NAME

       hatimerun - run child program under a timeout

SYNOPSIS

       /usr/cluster/bin/hatimerun -t timeOutSecs [-av] [-e exitcode]
       prog args

       /usr/cluster/bin/hatimerun -t timeOutSecs [-v] [-e exitcode]
       [-k signalname] prog args

DESCRIPTION

       The  hatimerun utility provides a convenient facility for timing out the execution of another child, program. It is useful when programming
       in scripting languages, such as the Bourne shell. See sh(1).

       The hatimerun utility runs the program prog with arguments args as a child subprocess under a timeout, and as its own  process  group.  The
       timeout is specified in seconds, by the -t timeOutSecs option.  If the timeout expires, then hatimerun kills the child subprocess's process
       group with a SIGKILL signal, and then exits with exit code 99.

       You can run this command in the global zone or in a non-global zone. The command affects only the global or non-global zone  in	which  you
       issue the command.

OPTIONS

       The following options are supported:

       -a	    Changes  the meaning of hatimerun radically: instead of killing the child when the timeout expires, the hatimerun utility sim-
		    ply exits, with exit code 99, leaving the child to run asynchronously.

		    It is illegal to supply both the -a option and the -k option.

       -e	    Changes the exit code for the timeout case to some other value than 99.

       -k	    Specifies what signal is used to kill the child process group. The possible signal names are the same as those  recognized	by
		    the  kill(1)  command.   In particular, the signal name should be one of the symbolic names defined in the <signal.h> descrip-
		    tion. The signal name is recognized in a case-independent fashion, without the SIG prefix.	It  is	also  legal  to  supply  a
		    numeric argument to the -k option, in which case that signal number is used.

		    It is illegal to supply both the -a option and the -k option.

       -t	    Specifies the timeout period, in seconds.

       -v	    Verbose output, on stderr.

EXIT STATUS

       If the timeout occurs, then hatimerun exits with exit code 99 (which can be overridden to some other value using the -e option).

       If  the	timeout  does  not  occur but some other error is detected by the hatimerun utility (as opposed to the error being detected by the
       child program), then hatimerunhatimerun exits with exit code 98.

       Otherwise, hatimerun exits with the child's exit status.

       The hatimerun utility catches the signal SIGTERM. It responds to the signal by killing the child as if a timeout  had  occurred,  and  then
       exiting with exit code 98.
