If it is running, then there is a pid on stdout, and a new run will be a duplicate. By tying stdout to stderr, you can get the letters that say it is being run (not just viewed or whatever) (fuser puts pids and separating white space on stdout and all else on stderr).
You can write the job's pid in a control file named for the job, and search for a running copy that way, but fuser is cleaner and simpler. Binding a socket can be exclusive, too.
Hi there,

cgexec
CGEXEC(1) libcgroup Manual CGEXEC(1)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.
