CVUSAGE(1)                                                          CVUSAGE(1)



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

SYNOPSIS
     cvusage command [args]

DESCRIPTION
     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.
