.

Contains lots of command line options.
