Do you simply want to background each process and wait until they are all completed, WARNING untested off the top of my head, on my first cup of coffee code follows
Code:
for index in $(seq 1 10); do
pid_1=file_1&
pid_2=file_2&
pid_3=file_3&
while kill -0 $pid_1 -o kill -0 $pid_2 -o kill -0 $pid_3 ; do
sleep 1;
done
done

kill
KILL(2) System Calls Manual KILL(2)NAME
kill - send signal to a process
SYNOPSIS
kill(pid, sig);
DESCRIPTION
Kill sends the signal sig to the process specified by the process number in r0. See signal(2) for a list of signals.
The sending and receiving processes must have the same effective user ID, otherwise this call is restricted to the super-user.
If the process number is 0, the signal is sent to all other processes in the sender's process group; see tty(4).
If the process number is -1, and the user is the super-user, the signal is broadcast universally except to processes 0 and 1, the scheduler
and initialization processes, see init(8).
Processes may send signals to themselves.
SEE ALSO signal(2), kill(1)DIAGNOSTICS
Zero is returned if the process is killed; -1 is returned if the process does not have the same effective user ID and the user is not
super-user, or if the process does not exist.
ASSEMBLER
(kill = 37.)
