Hi,there

I'm doing some R batch jobs in Unix. 
Something like
R <prog1> output1 --save &
R <prog2> output2 --save &

prog1 and prog2 are running at the same time and they are essentially same except it contains different parameter values. 
I was wondering if two processes will affect each other? Hopefully they are two independent jobs.

It's a beginner's question and thanks for your help.
