Hello everyone!
I am GSOC student at FreeBSD Project.
So my GSOC Project is "Parallelization in the ports collection".
You may checkout wiki page of this project:
http://wiki.freebsd.org/SummerOfCode2012/Parallelization_in_the_ports_collection
Is it suitable to write sh script for 9.0, that does not work in 8.3?
To sum up, the scenario is as following:
I need to spawn some processes in background to build port's dependencies.
Store their pids.
Wait for a while or do some stuff.
explore exit codes of spawned processes by their pids.
The problem is:
### sh in 8.3
$ false & pid=$!
$
[1] Done (1) false
$ wait ${pid}
wait: No such job: 4852
-----------------------
### sh in releng9
$ false & pid=$!
$
[1] Done(1) false
$ wait ${pid}
$ echo $?
1
$
I am currently working in releng9 environment, so the result suits my needs.
But, is it suitable to write sh script for 9.0, that does not work in 8.3?
