wow, thats cool. I didnt think to mention awk or sed.
That will work fine. Thanks.

Does it check to see if the bit is already set?

Oh, yeah, both of those are awk scripts. You could do it with sed as well, of course, but I don't know the bitwise operators in sed.

No, it doesn't check - but it's a bitwise or, so nothing should change if the bit is set already (or isn't set already, depending.)

If you add something like:
Code:

---

if (and($3,mask)==mask){print mask " already set at " $2;}

---

It'll check bitmasks as well.
