Error in finding the PID by grep and assigning to a variable
Hello All,
I am facing difficulty in getting the PID value & then assigning it to a variable,
kindly help me in resolving the issue.
Thanks a lot in advance.
The custom utility used inside the Test2.sh will process the file in a batch of 10 lines at once and for efficient memory management, once first batch is completed, it will start a new process of the custom_utility to process the next batch and this goes on till all batches are processed. command executing at shell: ./Test2.sh -f=./input.txt
The Test2.sh should not exit till all the batch process of this file are completed by the custom utility.
For this reason, i used the while loop in which i am grepping for the PID having the name custom_utility & the input file and assigning it to a variable. if variable is blank, come out of loop is the logic.
Though the Sub process is running, the SUB_PID is returning blank and it is coming out of loop
Test.sh only contains the while loop logic and it is working fine.
I am able to resolve my issue.
when i am using the ps -ef, it is not giving the complete command line arguments. That is the reason for the issue. ps auxw will return the complete command line arguments.
