Since it's not guaranteed to be present, why not just ignore $RANDOM
and use our own randomly generated integer instead? Something like:
groff_rand=$(dd if=/dev/urandom bs=8 count=1 2>/dev/null | sum | sed
's/^0*//;s/ .*//')
tmp="$d/eqn2graph$groff_rand"
should work and be portable. I think pretty much everywhere supports
/dev/urandom, right? If not we could use /dev/random with the minimal
chance of it blocking.
