Issue with tracking successful completion of Child process running in background
Hello All,
I am using Linux. I have two scripts:
inner_script.ksh
main_wrapper_calling_inner.ksh
Below is the code snippet of the main_wrapper_calling_inner.ksh:
Config File abc.txt has newline separated values like:
Below is the code snippet for inner_script.ksh:
Scenario:
I am trying to execute the inner_script in parallel for each of the value in config file abc.txt and to track the completion of each child process. I want the entire execution time to be the maximum execution time of any child process.
Problem:
Parent is unable to track the successful completion of some of the child process. Atleast one child process becomes Zombie or defunct. .
I am using zombie_lst=$(ps axo pid=,stat= | awk '$2~/^Z/ { print $1 }'|grep "$p") to identify if a child has become zombie and then trying to WAIT on that. Does WAIT works with a Zombie process? .
At the end...I am doing a KILL -TERM ${p} if the child has become a Zombie. Is this KILL -TERM ${p} actually killing the entire process?
Kindly suggest.
