RUSAGE(1B) BSD Compatibility Package Commands RUSAGE(1B)
NAME
rusage - print resource usage for a command
SYNOPSIS
/usr/ucb/rusage commandDESCRIPTION
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.
