I tried following on my 8.0-CURRENT box: ----8<----8<---- abbe [~] monte-cristo% exec sh $ echo "^$PKG-[0-9,._]+$" ^-[0-9,._]+$ $ uname -a FreeBSD monte-cristo.france 8.0-CURRENT FreeBSD 8.0-CURRENT #21: Mon Nov 10 21:19:13 IST 2008 root@monte-cristo.france:/usr/obj/usr/src/sys/ULE amd64 ---->8---->8---- And as you can see in above paste, 'sh' doesn't evaluate $" as variable as it has evaluated $PKG as variable. this works with 'sh' shipped with 8.0-CURRENT. Maybe some issue with your 'sh'.
