background process return code
Hi
I have the following piece of code that is calling another child process archive.ksh in the background
while read file;
do
file_name=`ls $file`;
ksh archive.ksh $file_name &;
done < $indirect_file
The problem is, indirect_file may contain anwhere from 2 to 20 different filenames and archive.ksh takes only one file name at a time (that is a limitation). So based on the number of files in indirect_file, i shall run those many background processes for archive.ksh.
I need to check for the completion of all archive.ksh jobs that i fired in the background and only if all the bg jobs are successful, i need to make this process pass otherwise I abort it.
I found that there is a wait command that will wait for bg jobs to finish..Can I use it? if yes, how do i overcome following prob :
1. How do I specify the job id or pid to wait command when I dont know it beforehand?
2. I have heard that there is a restriction on the number of jobs you can fire? What is the number?
Any ideas??
Thanks
