I suppose that there is a question about how do you want tit to run. Is it that you want them all in straight away but with no more that 10 running (presumably to manage the load/contention) or do you want to run in blocks of 10 where all 10 have to finish before you start the next block?
For instance if you have a job that just went to sleep for the number of seconds of it's job number, (1, 2, 3, 4, .... etc.) Would you want logic A or B?
Logic A Logic B
Logic A will work if you are sure you have no other background processes and 'simply':-
If you need logic B then you need to keep a track of them more carefully. You can use clever data holding processes to keep track of a specific process id, or if they will be unique enough, just count the running processes:-
The important bit
You need to consider
what you are searching for. Get it wrong and you might not submit anything or you might submit everything in one go.
how to make sure you don't find the grep you are searching with as a process itself else you are using up one of your planned ten background jobs
For consideration a, my example I just use a sleep, so you can see it in what I've coded. You need to be sure that you find the right things and that your 'single jobs' don't actually spawn sub-processes of the same name else you will count them twice. You could look for sub-processes of your running script if that is important to you.
For consideration b, I have set the search with an expression by wrapping a character in [ & ] This means that the grep will expand this to any string matching the expression (for which there is only one option, of course) but crucially it will ignore itself, because the expression doesn't match the square bracket itself.
Does anyone know what the equivalent command to pwait on Solaris is on DG/UX. I need my script to kick off a process and wait till it is complete before continuing with the script. (4 Replies)

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.

Morning,
I'm trying to execute a vbs from a .bat file. Can someone tell me what the difference is between these statements:
start c:\lib\runit.vbc
c:\lib\runit.vbs
When I run the batch with the 'start' parameter it doesn't seem to do anything. (1 Reply)
