Simple question for the regEXperts out there...
I have a string that is always in the format: a.nn+x.y
a is always 5 chars
n can be 1 or 2 digits
x can be +/- (with sign), 1-4 digits
y is always positive

I am afraid, your suggestion is even breaking for
already working ones! i.e., it says HEXADECIMAL NUMBER
for an invalid string like f4dx and also says
HEXADECIMAL NUMBER for invalid empty strings.
The one I had posited,without the leading ^ and $
matched for all the cases correctly, except for

Would anchoring with \z tantamount to having a

i don't understand your answer. how will that match anything?
the first line matches the whole block ok, but then the match is dropped
by the '!' phrases
since they are in the text.
also, where is documented the ellipsis in a grep?
also, using two regexes on either side of the ellipsis?

sorry. still in dark.
what exactly does '/START_KEYWORD/.../END_KEYWORD/' mean?
I see a regex - /START_KEYWORD/
an ellipsis - ...
and a regex - /END_KEYWORD/
you are saying the whole thing means something, but I don't understand
what.
you say 'the elipsis returns false'
what does that mean?

Ah... i see.
in scalar context, it returns false until left is true. then returns true
until right is true.
just what we want. very handy.
thanks.

There's no need to match past the CN=, then prepend the CN= back to the
