Anchoring
You can instruct the system to match a regular expression pattern against the
beginning or the end of the string. You anchor these regular expressions to a
portion of the string using the special characters shown in
Table 2 ..
For example, the regular expression ^con matches any string that starts with con,
and $sole matches any string that ends with sole.
In addition to indicating the beginning of a string, the ^ symbol can be used to
indicate the logical function not when used in a bracketed range. For example, the
expression [^abcd] indicates a range that matches any single letter, as long as it is
not the letters a, b, c, or d.
