I have this bash script;

for (( i = 1 ; i <= 160 ; i++ )); do
qsub myccomputations"${i}".pbs
done

Basically, I would prefer if there was a 1 second delay between each iteration. The reason is that at each iterations, it sends the program file mycomputation"${i}$.pbs to a core node for solving.

Solving in this instance involves the use of pseudo random numbers. I suspect the RNG I use (R's) uses CPU time as seed because as things are now I get repeating pseudo random numbers (at the rate of approx 1 out of 100).

So how to you ask bash to

for (( i = 1 ; i <= 160 ; i++ )); do
wait 1 sec    
qsub myccomputations"${i}".pbs
done
