CVUSAGE(1)							    CVUSAGE(1)

NAME    [Toc]    [Back]

     cvusage - run a command, and print	out the	resources it used

SYNOPSIS    [Toc]    [Back]

     cvusage command [args]

DESCRIPTION    [Toc]    [Back]

     cvusage is	a WorkShop component that runs a process from the given
     command and arguments and prints out a summary of the resources used
     during the	run.  It is used in exactly the	same way as time(1), but
     prints additional information.

     The usage information is printed to stderr	in the form:
      1.89 real, 0.04 user, 0.29 sys, 15 majf, 2 minf, 0 sw, 1 rb, 0 wb, 21 vcx, 38 icx

     The real, user and	sys fields give	the real-time, user-CPU	time and
     system-CPU	time, respectively.

     majf gives	major page faults, those causing physical I/O.

     minf gives	minor page faults, those requiring mapping only.

     sw	gives process swaps.

     rb	and wb give physical blocks read and written, respectively.  Note that
     these are attributed to the process which first requests a	block, but do
     not necessarily directly correlate	with the process' own I/O operations.

     vcx gives voluntary context switches, that	is, those caused by the
     process' own actions.

     icx gives involuntary context switches, those caused by the scheduler.

     In	addition, if the command terminates abnormally,	a message to that
     effect is printed before the usage	line.
