rusage

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

NAME

       rusage - print resource usage for a command

SYNOPSIS

       /usr/ucb/rusage command

DESCRIPTION

       The  rusage command is similar to time(1). It runs the given command, which must be specified; that is, command is not optional as it is in
       the C shell's timing facility. When the command is complete, rusage displays the real (wall clock), the system CPU, and the user CPU  times
       which  elapsed during execution of the command, plus other fields in the rusage structure, all on one long line. Times are reported in sec-
       onds and hundredths of a second.

EXAMPLES

       Example 1 The format of rusage output

       The example below shows the format of rusage output.

	 example% rusage wc /usr/share/man/man1/csh(1)
	 3045	13423	78071 /usr/share/man/man1/csh(1)
	 2.26 real 0.80 user 0.36 sys 11 pf 38 pr 0 sw 11 rb 0 wb 16 vcx 37
		  icx 24 mx 0 ix 1230 id 9 is
	 example%

       Each of the fields identified corresponds to an element of the rusage structure, as described in getrusage(3C), as follows:

       real			  elapsed real time
       user	 ru_utime	  user time used
       sys	 ru_stime	  system time used
       pf	 ru_majflt	  page faults requiring physical I/O
       pr	 ru_minflt	  page faults not requiring physical I/O
       sw	 ru_nswap	  swaps
       rb	 ru_inblock	  block input operations
       wb	 ru_oublock	  block output operations
       vcx	 ru_nvcsw	  voluntary context switches
       icx	 ru_nivcsw	  involuntary context switches
       mx	 ru_maxrss	  maximum resident set size
       ix	 ru_ixrss	  currently 0
       id	 ru_idrss	  integral resident set size
       is	 ru_isrss	  currently 0
