Anchors

An anchor does not match a character; instead, it matches what comes before (or after) a character:

Description	Character	Example
Beginning of a string	^	'aba' -match '^a'
End of a string	$	'cbc' -match 'c$'
Word boundary	\b	'Band and Land' -match '\band\b'

Anchors are useful where a character, string, or word may appear elsewhere in a string...
