I don't see where the argument limit will hit.. `for' is a shell
internal, and touch only has one argument. The output from the
backticks is internal due to the nature of `for' (as is my
understanding)
Actually, I've done:
for i in `seq 1 2147483648`; do echo $i; done
and before I hit any (sanity imposed) limit, my system slowed to a crawl
as the swap started thrashing, bash was using over 100M of virtual
memory, and seq was hogging all the CPU. The darn thing died with a
segfault the first time, and the second time complained that malloc
couldn't allocate something in the order of 4G of memory :)
