Below is the linux script of generating 1Billion records of random numbers. Can someone successfully run it

for i in {1..1000000000} do echo $RANDOM >> file1.txt done

and share following details:

(1) The size of "file1.txt" (2) How much time it took? (3) OS version, Memory and CPU details of the machine on which it was executed. I have tried multiple system resources (on my VM) but script gets killed with "Out of memory" error in /car/log/messages file.
