Previous: The Match-beginning-of-line Operator (^), Up: Anchoring Operators [Contents][Index]
$)This operator can match the empty string either at the end of the string or before a newline character in the string. Thus, it is said to anchor the pattern to the end of a line.
It is always represented by ‘$’. For example, ‘foo$’ usually matches, e.g., ‘foo’ and, e.g., the first three characters of ‘foo\nbar’.
Its interaction with the syntax bits and pattern buffer fields is
exactly the dual of ‘^’’s; see the previous section. (That is,
“‘^’” becomes “‘$’”, “beginning” becomes “end”,
“next” becomes “previous”, “after” becomes “before”, and
“not_bol” becomes “not_eol”.)
