bash: start multiple chained commands in background

Question

I\'m trying to run some commands in paralel, in background, using bash. Here\'s what I\'m trying to do:

forloop {
  //this part is actually written in perl
          


        

Answer 1

Try to put commands in curly braces with &s, like this:

{command1 & ; command2 & ; command3 & ; }

This does not create a sub-shell, but executes the group of commands in the background.
