here's the problem:
parse a file with grep and find all the lines that do not
start with z9 or t9 without using any options for grep (and no egrep)
grep '^[^t][^9]' datafile | grep '^[^z][^9]' > output.temp
but that will kill some of the lines i need (z1's and t3's)
any ideas? remember, no grep options and no egrep.
more than one grep statement will most likely be used.
