Start a process with a name

Question

Basically I want to dynamically start some processes which may create their own children processes, also I want to kill a certain group of processes I just created whenever I want. One way I could think of is to start processes with a name(to distinguish as a group), then use pkill to kill them by the name. The question is how to start a process with a name so that I can use pkill to kill them by the name? I am open to other solutions as well.

Solution

How can I start a process with a different name?

bash -c "exec -a <MyProcessName> <Command>"

Then you can kill the process with:

pkill -f MyProcessName

I'm trying this with nodejs and it doesn't work, process name is always node. I'm using this exec -a myprocess node server.js. I can't get anything by using pidof myprocess and pgrep myprocess. However when I try to find the name of the process by the process ID I get node

The same problem. -a does not set the name. no error but nor name.
