Question

I was trying to find out the ways to create a child process through Shell Script but I couldn’t.
I wonder why Shell script command has the command that kills the process but not creates it.

Answer 1

The shell has a myriad different ways of creating processes; most of what a shell script does is execute processes.

process
process &
process1 | process2
if process1
then process2
else process3
fi
(process)
x=$(process)

And so on, ad nauseam.
