gong

GONG(1) 						      General Commands Manual							   GONG(1)

NAME

       gong - evaluate process performance

SYNOPSIS

       gong [-f] [-a] process-id

DESCRIPTION

       Gong is used to evaluate the performance of a process that is in execution.

       The  process-id	is  the process number of the process whose performance is to be evaluated.  The evaluation is performed by a set of three
       ``panelist'' routines, each of which analyzes one aspect (time, space, and tonality) of the performance of the process.	If  any  of  these
       routines is not amused by the performance, the process being analyzed is sent the gong(2) signal.  In addition, the process-id of the eval-
       uated process is written on the standard gong, for possible future corrective action.  (It is suggested that the standard gong be an  audi-
       ble alarm for proper effect.)  It is expected that after being gong(2)ed, the process will promptly commit suicide.

       The  -f	keyletter  argument  indicates	that  gong  is	to  invoke flog(1) with the unmerciful argument if the process does not respond to
       gong(2)ing.  In the absence of this argument, the process is continuously gong(2)ed, which may lead to the process becoming a deaf zombie.

       The -a keyletter argument indicates that if all three of the panelist routines gong(2)  a  process,  the  process  should  be  unmercifully
       flog(1)ged whether or not the -f keyletter is supplied.

FILES

       /dev/ding.dong is the standard gong.

SEE ALSO

       On  the	Applicability  of  Gonging to the Performance and Merit Review Process, Journal of Irreproducible Results, vol. 263, issue 19, pp.
       253-307.

BUGS

       If the named process does not exist, it is possible that gong will attempt an evaluation of itself, which may lead to a condition known	as
       compounded double ringing (see echo(1)).  Therefore, it is recommended that gong be used with extreme care.
