OT: many script or many fork?

[Roberto A. Foglietta]

Hi to all folks,

 sorry for the OT but I am wondering if it would be better have three
indipendent script which runs concurrently or it is better having only
a script like this:

 while true; do
        [ ... code 1 ... ]
 done &

 while true; do
        [ ... code 2 ... ]
 done &

 while true; do
        [ ... code 3 ... ]
 done

 Thanks in advance,
