basically it boils down to jq. Without it I never would have considered doing this task with bash. All JSON-Handling is done with jq. Bash is the code around it.
Even I may have considered differently after having it done, because the task got a little more complex than expected, I think I got the task done very quickly. It's working more than sufficiently well, the code is maintainable and the speed is acceptable. For smaller tasks I consider this still as an excellent choice.
We have EDP members will do some testing job in my system , but sometimes these process will generate some error to the system log or any file ( usually the members don't know the log is reached to this level ) , then make the system crashed , could suggest the way how can to prevent this problem ?...

iv_task
iv_task(3) ivykis programmer's manual iv_task(3)NAME
iv_task_register, iv_task_unregister, iv_task_registered - deal with ivykis tasks
SYNOPSIS
#include <iv.h>
struct iv_task {
void *cookie;
void (*handler)(void *);
};
void IV_TASK_INIT(struct iv_task *task);
void iv_task_register(struct iv_task *task);
void iv_task_unregister(struct iv_task *task);
int iv_task_registered(struct iv_task *task);
DESCRIPTION
The functions iv_task_register and iv_task_unregister register, respectively unregister, a task with the current thread's ivykis event
loop. iv_task_registered on a task returns true if that task is currently registered with ivykis.
A task is like a timer, but with an immediate timeout. When a task is registered, unless it is unregistered again first, the callback
function specified by ->handler is guaranteed to be called once, in the thread that the task was registered in, some time after control
returns to the ivykis main loop but before ivykis will sleep for more events, with ->cookie as its first and sole argument. When this hap-
pens, the task is transparently unregistered.
Tasks are mainly used for scheduling code for execution where it is not appropriate to directly run that code in the calling context (for
example, because the current context might be run as a callback function where the caller expects certain conditions to remain invariant
after the callback completes).
The application is allowed to change the ->cookie and ->handler members at any time.
A given struct iv_task can only be registered in one thread at a time, and a task can only be unregistered in the thread that it was regis-
tered from.
There is no limit on the number of tasks registered at once.
