[geeks] Regular Expressions

[Mailing Lists Address]

I topyed with it some more, and ended up using:

egrep '[2][2-3][0-9]\.[0-9].*\.[0-9].*\.[0-9].*'

to fix my debacle. On further examiniation of the egrep man page, I saw

"The /usr/bin/egrep utility accepts full regular  expressions
 as described on the regexp(5) manual page, except for \( and
 \), \( and \), \{ and \}, \< and \>, and \n,  and  with  the
 addition of:"

I read it kinda fast the first time, and missed the "except". The
regexp above fixed my issue. I also needed to update the third range
operator.
