Shells (bash, ksh, etc) do not propagate signals to non-builtin commands. To illustrate this a bit better, I replaced the sleep in your script with a script tasker
Nothing fancy, it counts down from 9 with one second delays. So your script is now (with some echos):
And when run:
What you need to do is have the watchdog kill the subprocess directly:
Which runs as:
Now if the task finishes first, the script will still sleep for the full interval:
Hope this helps.

I have not written any code in about 15 years. The company I work for has Unix servers and they utilize KSH. The scriptors say that what I want can only be scripted in PERL which on my server they say they cannot get to work. They also tell me that what I want done cannot be... (0 Replies)

hatimerun(1M) System Administration Commands hatimerun(1M)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.
