Hi,

Thanks for the reply.
So I understand if I run below it will run the 3 scripts in parallel.

test1.sh par1 &
test1.sh par2 &
test1.sh par3 &

Now I have 2 questions.

How UNIX will call test1.sh par2 & after test1.sh par1 &.
test1.sh par1 & we are running in backgroud , so after kicking this script shall it automatically kick test1.sh par2 & without considering the first one to fail or success?

SEA -->

Why we are calling wait call in your example?
wait $p1 && wait $p2 && wait $p3 - Is it when p1 completes it will start p2 ...

Request you to please explain this.

Thnaks in advance.

NAME
cgexec - run the task in given control groups SYNOPSIS
cgexec [-h] [-g <controllers>:<path>] [--sticky] command [arguments] DESCRIPTION
The cgexec program executes the task command with arguments arguments in the given control groups. -g <controllers>:<path> defines the control groups in which the task will be run. controllers is a list of controllers and path is the relative path to control groups in the given controllers list. This flag can be used multiple times to define multiple pairs of lists of controllers and relative paths. Instead of the list of all mounted controllers, the wildcard b"*b" can be used. If this option is not used, cgexec will automatically place the task in the right cgroup based on /etc/cgrules.conf. -h, --help Display this help and exit. --sticky If running the task command with this option, the daemon of service cgred (cgrulesengd process) does not change both the task of the command and the child tasks. Without this option, the daemon does not change the task of the command but it changes the child tasks to the right cgroup based on /etc/cgrules.conf automatically. EXAMPLES
cgexec -g *:test1 ls runs command ls in control group test1 in all mounted controllers. cgexec -g cpu,memory:test1 ls -l runs command ls -l in control group test1 in controllers cpu and memory. cgexec -g cpu,memory:test1 -g swap:test2 ls -l runs command ls -l in control group test1 in controllers cpu and memory and control group test2 in controller swap.
