So, I just wanted to know So, I just wanted to know how 2 or more scripts can be run in parallel. I searched a few places and saw mentions of using the '&' in between the various scripts I have but I would not be sure. So, can anyone provide me ideas how it can be possible or various ways I can initiate the process?

Simplest way :
#!/bin/sh
/usr/bin/my-process-1 --args1 &
/usr/bin/my-process-2 --args2 &
/usr/bin/my-process-3 --args3 &
wait
echo all processes complete

So only using the & between the scripts is the way to do it? Thanks – jake elias Jan 24 '18 at 16:37

It's the easiest way you got to do it, but you can check in the link for more ways to do it, if the & is a problem ! – Alexandre Beaudet Jan 25 '18 at 15:48

Using & that put the application in the background.
from the man bash.
If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.
For example.
Running shell script with shell script you can do like this,
#!/bin/bash
sh ./script1 &
sh ./script2 &
