[Serusers] search string, circumflex

[Paul Jankowski]

> first-> search("^(Contact|m): .*@(192\.168\.|10\.|172\.16)")
> second-> search("(From|f):.*@foo.bar")

The string is a regular expression.  You can find out more about them
online (eg: http://sitescooper.org/tao_regexps.html ), or by typing

  man 7 regex

at the command line.


"(Contact|m)" means 'either the word "Contact" or the word "m"'.

A caret ^ at the beginning of the regular expression means "only match
if the following string is at the beginning of the line" -- so the first
expression would match

  Contact: che.sosa at 192.168.0.1

but would not match 

  I wish to Contact: che.sosa at 192.168.0.1

Have fun,

Paul
