Why not just chain them:
ifconfig eth0 | grep -E [RT]X > `date +%y%m%d`.stats
which will alleviate using a temp file (or too many variables).

BTW, the modification I made to grep above will capture both RX & TX lines.
What you have above will only catch RX lines.

Basic accounting is kept for all chains and rules. To see that data, just do:
iptables -L -v
Verbose modes will report that (first two columns are packets and bytes for
the rules). Set a few rules (even just ACCEPT rules, if you're not doing any
filtering), and grep/awk the data as necessary. :-)
