Thanks Nikola and Bob.
Would "anchoring with \z" tantamount to having a
trailing "$"? In other words, are the following
expressions one and the same?
/^[0-9a-fA-F]+\z/
/^[0-9a-fA-F]+$/

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 "$"
matched for all the cases correctly, except
see below
/^[^0-9a-fA-F]+$/ #if this evals to true string is NOT
## start of string ^ and end of string $

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? w

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. Ignore that. It's 5:30 and home time. What can I say.
Use this instead.

There's no need to match past the CN=, then prepend the CN= back to the
string. Use the following
$dnvalue = "CN=foo,OU=bar,O=pah";
$dnvalue =~ /(CN=[A-Za-z0-9]*)/;
$username = $1;
print $username
This looks for CN= followed by any number of letters (upper or lowercase)
and numbers. If you don'
