in reply to Finding out Processor Usage

It seems like there should be a CPAN module to do this, but I just searched for one and nothing useful came up.

top -b -n 1 -p 1 should be pretty easy to parse. Or vmstat, which displays how busy a CPU is. uptime is also available on all Unix systems I'm aware of, but the information it gives is somewhat limited.

    I agree, one would think there would be something on CPAN, but I must have looked for about 2 hours today and found nothing (except GTop).

    My version of top does not seem to support those options. By any chance do you know what they stand for, maybe if i knew that i could discern the equivalents on my system (Mac OS 10.3.3). Thanks.

      From my manpage: 
      COMMAND-LINE OPTIONS
...
       b    Batch mode. Useful for sending  output  from  top  to
            other  programs or to a file.  In this mode, top will
            not accept command line input. It runs until it  pro­
            duces  the  number of iterations requested with the n
            option or until killed. Output is plain text suitable
            for display on a dumb terminal.
...
       n    Number  of iterations. Update the display this number
            of times and then exit.
...
       p    Monitor  only  processes with given process id.  This
            flag can be given up to twenty times. This option  is
            neither  available  interactively  nor  can it be put
            into the configuration file.
