Have you considered using mktemp rather than having statically named
temporary directories and files?
export TMPDIR=$(mktemp -d)
temp0=$(mktemp)
temp1=$(mktemp)
... etc ...
See the mktemp(1) man page for an explanation of why I set the TMPDIR
variable that way.
It might not be worth it on a single-user workstation or when you're
100% sure the script will never be run simultaneously with itself. But
I've found that using mktemp is a good habit, over the long haul.
