SunOS/BSD Compatibility Package Commandsrusage(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 seconds 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)

         icx 24 mx 0 ix 1230 id 9 is

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

real elapsed real time
userru_utimeuser time used
sysru_stimesystem time used
pfru_majfltpage faults requiring physical I/O
prru_minfltpage faults not requiring physical I/O
swru_nswapswaps
