dtrace discuss - Nov 2005 - How to exclude multiple probe patterns ?

Hi,

Suppose we have thousands of functions in a module but only
want to exclude a few patterns.  In this case, it becomes
impractical trying to list all probe patterns except those
few you want to exclude.  One way to deal with this is to
use [! to exclude certain characters.  For example, if we
construct the clause below, we can exclude function
patterns with leading "xyz":

pid$target:mymod:[!x]*:entry,
pid$target:mymod:[x][!y]*:entry,
pid$target:mymod:[x][y][!z]*:entry
{
}
>From this example, we know it is possible to exclude single
pattern.  But, to me, it becomes a puzzle if we want to
exclude multiple patterns such as excluding additional
pattern with leading "abc".

What should we do?  or  Do we have simpler and more
clever alternatives?

THX.
