Hi Dennis,

I think the average_PCPU for the date 20091116 at hours 08 should be 22.1818


Quote:
grep "20091116 08" filename | awk '{sum+=$11} END { print sum/NR}'

sum(1B) 					     SunOS/BSD Compatibility Package Commands						   sum(1B)

NAME
sum - calculate a checksum for a file SYNOPSIS
/usr/ucb/sum file... DESCRIPTION
sum calculates and displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an algorithm which may yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has been transferred between machines with different-sized ints. USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
sum(1), wc(1), attributes(5), largefile(5) DIAGNOSTICS
Read error is indistinguishable from EOF on most devices; check the block count. NOTES
sum and /usr/bin/sum (see sum(1)) return different checksums. This utility is obsolete. SunOS 5.10 8 Nov 1995 sum(1B)
