Depending on one definition of random ("I need a J. Random 5 meg file")
that works, However, another definition ("I need a file with 5 megs of
random data") this suggests a slightly different approach:

If new need some fairly random data but you need it now:
dd if=/dev/urandom of=somefile bs=1024k count=5

Or I need some REALLY good random data I'm going to use as one time pads
to encode missile launch codes with, but I don't care if it takes a
while to generate:

dd if=/dev/random of=somefile bs=1024k count=5
