| or \| without the grouping operator is a |; so I believe that I am correct.

try it with '(term1|term2|term3)'

possibly the quoting.  have you altered the cvs diff line itself, or use a
variable on that line?  for example, .* being glob expanded.  or possibly the
version of diff that you are getting as a result of differences in PATH?

But if I omit one of the elements (say 'threat'), it won't ignore any of the lines even though I would expect it to only return the 'threat' lines as different. Does anyone have any ideas or explanation of this behavior?
